+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1991 Free Software Foundation, Inc.
+ 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the library GPL. It is
+ numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+ This license, the Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it. You can use it for
+your libraries, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if
+you distribute copies of the library, or if you modify it.
+
+ For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you. You must make sure that they, too, receive or can get the source
+code. If you link a program with the library, you must provide
+complete object files to the recipients so that they can relink them
+with the library, after making changes to the library and recompiling
+it. And you must show them these terms so they know their rights.
+
+ Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+ Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library. If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, so that any problems introduced by others will not reflect on
+the original authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software. To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+ Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License, which was designed for utility programs. This
+license, the GNU Library General Public License, applies to certain
+designated libraries. This license is quite different from the ordinary
+one; be sure to read it in full, and don't assume that anything in it is
+the same as in the ordinary license.
+
+ The reason we have a separate public license for some libraries is that
+they blur the distinction we usually make between modifying or adding to a
+program and simply using it. Linking a program with a library, without
+changing the library, is in some sense simply using the library, and is
+analogous to running a utility program or application program. However, in
+a textual and legal sense, the linked executable is a combined work, a
+derivative of the original library, and the ordinary General Public License
+treats it as such.
+
+ Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries. We
+concluded that weaker conditions might promote sharing better.
+
+ However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves. This Library General Public License is intended to
+permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them. (We have not seen how to achieve
+this as regards changes in header files, but we have achieved it as regards
+changes in the actual functions of the Library.) The hope is that this
+will lead to faster development of free libraries.
+
+ The precise terms and conditions for copying, distribution and
+modification follow. Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library". The
+former contains code derived from the library, while the latter only
+works together with the library.
+
+ Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+ GNU LIBRARY GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any software library which
+contains a notice placed by the copyright holder or other authorized
+party saying it may be distributed under the terms of this Library
+General Public License (also called "this License"). Each licensee is
+addressed as "you".
+
+ A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+ The "Library", below, refers to any such software library or work
+which has been distributed under these terms. A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language. (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+ "Source code" for a work means the preferred form of the work for
+making modifications to it. For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+ Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it). Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+ 1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+ You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+ 2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) The modified work must itself be a software library.
+
+ b) You must cause the files modified to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ c) You must cause the whole of the work to be licensed at no
+ charge to all third parties under the terms of this License.
+
+ d) If a facility in the modified Library refers to a function or a
+ table of data to be supplied by an application program that uses
+ the facility, other than as an argument passed when the facility
+ is invoked, then you must make a good faith effort to ensure that,
+ in the event an application does not supply such function or
+ table, the facility still operates, and performs whatever part of
+ its purpose remains meaningful.
+
+ (For example, a function in a library to compute square roots has
+ a purpose that is entirely well-defined independent of the
+ application. Therefore, Subsection 2d requires that any
+ application-supplied function or table used by this function must
+ be optional: if the application does not supply it, the square
+ root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library. To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License. (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.) Do not make any other change in
+these notices.
+
+ Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+ This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+ 4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+ If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library". Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+ However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library". The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+ When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library. The
+threshold for this to be true is not precisely defined by law.
+
+ If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work. (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+ Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+ 6. As an exception to the Sections above, you may also compile or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+ You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License. You must supply a copy of this License. If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License. Also, you must do one
+of these things:
+
+ a) Accompany the work with the complete corresponding
+ machine-readable source code for the Library including whatever
+ changes were used in the work (which must be distributed under
+ Sections 1 and 2 above); and, if the work is an executable linked
+ with the Library, with the complete machine-readable "work that
+ uses the Library", as object code and/or source code, so that the
+ user can modify the Library and then relink to produce a modified
+ executable containing the modified Library. (It is understood
+ that the user who changes the contents of definitions files in the
+ Library will not necessarily be able to recompile the application
+ to use the modified definitions.)
+
+ b) Accompany the work with a written offer, valid for at
+ least three years, to give the same user the materials
+ specified in Subsection 6a, above, for a charge no more
+ than the cost of performing this distribution.
+
+ c) If distribution of the work is made by offering access to copy
+ from a designated place, offer equivalent access to copy the above
+ specified materials from the same place.
+
+ d) Verify that the user has already received a copy of these
+ materials or that you have already sent this user a copy.
+
+ For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it. However, as a special exception,
+the source code distributed need not include anything that is normally
+distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+ It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system. Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+ 7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+ a) Accompany the combined library with a copy of the same work
+ based on the Library, uncombined with any other library
+ facilities. This must be distributed under the terms of the
+ Sections above.
+
+ b) Give prominent notice with the combined library of the fact
+ that part of it is a work based on the Library, and explaining
+ where to find the accompanying uncombined form of the same work.
+
+ 8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License. Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License. However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+ 9. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Library or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+ 10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all. For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded. In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+ 13. The Free Software Foundation may publish revised and/or new
+versions of the Library General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation. If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission. For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this. Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+ NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ Appendix: How to Apply These Terms to Your New Libraries
+
+ If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change. You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+ To apply these terms, attach the following notices to the library. It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the library's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This library is free software; you can redistribute it and/or
+ modify it under the terms of the GNU Library General Public
+ License as published by the Free Software Foundation; either
+ version 2 of the License, or (at your option) any later version.
+
+ This library is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
+ Library General Public License for more details.
+

+ License along with this library; if not, write to the Free
+ Software Foundation, Inc., 59 Temple Place - Suite 330, Boston,
+ MA 02111-1307, USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary. Here is a sample; alter the names:

+Installation Instructions
+*************************
+
+Copyright (C) 1994-1996, 1999-2002, 2004-2013 Free Software Foundation,
+Inc.
+
+ Copying and distribution of this file, with or without modification,
+are permitted in any medium without royalty provided the copyright
+notice and this notice are preserved. This file is offered as-is,
+without warranty of any kind.
+
+Basic Installation
+==================
+
+ Briefly, the shell command `./configure && make && make install'
+should configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package. Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below. The lack of an optional feature in a given package is not
+necessarily a bug. More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package, generally using the just-built uninstalled binaries.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation. When installing into a prefix owned by root, it is
+ recommended that the package be configured and built as a regular
+ user, and only the `make install' phase executed with root
+ privileges.
+
+ 5. Optionally, type `make installcheck' to repeat any self-tests, but
+ this time using the binaries in their final installed location.
+ This target does not install anything. Running this target as a
+ regular user, particularly if the prior `make install' required
+ root privileges, verifies that the installation completed
+ correctly.
+
+ 6. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 7. Often, you can also type `make uninstall' to remove the installed
+ files again. In practice, not all packages have tested that
+ uninstallation works correctly, even though it is required by the
+ GNU Coding Standards.
+
+ 8. Some packages, particularly those that use Automake, provide `make
+ distcheck', which can by used by developers to test that all other
+ targets like `make install' and `make uninstall' work correctly.
+ This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'. This
+is known as a "VPATH" build.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them. In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+ The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+ The first method involves providing an override variable for each
+affected directory. For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'. Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated. The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+ The second method involves providing the `DESTDIR' variable. For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names. The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters. On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+ Some packages offer the ability to configure how verbose the
+execution of `make' will be. For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved. Use GNU `make'
+instead.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+ On Solaris, don't put `/usr/ucb' early in your `PATH'. This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+ On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'. It is recommended to use the following options:
+
+ ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS
+ KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf limitation. Until the limitation is lifted, you can use
+this workaround:
+
+ CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+INTRODUCTION
+============
+
+The NTFS-3G driver is an open source, freely available read/write NTFS driver
+for Linux, FreeBSD, Mac OS X, NetBSD, OpenSolaris, QNX and Haiku. It provides
+safe and fast handling of the Windows XP, Windows Server 2003, Windows 2000,
+Windows Vista, Windows Server 2008 and Windows 7 file systems.
+
+The purpose of the project is to develop, quality assurance and support a
+trustable, featureful and high performance solution for hardware platforms
+and operating systems whose users need to reliably interoperate with NTFS.
+Besides this practical goal, the project also aims to explore the limits
+of the hybrid, kernel/user space filesystem driver approach, performance,
+reliability and feature richness per invested effort wise.
+
+Besides the common file system features, NTFS-3G has support for file
+ownership and permissions, POSIX ACLs, junction points, extended attributes
+and creating compressed files. Parameter files in the directory .NTFS-3G may
+be required to enable them, please get the instructions from
+
+ http://www.tuxera.com/community/ntfs-3g-advanced/
+
+News, support answers, problem submission instructions, support and discussion
+forums, performance numbers and other information are available on the project
+web site at
+
+ http://www.tuxera.com/community/
+
+LICENSES
+========
+
+All the NTFS related components : the file system drivers, the ntfsprogs
+utilities and the shared library libntfs-3g are distributed under the terms
+of the GNU General Public License as published by the Free Software
+Foundation; either version 2 of the License, or (at your option) any later
+version. See the included file COPYING.
+
+The fuse-lite library is distributed under the terms of the GNU LGPLv2.
+See the included file COPYING.LIB.
+
+QUICK INSTALLATION
+==================
+
+Linux: Make sure you have the basic development tools and the kernel includes
+the FUSE kernel module. Then unpack the source tarball and type:
+
+ ./configure
+ make
+ make install # or 'sudo make install' if you aren't root.
+
+Please note that NTFS-3G doesn't require the FUSE user space package any
+more.
+
+The list of options for building specific configurations is displayed by
+typing :
+
+ ./configure --help
+
+Below are a few specific options to ./configure :
+ --disable-ntfsprogs : do not build the ntfsprogs tools,
+ --enable-posix-acls : enable support for Posix ACLs
+ --enable-xattr-mappings : enable system extended attributes mappings
+ --with-fuse=external : use external fuse (overriding Linux default)
+
+There are also a few make targets for building parts :
+ make libntfs : only build the libntfs-3g library
+ make libs : only build libntfs-3g (and libfuse-lite, if relevant)
+ make drivers : only build drivers and libraries, without ntfsprogs
+ make ntfsprogs : only build ntfsprogs and libntfs-3g, without drivers
+
+Non-Linux: Please see
+
+ http://www.tuxera.com/community/ntfs-3g-download/
+
+for known OS specific installation and source packages, but generally
+the same procedures apply.
+
+USAGE
+=====
+
+If there was no error during installation then the NTFS volume can be
+read-write mounted for everybody the following way as the root user
+(unmount the volume if it was already mounted, and replace /dev/sda1
+and /mnt/windows, if needed):
+
+ mount -t ntfs-3g /dev/sda1 /mnt/windows
+or
+ ntfs-3g /dev/sda1 /mnt/windows
+
+Please see the ntfs-3g manual page for more options and examples.
+
+You can also make NTFS to be mounted during boot by putting the below
+line at the END(!) of the /etc/fstab file:
+
+ /dev/sda1 /mnt/windows ntfs-3g defaults 0 0
+
+
+TESTING WITHOUT INSTALLING
+=========================
+
+Newer versions of ntfs-3g can be tested without installing anything and
+without disturbing an existing installation. Just configure and make as
+shown previously. This will create the scripts ntfs-3g and lowntfs-3g
+in the src directory, which you may activate for testing :
+
+ ./configure
+ make
+
+then, as root :
+ src/ntfs-3g [-o mount-options] /dev/sda1 /mnt/windows
+
+And, to end the test, unmount the usual way :
+ umount /dev/sda1
+
+
+NTFS UTILITIES
+==============
+
+The ntfsprogs includes utilities for doing all required tasks to NTFS
+partitions. In general, just run a utility without any command line
+options to display the version number and usage syntax.
+
+The following utilities are so far implemented:
+
+ntfsfix - Attempt to fix an NTFS partition and force Windows to check NTFS.
+
+mkntfs - Format a partition with the NTFS filesystem. See man 8 mkntfs for
+command line options.
+
+ntfslabel - Display/change the label of an NTFS partition. See man 8 ntfslabel
+for details.
+
+ntfsundelete - Recover deleted files from an NTFS volume. See man 8
+ntfsundelete for more details.
+
+ntfsresize - Resize NTFS volumes. See man 8 ntfsresize for details.
+
+ntfsclone - Efficiently create/restore an image of an NTFS partition. See
+man 8 ntfsclone for details.
+
+ntfscluster - Locate the owner of any given sector or cluster on an NTFS
+partition. See man 8 ntfscluster for details.
+
+ntfsinfo - Show some information about an NTFS partition or one of the files
+or directories within it. See man 8 ntfsinfo for details.

+**********
+* mkntfs *
+**********
+
+- Correct support for creating volumes with larger sector sizes (mft record
+ size, cluster size, and index block size must be >= sector size), so for 1k,
+ 2k, and 4k sectors, we need to set the default mft record, cluster, and index
+ block size to be at least the sector size.
+- Correct the odd last partition sector not being accessible under 2.4 kernels
+ by setting the device block size to the sector size (default is 1k on 2.4
+ kernels and they can't cope with partial sectors).
+- Got a report that creating a floppy with mkntfs failed. Difference between
+ this floppy and the floppy created by the special tool found on the net was
+ said to be that the bitmap is 256kib on the special floppy while mkntfs will
+ make it much smaller. Need to verify this and experiment with the bitmap
+ size to make it work. Note, reporter was using win2k.
+
+
+*************
+* ntfsclone *
+*************
+
+- get rid of the unneeded lseek()'s during reads/writes (probably it
+ doesn't improve performance much, or any at all)
+- catch if source and dest are the same
+- disable consistency check for --metadata (e.g. if the check is crashing)
+- option: --inode
+- option: --data
+- metadata cloning: skip more non-needed inodes
+- manual: document LFS issues (smbfs' lfs option, nfs)
+- manual: mention optimized seeks
+- manual: optimal backup if disks have bad sectors
+- manual: ntfsclone guarantees the restored image works only
+ if one restores to the exactly same partition. For example,
+ one can not copy system partition to a different partition:
+ minimum "hidden sectors" field and BOOT.INI need modifications.
+ We could do these adjustments optionally.
+- check if kernel block size = GCD(page size, device size) makes
+ effect on performance (Al Viro says no)
+- check whether the O_WRONLY -> O_RDWR change made effect on performance
+
+
+***********
+* ntfscmp *
+***********
+
+- compare mft record headers
+- exit status is 0 if inputs are the same, 1 if different, other if trouble
+- optionally ignore less interesting fields (e.g. attribute instance)
+- new option: --metadata mode
+- unnamed resident attributes with same type are ignored
+- code cleanup, remove many cross-util duplicates
+- handle deleted records
+- performance: special handling for sparse files
+
+
+**********
+* ntfscp *
+**********
+
+- add ability to copy multiple files at once.
+
+
+***********
+* ntfsfix *
+***********
+
+- Cleanup to use ntfs_attr_* API for editing $MFTMirr, $Volume, and $LogFile.
+ This has the immediate benefit of enabling attribute list support and making
+ the code simpler.
+- On ntfs 3.0+ volumes need to disable the usn journal if it is active. This
+ means deleting file $UsnJrnl from /$Extend directory.
+- On ntfs 3.0+ volumes need to mark the quota out of date? - Probably, but
+ it shouldn't cause any corruption not doing so for the moment so this is
+ not a showstopper bug for the first release. (AIA)
+
+
+*************
+* ntfslabel *
+*************
+
+- Support ioctls for kernel driver and ntfsmount for reading/changing the label.
+
+
+*************
+* ntfsmount *
+*************
+
+
+
+**************
+* ntfsresize *
+**************
+
+High priority
+ - move ntfs consistency check to libntfs (for ntfsck, ntfsclone, etc)
+ - use different exit codes (e.g. corrupt volume detected, unsupported case,
+ bad sectors, etc)
+
+Medium priority
+ - cope with the rare, unsupported cases, see man ntfsresize 'KNOWN ISSUES'
+ - save $Bitmap if it was modified and an error occures (e.g. bad sector).
+ - handle signals (^C, etc)
+
+Low priority
+ - fully support disks with bad sectors (attrlist attr, unknown bad sectors)
+ - move volume start
+
+
+****************
+* ntfsundelete *
+****************
+
+- undelete by name rather than inode number
+- support for compressed files
+- support for internationalisation
+- recover by type?
+- mass undelete (using wildcards)
+- display parent directory
+- name "<none>" to MFTn

+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+\`configure' configures ntfs-3g 2015.3.14 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]

+ *
+ * More than one such match may occur, in which case the action for
+ * each match is executed.
+ *
+ * There are three possible actions in case of a match:
+ *
+ * i) An integer (int or unsigned) variable determined by 'offset' is
+ * set to 'value'
+ *
+ * ii) The processing function is called, with 'value' as the key
+ *
+ * iii) An integer (any) or string (char *) variable determined by
+ * 'offset' is set to the value of an option parameter
+ *
+ * 'offset' should normally be either set to
+ *
+ * - 'offsetof(struct foo, member)' actions i) and iii)
+ *
+ * - -1 action ii)
+ *
+ * The 'offsetof()' macro is defined in the <stddef.h> header.
+ *
+ * The template determines which options match, and also have an
+ * effect on the action. Normally the action is either i) or ii), but
+ * if a format is present in the template, then action iii) is
+ * performed.
+ *
+ * The types of templates are:
+ *
+ * 1) "-x", "-foo", "--foo", "--foo-bar", etc. These match only
+ * themselves. Invalid values are "--" and anything beginning
+ * with "-o"
+ *
+ * 2) "foo", "foo-bar", etc. These match "-ofoo", "-ofoo-bar" or
+ * the relevant option in a comma separated option list
+ *
+ * 3) "bar=", "--foo=", etc. These are variations of 1) and 2)
+ * which have a parameter
+ *
+ * 4) "bar=%s", "--foo=%lu", etc. Same matching as above but perform
+ * action iii).
+ *
+ * 5) "-x ", etc. Matches either "-xparam" or "-x param" as
+ * two separate arguments
+ *
+ * 6) "-x %s", etc. Combination of 4) and 5)
+ *

+ * 1st: a1 61 65 b7 65 7b d4 11 9e 3d 00 e0 81 10 42 59

+ * Attribute compression.
+ *
+ * Only the data attribute is ever compressed in the current ntfs driver in
+ * Windows. Further, compression is only applied when the data attribute is
+ * non-resident. Finally, to use compression, the maximum allowed cluster size
+ * on a volume is 4kib.
+ *
+ * The compression method is based on independently compressing blocks of X
+ * clusters, where X is determined from the compression_unit value found in the
+ * non-resident attribute record header (more precisely: X = 2^compression_unit
+ * clusters). On Windows NT/2k, X always is 16 clusters (compression_unit = 4).
+ *
+ * There are three different cases of how a compression block of X clusters
+ * can be stored:
+ *
+ * 1) The data in the block is all zero (a sparse block):
+ * This is stored as a sparse block in the runlist, i.e. the runlist
+ * entry has length = X and lcn = -1. The mapping pairs array actually
+ * uses a delta_lcn value length of 0, i.e. delta_lcn is not present at
+ * all, which is then interpreted by the driver as lcn = -1.
+ * NOTE: Even uncompressed files can be sparse on NTFS 3.0 volumes, then
+ * the same principles apply as above, except that the length is not
+ * restricted to being any particular value.
+ *
+ * 2) The data in the block is not compressed:
+ * This happens when compression doesn't reduce the size of the block
+ * in clusters. I.e. if compression has a small effect so that the
+ * compressed data still occupies X clusters, then the uncompressed data
+ * is stored in the block.
+ * This case is recognised by the fact that the runlist entry has
+ * length = X and lcn >= 0. The mapping pairs array stores this as
+ * normal with a run length of X and some specific delta_lcn, i.e.
+ * delta_lcn has to be present.
+ *
+ * 3) The data in the block is compressed:
+ * The common case. This case is recognised by the fact that the run
+ * list entry has length L < X and lcn >= 0. The mapping pairs array
+ * stores this as normal with a run length of X and some specific
+ * delta_lcn, i.e. delta_lcn has to be present. This runlist entry is
+ * immediately followed by a sparse entry with length = X - L and
+ * lcn = -1. The latter entry is to make up the vcn counting to the
+ * full compression block size X.
+ *
+ * In fact, life is more complicated because adjacent entries of the same type
+ * can be coalesced. This means that one has to keep track of the number of
+ * clusters handled and work on a basis of X clusters at a time being one
+ * block. An example: if length L > X this means that this particular runlist
+ * entry contains a block of length X and part of one or more blocks of length
+ * L - X. Another example: if length L < X, this does not necessarily mean that
+ * the block is compressed as it might be that the lcn changes inside the block
+ * and hence the following runlist entry describes the continuation of the
+ * potentially compressed block. The block would be compressed if the
+ * following runlist entry describes at least X - L sparse clusters, thus
+ * making up the compression block length as described in point 3 above. (Of
+ * course, there can be several runlist entries with small lengths so that the
+ * sparse entry does not follow the first data containing entry with
+ * length < X.)
+ *
+ * NOTE: At the end of the compressed attribute value, there most likely is not
+ * just the right amount of data to make up a compression block, thus this data
+ * is not even attempted to be compressed. It is just stored as is, unless
+ * the number of clusters it occupies is reduced when compressed in which case
+ * it is stored as a compressed compression block, complete with sparse
+ * clusters at the end.

+ * Build an ACL composed of several ACE's
+ * returns size of ACL or zero if failed
+ *
+ * Three schemes are defined :
+ *
+ * 1) if root is neither owner nor group up to 7 ACE's are set up :
+ * - denials to owner (preventing grants to world or group to apply)
+ * + mask denials to designated user (unless mask allows all)
+ * + denials to designated user
+ * - grants to owner (always present - first grant)
+ * + grants to designated user
+ * + mask denial to group (unless mask allows all)
+ * - denials to group (preventing grants to world to apply)
+ * - grants to group (unless group has no more than world rights)
+ * + mask denials to designated group (unless mask allows all)
+ * + grants to designated group
+ * + denials to designated group
+ * - grants to world (unless none)
+ * - full privileges to administrator, always present
+ * - full privileges to system, always present
+ *
+ * The same scheme is applied for Posix ACLs, with the mask represented
+ * as denials prepended to grants for designated users and groups
+ *
+ * This is inspired by an Internet Draft from Marius Aamodt Eriksen
+ * for mapping NFSv4 ACLs to Posix ACLs (draft-ietf-nfsv4-acl-mapping-00.txt)
+ * More recent versions of the draft (draft-ietf-nfsv4-acl-mapping-05.txt)
+ * are not followed, as they ignore the Posix mask and lead to
+ * loss of compatibility with Linux implementations on other fs.
+ *
+ * Note that denials to group are located after grants to owner.
+ * This only occurs in the unfrequent situation where world
+ * has more rights than group and cannot be avoided if owner and other
+ * have some common right which is denied to group (eg for mode 745
+ * executing has to be denied to group, but not to owner or world).
+ * This rare situation is processed by Windows correctly, but
+ * Windows utilities may want to change the order, with a
+ * consequence of applying the group denials to the Windows owner.
+ * The interpretation on Linux is not affected by the order change.
+ *
+ * 2) if root is either owner or group, two problems arise :
+ * - granting full rights to administrator (as needed to transpose
+ * to Windows rights bypassing granting to root) would imply
+ * Linux permissions to always be seen as rwx, no matter the chmod
+ * - there is no different SID to separate an administrator owner
+ * from an administrator group. Hence Linux permissions for owner
+ * would always be similar to permissions to group.
+ *
+ * as a work-around, up to 5 ACE's are set up if owner or group :
+ * - grants to owner, always present at first position
+ * - grants to group, always present
+ * - grants to world, unless none
+ * - full privileges to administrator, always present
+ * - full privileges to system, always present
+ *
+ * On Windows, these ACE's are processed normally, though they
+ * are redundant (owner, group and administrator are the same,
+ * as a consequence any denials would damage administrator rights)
+ * but on Linux, privileges to administrator are ignored (they
+ * are not needed as root has always full privileges), and
+ * neither grants to group are applied to owner, nor grants to
+ * world are applied to owner or group.
+ *
+ * 3) finally a similar situation arises when group is owner (they
+ * have the same SID), but is not root.
+ * In this situation up to 6 ACE's are set up :
+ *
+ * - denials to owner (preventing grants to world to apply)
+ * - grants to owner (always present)
+ * - grants to group (unless groups has same rights as world)
+ * - grants to world (unless none)
+ * - full privileges to administrator, always present
+ * - full privileges to system, always present
+ *
+ * On Windows, these ACE's are processed normally, though they
+ * are redundant (as owner and group are the same), but this has
+ * no impact on administrator rights
+ *
+ * Special flags (S_ISVTX, S_ISGID, S_ISUID) :
+ * an extra null ACE is inserted to hold these flags, using
+ * the same conventions as cygwin.

+ * If not found, ntfs_attr_find() returns -1, with errno set to ENOENT and
+ * @ctx->attr will point to the attribute before which the attribute being
+ * searched for would need to be inserted if such an action were to be desired.
+ *
+ * On actual error, ntfs_attr_find() returns -1 with errno set to the error
+ * code but not to ENOENT. In this case @ctx->attr is undefined and in
+ * particular do not rely on it not changing.
+ *
+ * If @ctx->is_first is TRUE, the search begins with @ctx->attr itself. If it
+ * is FALSE, the search begins after @ctx->attr.
+ *
+ * If @type is AT_UNUSED, return the first found attribute, i.e. one can
+ * enumerate all attributes by setting @type to AT_UNUSED and then calling
+ * ntfs_attr_find() repeatedly until it returns -1 with errno set to ENOENT to
+ * indicate that there are no more entries. During the enumeration, each
+ * successful call of ntfs_attr_find() will return the next attribute in the
+ * mft record @ctx->mrec.
+ *
+ * If @type is AT_END, seek to the end and return -1 with errno set to ENOENT.
+ * AT_END is not a valid attribute, its length is zero for example, thus it is
+ * safer to return error instead of success in this case. This also allows us
+ * to interoperate cleanly with ntfs_external_attr_find().
+ *
+ * If @name is AT_UNNAMED search for an unnamed attribute. If @name is present
+ * but not AT_UNNAMED search for a named attribute matching @name. Otherwise,
+ * match both named and unnamed attributes.
+ *
+ * If @ic is IGNORE_CASE, the @name comparison is not case sensitive and
+ * @ctx->ntfs_ino must be set to the ntfs inode to which the mft record
+ * @ctx->mrec belongs. This is so we can get at the ntfs volume and hence at
+ * the upcase table. If @ic is CASE_SENSITIVE, the comparison is case
+ * sensitive. When @name is present, @name_len is the @name length in Unicode
+ * characters.
+ *
+ * If @name is not present (NULL), we assume that the unnamed attribute is

+ *
+ * Finally, the resident attribute value @val is looked for, if present.

+ *
+ * ntfs_attr_find() only searches the specified mft record and it ignores the
+ * presence of an attribute list attribute (unless it is the one being searched
+ * for, obviously). If you need to take attribute lists into consideration, use
+ * ntfs_attr_lookup() instead (see below). This also means that you cannot use
+ * ntfs_attr_find() to search for extent records of non-resident attributes, as
+ * extents with lowest_vcn != 0 are usually described by the attribute list
+ * attribute only. - Note that it is possible that the first extent is only in
+ * the attribute list while the last extent is in the base mft record, so don't
+ * rely on being able to find the first extent in the base mft record.

+ * ntfs_external_attr_find - find an attribute in the attribute list of an inode
+ * @type: attribute type to find
+ * @name: attribute name to find (optional, i.e. NULL means don't care)
+ * @name_len: attribute name length (only needed if @name present)
+ * @ic: IGNORE_CASE or CASE_SENSITIVE (ignored if @name not present)
+ * @lowest_vcn: lowest vcn to find (optional, non-resident attributes only)
+ * @val: attribute value to find (optional, resident attributes only)
+ * @val_len: attribute value length
+ * @ctx: search context with mft record and attribute to search from
+ *
+ * You shouldn't need to call this function directly. Use ntfs_attr_lookup()
+ * instead.
+ *
+ * Find an attribute by searching the attribute list for the corresponding
+ * attribute list entry. Having found the entry, map the mft record for read
+ * if the attribute is in a different mft record/inode, find the attribute in
+ * there and return it.
+ *
+ * If @type is AT_UNUSED, return the first found attribute, i.e. one can
+ * enumerate all attributes by setting @type to AT_UNUSED and then calling
+ * ntfs_external_attr_find() repeatedly until it returns -1 with errno set to
+ * ENOENT to indicate that there are no more entries. During the enumeration,
+ * each successful call of ntfs_external_attr_find() will return the next
+ * attribute described by the attribute list of the base mft record described
+ * by the search context @ctx.
+ *
+ * If @type is AT_END, seek to the end of the base mft record ignoring the
+ * attribute list completely and return -1 with errno set to ENOENT. AT_END is
+ * not a valid attribute, its length is zero for example, thus it is safer to
+ * return error instead of success in this case.
+ *
+ * If @name is AT_UNNAMED search for an unnamed attribute. If @name is present
+ * but not AT_UNNAMED search for a named attribute matching @name. Otherwise,
+ * match both named and unnamed attributes.
+ *
+ * On first search @ctx->ntfs_ino must be the inode of the base mft record and
+ * @ctx must have been obtained from a call to ntfs_attr_get_search_ctx().
+ * On subsequent calls, @ctx->ntfs_ino can be any extent inode, too
+ * (@ctx->base_ntfs_ino is then the base inode).
+ *
+ * After finishing with the attribute/mft record you need to call
+ * ntfs_attr_put_search_ctx() to cleanup the search context (unmapping any
+ * mapped extent inodes, etc).
+ *
+ * Return 0 if the search was successful and -1 if not, with errno set to the
+ * error code.
+ *
+ * On success, @ctx->attr is the found attribute, it is in mft record
+ * @ctx->mrec, and @ctx->al_entry is the attribute list entry for this
+ * attribute with @ctx->base_* being the base mft record to which @ctx->attr
+ * belongs.
+ *
+ * On error ENOENT, i.e. attribute not found, @ctx->attr is set to the
+ * attribute which collates just after the attribute being searched for in the
+ * base ntfs inode, i.e. if one wants to add the attribute to the mft record
+ * this is the correct place to insert it into, and if there is not enough
+ * space, the attribute should be placed in an extent mft record.
+ * @ctx->al_entry points to the position within @ctx->base_ntfs_ino->attr_list
+ * at which the new attribute's attribute list entry should be inserted. The
+ * other @ctx fields, base_ntfs_ino, base_mrec, and base_attr are set to NULL.
+ * The only exception to this is when @type is AT_END, in which case
+ * @ctx->al_entry is set to NULL also (see above).
+ *
+ * The following error codes are defined:
+ * ENOENT Attribute not found, not an error as such.
+ * EINVAL Invalid arguments.
+ * EIO I/O error or corrupt data structures found.
+ * ENOMEM Not enough memory to allocate necessary buffers.

+ * If the @key is not found in the index, -1 is returned, errno = ENOENT and
+ * @icx is setup to describe the index entry whose key collates immediately
+ * after the search @key, i.e. this is the position in the index at which
+ * an index entry with a key of @key would need to be inserted.
+ *
+ * If an error occurs return -1, set errno to error code and @icx is left

+ * ntfs_cluster_alloc - allocate clusters on an ntfs volume
+ * @vol: mounted ntfs volume on which to allocate the clusters
+ * @start_vcn: vcn to use for the first allocated cluster
+ * @count: number of clusters to allocate
+ * @start_lcn: starting lcn at which to allocate the clusters (or -1 if none)
+ * @zone: zone from which to allocate the clusters
+ *
+ * Allocate @count clusters preferably starting at cluster @start_lcn or at the
+ * current allocator position if @start_lcn is -1, on the mounted ntfs volume
+ * @vol. @zone is either DATA_ZONE for allocation of normal clusters and
+ * MFT_ZONE for allocation of clusters for the master file table, i.e. the
+ * $MFT/$DATA attribute.
+ *
+ * On success return a runlist describing the allocated cluster(s).
+ *
+ * On error return NULL with errno set to the error code.
+ *
+ * Notes on the allocation algorithm
+ * =================================
+ *
+ * There are two data zones. First is the area between the end of the mft zone
+ * and the end of the volume, and second is the area between the start of the
+ * volume and the start of the mft zone. On unmodified/standard NTFS 1.x
+ * volumes, the second data zone doesn't exist due to the mft zone being
+ * expanded to cover the start of the volume in order to reserve space for the
+ * mft bitmap attribute.
+ *
+ * The complexity stems from the need of implementing the mft vs data zoned
+ * approach and from the fact that we have access to the lcn bitmap via up to
+ * NTFS_LCNALLOC_BSIZE bytes at a time, so we need to cope with crossing over
+ * boundaries of two buffers. Further, the fact that the allocator allows for
+ * caller supplied hints as to the location of where allocation should begin
+ * and the fact that the allocator keeps track of where in the data zones the
+ * next natural allocation should occur, contribute to the complexity of the
+ * function. But it should all be worthwhile, because this allocator:
+ * 1) implements MFT zone reservation
+ * 2) causes reduction in fragmentation.
+ * The code is not optimized for speed.

+ * Allocate an mft record in $MFT/$DATA of an open ntfs volume @vol.
+ *
+ * If @base_ni is NULL make the mft record a base mft record and allocate it at
+ * the default allocator position.
+ *
+ * If @base_ni is not NULL make the allocated mft record an extent record,
+ * allocate it starting at the mft record after the base mft record and attach
+ * the allocated and opened ntfs inode to the base inode @base_ni.
+ *
+ * On success return the now opened ntfs (extent) inode of the mft record.
+ *
+ * On error return NULL with errno set to the error code.
+ *
+ * To find a free mft record, we scan the mft bitmap for a zero bit. To
+ * optimize this we start scanning at the place specified by @base_ni or if
+ * @base_ni is NULL we start where we last stopped and we perform wrap around
+ * when we reach the end. Note, we do not try to allocate mft records below
+ * number 24 because numbers 0 to 15 are the defined system files anyway and 16
+ * to 24 are used for storing extension mft records or used by chkdsk to store
+ * its log. However the record number 15 is dedicated to the first extent to
+ * the $DATA attribute of $MFT. This is required to avoid the possibility
+ * of creating a run list with a circular dependence which once written to disk
+ * can never be read in again. Windows will only use records 16 to 24 for
+ * normal files if the volume is completely out of space. We never use them
+ * which means that when the volume is really out of space we cannot create any
+ * more files while Windows can still create up to 8 small files. We can start
+ * doing this at some later time, it does not matter much for now.
+ *
+ * When scanning the mft bitmap, we only search up to the last allocated mft
+ * record. If there are no free records left in the range 24 to number of
+ * allocated mft records, then we extend the $MFT/$DATA attribute in order to
+ * create free mft records. We extend the allocated size of $MFT/$DATA by 16
+ * records at a time or one cluster, if cluster size is above 16kiB. If there
+ * is not sufficient space to do this, we try to extend by a single mft record
+ * or one cluster, if cluster size is above the mft record size, but we only do
+ * this if there is enough free space, which we know from the values returned
+ * by the failed cluster allocation function when we tried to do the first
+ * allocation.
+ *
+ * No matter how many mft records we allocate, we initialize only the first
+ * allocated mft record, incrementing mft data size and initialized size
+ * accordingly, open an ntfs_inode for it and return it to the caller, unless
+ * there are less than 24 mft records, in which case we allocate and initialize
+ * mft records until we reach record 24 which we consider as the first free mft
+ * record for use by normal files.
+ *
+ * If during any stage we overflow the initialized data in the mft bitmap, we
+ * extend the initialized size (and data size) by 8 bytes, allocating another
+ * cluster if required. The bitmap data size has to be at least equal to the
+ * number of mft records in the mft, but it can be bigger, in which case the
+ * superfluous bits are padded with zeroes.
+ *
+ * Thus, when we return successfully (return value non-zero), we will have:
+ * - initialized / extended the mft bitmap if necessary,
+ * - initialized / extended the mft data if necessary,
+ * - set the bit corresponding to the mft record being allocated in the
+ * mft bitmap,
+ * - open an ntfs_inode for the allocated mft record, and we will
+ * - return the ntfs_inode.
+ *
+ * On error (return value zero), nothing will have changed. If we had changed
+ * anything before the error occurred, we will have reverted back to the
+ * starting state before returning to the caller. Thus, except for bugs, we
+ * should always leave the volume in a consistent state when returning from
+ * this function.
+ *
+ * Note, this function cannot make use of most of the normal functions, like
+ * for example for attribute resizing, etc, because when the run list overflows
+ * the base mft record and an attribute list is used, it is very important that
+ * the extension mft records used to store the $DATA attribute of $MFT can be
+ * reached without having to read the information contained inside them, as
+ * this would make it impossible to find them in the first place after the
+ * volume is dismounted. $MFT/$BITMAP probably does not need to follow this
+ * rule because the bitmap is not essential for finding the mft records, but on
+ * the other hand, handling the bitmap in this special way would make life
+ * easier because otherwise there might be circular invocations of functions
+ * when reading the bitmap but if we are careful, we should be able to avoid
+ * all problems.

+ * Endianness considerations
+ *
+ * According to RFC 4122, GUIDs should be printed with the most
+ * significant byte first, and the six fields be compared individually
+ * for ordering. RFC 4122 does not define the internal representation.
+ *
+ * Here we always copy disk images with no endianness change,
+ * and, for indexing, GUIDs are compared as if they were a sequence
+ * of four unsigned 32 bit integers.
+ *
+ * --------------------- begin from RFC 4122 ----------------------
+ * Consider each field of the UUID to be an unsigned integer as shown
+ * in the table in section Section 4.1.2. Then, to compare a pair of
+ * UUIDs, arithmetically compare the corresponding fields from each
+ * UUID in order of significance and according to their data type.
+ * Two UUIDs are equal if and only if all the corresponding fields
+ * are equal.
+ *
+ * UUIDs, as defined in this document, can also be ordered
+ * lexicographically. For a pair of UUIDs, the first one follows the
+ * second if the most significant field in which the UUIDs differ is
+ * greater for the first UUID. The second precedes the first if the
+ * most significant field in which the UUIDs differ is greater for
+ * the second UUID.
+ *
+ * The fields are encoded as 16 octets, with the sizes and order of the
+ * fields defined above, and with each field encoded with the Most
+ * Significant Byte first (known as network byte order). Note that the
+ * field names, particularly for multiplexed fields, follow historical
+ * practice.

+.SH DESCRIPTION
+.B mkntfs
+is used to create an NTFS file system on a device (usually a disk partition)
+or file.
+.I device
+is the special file corresponding to the device (e.g
+.IR /dev/hdXX ).
+.I number\-of\-sectors
+is the number of sectors on the device. If omitted,
+.B mkntfs
+automagically figures the file system size.
+.SH OPTIONS
+Below is a summary of all the options that
+.B mkntfs
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.SS Basic options
+.TP
+\fB\-f\fR, \fB\-\-fast\fR, \fB\-Q\fR, \fB\-\-quick\fR
+Perform quick (fast) format. This will skip both zeroing of the volume and bad
+sector checking.
+.TP
+\fB\-L\fR, \fB\-\-label\fR STRING
+Set the volume label for the filesystem.
+.TP
+\fB\-C\fR, \fB\-\-enable\-compression\fR
+Enable compression on the volume.
+.TP
+\fB\-n\fR, \fB\-\-no\-action\fR
+Causes
+.B mkntfs
+to not actually create a filesystem, but display what it would do if it were
+to create a filesystem. All steps of the format are carried out except the
+actual writing to the device.
+.SS Advanced options
+.TP
+\fB\-c\fR, \fB\-\-cluster\-size\fR BYTES
+Specify the size of clusters in bytes. Valid cluster size values are powers of
+two, with at least 256, and at most 65536 bytes per cluster. If omitted,
+.B mkntfs
+uses 4096 bytes as the default cluster size.
+.sp
+Note that the default cluster size is set to be at least equal to the sector
+size as a cluster cannot be smaller than a sector. Also, note that values
+greater than 4096 have the side effect that compression is disabled on the
+volume (due to limitations in the NTFS compression algorithm currently in use
+by Windows).
+.TP
+\fB\-s\fR, \fB\-\-sector\-size\fR BYTES
+Specify the size of sectors in bytes. Valid sector size values are 256, 512,
+1024, 2048 and 4096 bytes per sector. If omitted,
+.B mkntfs
+attempts to determine the
+.I sector\-size
+automatically and if that fails a default of 512 bytes per sector is used.
+.TP
+\fB\-p\fR, \fB\-\-partition\-start\fR SECTOR
+Specify the partition start sector. The maximum is 4294967295 (2^32\-1). If
+omitted,
+.B mkntfs
+attempts to determine
+.I part\-start\-sect
+automatically and if that fails a default of 0 is used. Note that
+.I part\-start\-sect
+is required for Windows to be able to boot from the created volume.
+.TP
+\fB\-H\fR, \fB\-\-heads\fR NUM
+Specify the number of heads. The maximum is 65535 (0xffff). If omitted,
+.B mkntfs
+attempts to determine the number of
+.I heads
+automatically and if that fails a default of 0 is used. Note that
+.I heads
+is required for Windows to be able to boot from the created volume.
+.TP
+\fB\-S\fR, \fB\-\-sectors\-per\-track\fR NUM
+Specify the number of sectors per track. The maximum is 65535 (0xffff). If
+omitted,
+.B mkntfs
+attempts to determine the number of
+.I sectors\-per\-track
+automatically and if that fails a default of 0 is used. Note that
+.I sectors\-per\-track
+is required for Windows to be able to boot from the created volume.
+.TP
+\fB\-z\fR, \fB\-\-mft\-zone\-multiplier\fR NUM
+Set the MFT zone multiplier, which determines the size of the MFT zone to use
+on the volume. The MFT zone is the area at the beginning of the volume reserved
+for the master file table (MFT), which stores the on disk inodes (MFT records).
+It is noteworthy that small files are stored entirely within the inode;
+thus, if you expect to use the volume for storing large numbers of very small
+files, it is useful to set the zone multiplier to a higher value. Note, that
+the MFT zone is resized on the fly as required during operation of the NTFS
+driver but choosing a good value will reduce fragmentation. Valid values
+are 1, 2, 3 and 4. The values have the following meaning:
+.TS
+box;
+lB lB
+lB lB
+c l.
+MFT zone MFT zone size
+multiplier (% of volume size)
+1 12.5% (default)
+2 25.0%
+3 37.5%
+4 50.0%
+.TE
+.sp
+.TP
+\fB\-T\fR, \fB\-\-zero\-time\fR
+Fake the time to be 00:00:00 UTC, Jan 1, 1970 instead of the current system
+time. This is only really useful for debugging purposes.
+.TP
+\fB\-U\fR, \fB\-\-with\-uuid\fR
+Generate a random volume UUID.
+.TP
+\fB\-I\fR, \fB\-\-no\-indexing\fR
+Disable content indexing on the volume. (This is only meaningful on
+Windows 2000 and later. Windows NT 4.0 and earlier ignore this as they do
+not implement content indexing at all.)
+.TP
+\fB\-F\fR, \fB\-\-force\fR
+Force
+.B mkntfs
+to run, even if the specified
+.I device
+is not a block special device, or appears to be mounted.
+.SS Output options
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Quiet execution; only errors are written to stderr, no output to stdout
+occurs at all. Useful if
+.B mkntfs
+is run in a script.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+Verbose execution.
+.TP
+\fB\-\-debug\fR
+Really verbose execution; includes the verbose output from the
+.B \-v
+option as well as additional output useful for debugging
+.B mkntfs.
+.SS Help options
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Print the version number of
+.B mkntfs
+and exit.
+.TP
+\fB\-l\fR, \fB\-\-license\fR
+Print the licensing information of
+.B mkntfs
+and exit.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Show a list of options with a brief description of each one.
+.SH KNOWN ISSUES
+When applying chkdsk to a file system, it sometimes throws a warning
+"Correcting errors in the uppercase file." The uppercase file is created
+while formatting and it defines the mapping of lower case characters to
+upper case ones, as needed to sort file names in directories. The warning
+means that the uppercase file defined on the file system is not the same as
+the one used by the Windows OS on which chkdsk is running, and this may
+happen because newer versions of Windows take into account new characters
+defined by the Unicode consortium.
+.P
+Currently, mkntfs creates the uppercase table so that no warning is thrown
+by Windows Vista, Windows 7 or Windows 8. A warning may be thrown by
+other Windows versions, or if chkdsk is applied in succession on different
+Windows versions.

+ * You shouldn't need to call this function directly. Use lookup_attr() instead.
+ *

+ * attribute of @type, optionally @name and @val. If found, ntfs_attr_find()
+ * returns 0 and @ctx->attr will point to the found attribute.
+ *
+ * If not found, ntfs_attr_find() returns -1, with errno set to ENOENT and
+ * @ctx->attr will point to the attribute before which the attribute being
+ * searched for would need to be inserted if such an action were to be desired.
+ *
+ * On actual error, ntfs_attr_find() returns -1 with errno set to the error
+ * code but not to ENOENT. In this case @ctx->attr is undefined and in
+ * particular do not rely on it not changing.
+ *
+ * If @ctx->is_first is TRUE, the search begins with @ctx->attr itself. If it
+ * is FALSE, the search begins after @ctx->attr.
+ *
+ * If @type is AT_UNUSED, return the first found attribute, i.e. one can
+ * enumerate all attributes by setting @type to AT_UNUSED and then calling
+ * ntfs_attr_find() repeatedly until it returns -1 with errno set to ENOENT to
+ * indicate that there are no more entries. During the enumeration, each
+ * successful call of ntfs_attr_find() will return the next attribute in the
+ * mft record @ctx->mrec.
+ *
+ * If @type is AT_END, seek to the end and return -1 with errno set to ENOENT.
+ * AT_END is not a valid attribute, its length is zero for example, thus it is
+ * safer to return error instead of success in this case. This also allows us
+ * to interoperate cleanly with ntfs_external_attr_find().
+ *
+ * If @name is AT_UNNAMED search for an unnamed attribute. If @name is present
+ * but not AT_UNNAMED search for a named attribute matching @name. Otherwise,
+ * match both named and unnamed attributes.
+ *
+ * If @ic is IGNORE_CASE, the @name comparison is not case sensitive and
+ * @ctx->ntfs_ino must be set to the ntfs inode to which the mft record
+ * @ctx->mrec belongs. This is so we can get at the ntfs volume and hence at
+ * the upcase table. If @ic is CASE_SENSITIVE, the comparison is case
+ * sensitive. When @name is present, @name_len is the @name length in Unicode
+ * characters.
+ *
+ * If @name is not present (NULL), we assume that the unnamed attribute is
+ * being searched for.
+ *
+ * Finally, the resident attribute value @val is looked for, if present.
+ * If @val is not present (NULL), @val_len is ignored.
+ *

+ * presence of an attribute list attribute (unless it is the one being searched
+ * for, obviously). If you need to take attribute lists into consideration, use
+ * ntfs_attr_lookup() instead (see below). This also means that you cannot use
+ * ntfs_attr_find() to search for extent records of non-resident attributes, as
+ * extents with lowest_vcn != 0 are usually described by the attribute list
+ * attribute only. - Note that it is possible that the first extent is only in
+ * the attribute list while the last extent is in the base mft record, so don't
+ * rely on being able to find the first extent in the base mft record.

+ntfsclone \- Efficiently clone, image, restore or rescue an NTFS
+.SH SYNOPSIS
+.B ntfsclone

+.I SOURCE
+.br
+.B ntfsclone \-\-save\-image

+.SH DESCRIPTION
+.B ntfsclone
+will efficiently clone (copy, save, backup, restore) or rescue an NTFS
+filesystem to a sparse file, image, device (partition) or standard output.
+It works at disk sector level and
+copies only the used data. Unused disk space becomes zero (cloning to
+sparse file), encoded with control codes (saving in special image format),
+left unchanged (cloning to a disk/partition) or
+filled with zeros (cloning to standard output).
+
+.B ntfsclone
+can be useful to make backups, an exact snapshot of an NTFS filesystem
+and restore it later on, or for developers to test NTFS read/write
+functionality, troubleshoot/investigate users' issues using the clone
+without the risk of destroying the original filesystem.
+
+The clone, if not using the special image format, is an exact copy of the
+original NTFS filesystem from sector to sector thus it can be also mounted
+just like the original NTFS filesystem.
+For example if you clone to a file and the kernel has loopback device and
+NTFS support then the file can be mounted as
+.RS
+.sp
+.B mount \-t ntfs \-o loop ntfsclone.img /mnt/ntfsclone
+.sp
+.RE
+.SS Windows Cloning
+If you want to copy, move or restore a system or boot partition to another
+computer, or to a different disk or partition (e.g. hda1\->hda2, hda1\->hdb1
+or to a different disk sector offset) then you will need to take extra care.
+
+Usually, Windows will not be able to boot, unless you copy, move or restore
+NTFS to the same partition which starts at the same sector on the same type
+of disk having the same BIOS legacy cylinder setting as the original
+partition and disk had.
+
+The ntfsclone utility guarantees to make an exact copy of NTFS but it
+won't deal with booting issues. This is by design: ntfsclone is a
+filesystem, not system utility. Its aim is only NTFS cloning, not Windows
+cloning. Hereby ntfsclone can be used as a very fast and reliable
+build block for Windows cloning but itself it's not enough.
+.SS Sparse Files
+A file is sparse if it has unallocated blocks (holes). The reported size of
+such files are always higher than the disk space consumed by them. The
+.BR du
+command can tell the real disk space used by a sparse file.
+The holes are always read as zeros. All major Linux filesystem like,
+ext2, ext3, reiserfs, Reiser4, JFS and XFS, supports
+sparse files but for example the ISO 9600 CD\-ROM filesystem doesn't.
+.SS Handling Large Sparse Files
+As of today Linux provides inadequate support for managing (tar,
+cp, gzip, gunzip, bzip2, bunzip2, cat, etc) large sparse files.
+The only main Linux filesystem
+having support for efficient sparse file handling is XFS by the
+XFS_IOC_GETBMAPX
+.BR ioctl (2) .
+However none of the common utilities supports it.
+This means when you tar, cp, gzip, bzip2, etc a large sparse file
+they will always read the entire file, even if you use the "sparse support"
+options.
+
+.BR bzip2 (1)
+compresses large sparse files much better than
+.BR gzip (1)
+but it does so
+also much slower. Moreover neither of them handles large sparse
+files efficiently during uncompression from disk space usage point
+of view.
+
+At present the most efficient way, both speed and space\-wise, to
+compress and uncompress large sparse files by common tools
+would be using
+.BR tar (1)
+with the options
+.B \-S
+(handle sparse files "efficiently") and
+.B \-j
+(filter the archive through bzip2). Although
+.BR tar
+still reads and analyses the entire file, it doesn't pass on the
+large data blocks having only zeros to filters and it also avoids
+writing large amount of zeros to the disk needlessly. But since
+.BR tar
+can't create an archive from the standard input, you can't do this
+in\-place by just reading
+.BR ntfsclone
+standard output. Even more sadly, using the \-S option results
+serious data loss since the end of 2004 and the GNU
+.BR tar
+maintainers didn't release fixed versions until the present day.
+.SS The Special Image Format
+It's also possible, actually it's recommended, to save an NTFS filesystem
+to a special image format.
+Instead of representing unallocated blocks as holes, they are
+encoded using control codes. Thus, the image saves space without
+requiring sparse file support. The image format is ideal for streaming
+filesystem images over the network and similar, and can be used as a
+replacement for Ghost or Partition Image if it is combined with other
+tools. The downside is that you can't mount the image directly, you
+need to restore it first.
+
+To save an image using the special image format, use the
+.B \-s
+or the
+.B \-\-save\-image
+option. To restore an image, use the
+.B \-r
+or the
+.B \-\-restore\-image
+option. Note that you can restore images from standard input by
+using '\-' as the
+.I SOURCE
+file.
+.SS Metadata\-only Cloning
+One of the features of
+.BR ntfsclone
+is that, it can also save only the NTFS metadata using the option
+.B \-m
+or
+.B \-\-metadata
+and the clone still will be
+mountable. In this case all non\-metadata file content will be lost and
+reading them back will result always zeros.
+
+The metadata\-only image can be compressed very
+well, usually to not more than 1\-8 MB thus it's easy to transfer
+for investigation, troubleshooting.
+
+In this mode of ntfsclone,
+.B NONE
+of the user's data is saved, including the resident user's data
+embedded into metadata. All is filled with zeros.
+Moreover all the file timestamps, deleted and unused spaces inside
+the metadata are filled with zeros. Thus this mode is inappropriate
+for example for forensic analyses.
+This mode may be combined with \fB\-\-save\-image\fP to create a
+special image format file instead of a sparse file.
+
+Please note, filenames are not wiped out. They might contain
+sensitive information, so think twice before sending such an
+image to anybody.
+.SH OPTIONS

+.SH DESCRIPTION
+.B ntfsclone
+will efficiently clone (copy, save, backup, restore) or rescue an NTFS
+filesystem to a sparse file, image, device (partition) or standard output.
+It works at disk sector level and
+copies only the used data. Unused disk space becomes zero (cloning to
+sparse file), encoded with control codes (saving in special image format),
+left unchanged (cloning to a disk/partition) or
+filled with zeros (cloning to standard output).
+
+.B ntfsclone
+can be useful to make backups, an exact snapshot of an NTFS filesystem
+and restore it later on, or for developers to test NTFS read/write
+functionality, troubleshoot/investigate users' issues using the clone
+without the risk of destroying the original filesystem.
+
+The clone, if not using the special image format, is an exact copy of the
+original NTFS filesystem from sector to sector thus it can be also mounted
+just like the original NTFS filesystem.
+For example if you clone to a file and the kernel has loopback device and
+NTFS support then the file can be mounted as
+.RS
+.sp
+.B mount \-t ntfs \-o loop ntfsclone.img /mnt/ntfsclone
+.sp
+.RE
+.SS Windows Cloning
+If you want to copy, move or restore a system or boot partition to another
+computer, or to a different disk or partition (e.g. hda1\->hda2, hda1\->hdb1
+or to a different disk sector offset) then you will need to take extra care.
+
+Usually, Windows will not be able to boot, unless you copy, move or restore
+NTFS to the same partition which starts at the same sector on the same type
+of disk having the same BIOS legacy cylinder setting as the original
+partition and disk had.
+
+The ntfsclone utility guarantees to make an exact copy of NTFS but it
+won't deal with booting issues. This is by design: ntfsclone is a
+filesystem, not system utility. Its aim is only NTFS cloning, not Windows
+cloning. Hereby ntfsclone can be used as a very fast and reliable
+build block for Windows cloning but itself it's not enough.
+.SS Sparse Files
+A file is sparse if it has unallocated blocks (holes). The reported size of
+such files are always higher than the disk space consumed by them. The
+.BR du
+command can tell the real disk space used by a sparse file.
+The holes are always read as zeros. All major Linux filesystem like,
+ext2, ext3, reiserfs, Reiser4, JFS and XFS, supports
+sparse files but for example the ISO 9600 CD\-ROM filesystem doesn't.
+.SS Handling Large Sparse Files
+As of today Linux provides inadequate support for managing (tar,
+cp, gzip, gunzip, bzip2, bunzip2, cat, etc) large sparse files.
+The only main Linux filesystem
+having support for efficient sparse file handling is XFS by the
+XFS_IOC_GETBMAPX
+.BR ioctl (2) .
+However none of the common utilities supports it.
+This means when you tar, cp, gzip, bzip2, etc a large sparse file
+they will always read the entire file, even if you use the "sparse support"
+options.
+
+.BR bzip2 (1)
+compresses large sparse files much better than
+.BR gzip (1)
+but it does so
+also much slower. Moreover neither of them handles large sparse
+files efficiently during uncompression from disk space usage point
+of view.
+
+At present the most efficient way, both speed and space\-wise, to
+compress and uncompress large sparse files by common tools
+would be using
+.BR tar (1)
+with the options
+.B \-S
+(handle sparse files "efficiently") and
+.B \-j
+(filter the archive through bzip2). Although
+.BR tar
+still reads and analyses the entire file, it doesn't pass on the
+large data blocks having only zeros to filters and it also avoids
+writing large amount of zeros to the disk needlessly. But since
+.BR tar
+can't create an archive from the standard input, you can't do this
+in\-place by just reading
+.BR ntfsclone
+standard output. Even more sadly, using the \-S option results
+serious data loss since the end of 2004 and the GNU
+.BR tar
+maintainers didn't release fixed versions until the present day.
+.SS The Special Image Format
+It's also possible, actually it's recommended, to save an NTFS filesystem
+to a special image format.
+Instead of representing unallocated blocks as holes, they are
+encoded using control codes. Thus, the image saves space without
+requiring sparse file support. The image format is ideal for streaming
+filesystem images over the network and similar, and can be used as a
+replacement for Ghost or Partition Image if it is combined with other
+tools. The downside is that you can't mount the image directly, you
+need to restore it first.
+
+To save an image using the special image format, use the
+.B \-s
+or the
+.B \-\-save\-image
+option. To restore an image, use the
+.B \-r
+or the
+.B \-\-restore\-image
+option. Note that you can restore images from standard input by
+using '\-' as the
+.I SOURCE
+file.
+.SS Metadata\-only Cloning
+One of the features of
+.BR ntfsclone
+is that, it can also save only the NTFS metadata using the option
+.B \-m
+or
+.B \-\-metadata
+and the clone still will be
+mountable. In this case all non\-metadata file content will be lost and
+reading them back will result always zeros.
+
+The metadata\-only image can be compressed very
+well, usually to not more than 1\-8 MB thus it's easy to transfer
+for investigation, troubleshooting.
+
+In this mode of ntfsclone,
+.B NONE
+of the user's data is saved, including the resident user's data
+embedded into metadata. All is filled with zeros.
+Moreover all the file timestamps, deleted and unused spaces inside
+the metadata are filled with zeros. Thus this mode is inappropriate
+for example for forensic analyses.
+This mode may be combined with \fB\-\-save\-image\fP to create a
+special image format file instead of a sparse file.
+
+Please note, filenames are not wiped out. They might contain
+sensitive information, so think twice before sending such an
+image to anybody.
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfsclone
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by

+.SS Info
+.PP
+The default mode,

+.SH NAME
+ntfscmp \- compare two NTFS filesystems and tell the differences
+.SH SYNOPSIS
+.B ntfscmp
+[\fIOPTIONS\fR]
+.I DEVICE1
+.I DEVICE2
+.br
+.SH DESCRIPTION
+The
+.B ntfscmp
+program makes a comparison between two NTFS filesystems from all aspects and
+reports all variances it finds.
+The filesystems can be on block devices or images files. Ntfscmp can be used
+for volume verification however its primary purpose was to be an efficient
+development tool, used to quickly locate, identify and check the correctness
+of the metadata changes made to NTFS.
+
+If one is interested only in the NTFS metadata changes then it could be useful

+.TH NTFSCMP 8 "April 2006" "ntfs-3g @VERSION@"
+.SH NAME
+ntfscmp \- compare two NTFS filesystems and tell the differences
+.SH SYNOPSIS
+.B ntfscmp
+[\fIOPTIONS\fR]
+.I DEVICE1
+.I DEVICE2
+.br
+.SH DESCRIPTION
+The
+.B ntfscmp
+program makes a comparison between two NTFS filesystems from all aspects and
+reports all variances it finds.
+The filesystems can be on block devices or images files. Ntfscmp can be used
+for volume verification however its primary purpose was to be an efficient
+development tool, used to quickly locate, identify and check the correctness
+of the metadata changes made to NTFS.
+
+If one is interested only in the NTFS metadata changes then it could be useful
+to compare the metadata images created by
+using the --metadata option of
+.BR ntfsclone (8)
+to eliminate the usually uninteresting timestamp changes.
+
+The terse output of
+.B ntfscmp
+is intentional because the provided information is enough in each case
+to determine the exact differences. This can be achieved, for instance,
+if one compares the verbose outputs of
+.BR ntfsinfo (8)
+for each reported inodes by the
+.BR diff (1)
+utility.

+.SH NAME
+ntfscp \- copy file to an NTFS volume.
+.SH SYNOPSIS
+\fBntfscp\fR [\fIoptions\fR] \fIdevice source_file destination\fR
+.SH DESCRIPTION
+\fBntfscp\fR will copy file to an NTFS volume. \fIdestination\fR can be either
+file or directory. In case if \fIdestination\fR is directory specified by name
+then \fIsource_file\fR is copied into this directory, in case if
+\fIdestination\fR is directory and specified by inode number then unnamed data
+attribute is created for this inode and \fIsource_file\fR is copied into it
+(WARNING: it's unusual to have unnamed data streams in the directories, think
+twice before specifying directory by inode number).
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfscp
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-a\fR, \fB\-\-attribute\fR NUM
+Write to this attribute.
+.TP
+\fB\-i\fR, \fB\-\-inode\fR
+Treat
+.I destination
+as inode number.

+.TP
+\fB\-N\fR, \fB\-\-attr\-name\fR NAME
+Write to attribute with this name.
+.TP
+\fB\-n\fR, \fB\-\-no\-action\fR
+Use this option to make a test run before doing the real copy operation.
+Volume will be opened read\-only and no write will be done.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+This will override some sensible defaults, such as not working with a mounted
+volume. Use this option with caution.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Show a list of options with a brief description of each one.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Suppress some debug/warning/error messages.

+Show the version number, copyright and license
+.BR ntfscp .
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+Display more debug/warning/error messages.
+.SH DATA STREAMS
+All data on NTFS is stored in streams, which can have names. A file can have
+more than one data streams, but exactly one must have no name. The size of a
+file is the size of its unnamed data stream. Usually when you don't specify
+stream name you are access to unnamed data stream. If you want access to named
+data stream you need to add ":stream_name" to the filename. For example: by
+opening "some.mp3:artist" you will open stream "artist" in "some.mp3". But
+windows usually prevent you from accessing to named data streams, so you need
+to use some program like FAR or utils from cygwin to access named data streams.
+.SH EXAMPLES
+Copy new_boot.ini from /home/user as boot.ini to the root of an /dev/hda1 NTFS
+volume:
+.RS
+.sp
+.B ntfscp /dev/hda1 /home/user/new_boot.ini boot.ini
+.sp
+.RE
+Copy myfile to C:\\some\\path\\myfile:stream (assume that /dev/hda1 letter in
+windows is C):
+.RS
+.sp
+.B ntfscp \-N stream /dev/hda1 myfile /some/path

+.SH NAME
+ntfsdecrypt \- decrypt or update NTFS files encrypted according to EFS
+.SH SYNOPSIS
+\fBntfsdecrypt\fR [\fIoptions\fR] -k \fIkey.pfx \fIdevice file\fR
+.SH DESCRIPTION
+.B ntfsdecrypt
+decrypts a file from an unmounted device and print the decrypted data
+on the standard output.
+It can also update an encrypted file with the encryption key unchanged.
+.PP
+The NTFS file encryption (known as EFS) uses a two-level encryption :
+first, the file contents is encrypted with a random symmetric key, then
+this symmetric key is encrypted with the public keys of each of the users
+allowed to decrypt the file (RSA public key encryptions).
+.P
+Three symmetric encryption modes are currently implemented in ntfsdecrypt :
+DESX (a DES variant), 3DES (triple DES) and AES_256 (an AES variant).
+.P
+All the encrypted symmetric keys are stored along with the file in a
+special extended attribute named "$LOGGED_UTILITY_STREAM".
+Usually, at least two users are allowed to read the file : its owner and
+the recovery manager who is able to decrypt all the files in a company.
+When backing up an encrypted file, it is important to also backup the
+corresponding $LOGGED_UTILITY_STREAM, otherwise the file cannot be
+decrypted, even by the recovery manager. Also note that encrypted files
+are slightly bigger than apparent, and the option "efs_raw" has
+to be used when backing up encrypted files with ntfs-3g.
+.P
+When ntfsdecrypt is used to update a file, the keys and the
+$LOGGED_UTILITY_STREAM are kept unchanged, so a single key file has to
+be designated.
+.P
+Note : the EFS encryption is only available in professional versions
+of Windows;
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfsdecrypt
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.

+\fB\-i\fR, \fB\-\-inode\fR NUM
+Display or update the contents of a file designated through its inode number
+instead of its name.
+.TP
+\fB\-e\fR, \fB\-\-encrypt\fR
+Update an existing encrypted file and get the new contents from the
+standard input. The full public and private key file has to be designated,
+as the symmetric key is kept unchanged, so the private key is needed to
+extract it.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+This will override some sensible defaults, such as not using a mounted volume.
+Use this option with caution.
+.TP
+\fB\-k\fR, \fB\-\-keyfile\-name\fR key.pfx
+Define the file which contains the public and private keys in PKCS#12 format.
+This file obviously contains the keys of one of the users allowed to decrypt
+or update the file. It has to be extracted from Windows in PKCS#12 format
+(its usual suffix is .p12 or .pfx), and it is protected by a passphrase
+which has to be typed in for the keys to be extracted. This can be the
+key file of any user allowed to read the file, including the one of the
+recovery manager.

+.TH NTFSFALLOCATE 8 "June 2014" "ntfs-3g 2015.3.14"
+.SH NAME
+ntfsfallocate \- preallocate space to a file on an NTFS volume
+.SH SYNOPSIS
+\fBntfsfallocate\fR [\fIoptions\fR] -l \fIlength\fR \fIdevice\fR \fIfile\fR \fI[attr-type\fR [\fIattr-name\fR]]
+.SH DESCRIPTION
+.B ntfsfallocate
+preallocates space for any attribute of a file or directory, thus reserving
+space before actual contents is written. This is similar to fallocate(1).
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfsfallocate
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+This will override some sensible defaults, such as not using a mounted volume.
+Use this option with caution.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Show a list of options with a brief description of each one.
+.TP
+\fB\-l\fR, \fB\-\-length\fR LENGTH
+This is a mandatory option to specify the number of bytes to preallocate.
+It will be rounded up to a multiple of the cluster size.
+A suffix of K, M, G, T, P or E may be appended to
+mean a multiplicative factor of a power of 1000. Similarly a suffix of
+Ki, Mi, Gi, Ti, Pi or Ei may be appended to mean a multiplicative factor
+of a power of 1024.
+.TP
+\fB\-n\fR, \fB\-\-no-size-change\fR
+Do not change the apparent size of the file. The space allocated beyond
+the apparent size is not zeroed, but subsequent writing beyond the apparent
+end of file will force zeroing the inner allocated space as it cannot be
+considered as a hole any more, and this may take significant time.
+.TP
+\fB\-N\fR, \fB\-\-no-action\fR
+Simulate the allocation without actually write to device.
+.TP
+\fB\-o\fR, \fB\-\-offset\fR OFFSET
+Specify the offset in the file where preallocation starts. By default,
+the preallocation is counted from the beginning of the file. Space already
+allocated in the area defined by offset and length is preserved.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Suppress some debug/warning/error messages.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+Display more debug/warning/error messages.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Show the version number, copyright and license of
+.BR ntfsfallocate .
+.TP
+\fBattr-type\fR
+Define a particular attribute type to be preallocated (advanced use only).
+By default, the unnamed $DATA attribute (the contents of a plain file) will
+be preallocated. The attribute has to be specified by a number in decimal
+or hexadecimal :
+.TS

+.TH NTFSFIX 8 "January 2013" "ntfs-3g 2015.3.14"
+.SH NAME
+ntfsfix \- fix common errors and force Windows to check NTFS
+.SH SYNOPSIS
+.B ntfsfix
+[\fIoptions\fR] \fIdevice\fR
+.SH DESCRIPTION
+.B ntfsfix
+is a utility that fixes some common NTFS problems.
+.B ntfsfix
+is
+.B NOT
+a Linux version of chkdsk. It only repairs some fundamental NTFS
+inconsistencies, resets the NTFS journal file and schedules an NTFS consistency
+check for the first boot into Windows.
+.sp
+You may run
+.B ntfsfix
+on an NTFS volume if you think it was damaged by Windows or some other way
+and it cannot be mounted.
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfsfix
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-b\fR, \fB\-\-clear\-bad\-sectors\fR
+Clear the list of bad sectors. This is useful after cloning an old disk
+with bad sectors to a new disk.
+.TP
+\fB\-d\fR, \fB\-\-clear\-dirty\fR
+Clear the volume dirty flag if the volume can be fixed and mounted.
+If the option is not present or the volume cannot be fixed, the dirty
+volume flag is set to request a volume checking at next mount.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Show a list of options with a brief description of each one.
+.TP
+\fB\-n\fR, \fB\-\-no\-action\fR
+Do not write anything, just show what would have been done.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Show the version number, copyright and license

+ *
+ * This situation is very rare, but it was fun to fix it.
+ *
+ * The corrupted condition is :
+ * - MFT entry 0 has only the runlist for MFT entries 0-15
+ * - The attribute list for MFT shows the second part
+ * in an MFT record beyond 15
+ * Of course, this record has to be read in order to know where it is.
+ *
+ * Sample case, met in 2011 (Windows XP) :
+ * MFT record 0 has : stdinfo, nonres attrlist, the first
+ * part of MFT data (entries 0-15), and bitmap
+ * MFT record 16 has the name
+ * MFT record 17 has the third part of MFT data (16-117731)
+ * MFT record 18 has the second part of MFT data (117732-170908)
+ *
+ * Assuming the second part of the MFT is contiguous to the first
+ * part, we can find it, and fix the condition by relocating it
+ * and swapping it with MFT record 15.
+ * This record number 15 appears to be hardcoded into Windows NTFS.
+ *
+ * Only low-level library functions can be used.

+.SH NAME
+ntfslabel \- display/change the label on an ntfs file system
+.SH SYNOPSIS
+.B ntfslabel
+[\fIoptions\fR] \fIdevice \fR[\fInew\-label\fR]
+.SH DESCRIPTION
+.B ntfslabel
+will display or change the file system label on the ntfs file system located on
+.IR device .
+It can also change the serial number of the
+.IR device .
+.PP
+If the optional argument
+.I new\-label
+is not present, and no option is present,
+.B ntfslabel
+will simply display the current file system label.
+.PP
+If the optional argument
+.I new\-label
+is present, then
+.B ntfslabel
+will set the file system label to be
+.IR new\-label .
+NTFS file system labels can be at most 128 Unicode characters long; if
+.I new\-label
+is longer than 128 Unicode characters,
+.B ntfslabel
+will truncate it and print a warning message.
+.PP
+It is also possible to set the file system label using the
+.B \-L
+option of
+.BR mkntfs (8)
+during creation of the file system.
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfslabel
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+This will override some sensible defaults, such as not working with a mounted
+volume. Use this option with caution.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Show a list of options with a brief description of each one.
+.TP
+\fB\-\-new\-serial\fR[\fI=ssssssssssssssss\fR], or
+.TP
+\fB\-\-new\-half\-serial\fR[\fI=ssssssss\fR]
+Set a new serial number to the device, either the argument value, or a random
+one if no argument is given. The serial number is a 64 bit number,
+represented as a sixteen-digit hexadecimal number, used to identify the
+device during the mounting process. As a consequence, two devices with the
+same serial number cannot be mounted at the same time on the same computer.
+This is not the volume UUID used by Windows to locate files which have been
+moved to another volume.
+
+The option \-\-new\-half\-serial only changes the upper part of the serial
+number, keeping the lower part which is used by Windows unchanged.
+In this case the optional argument is an eight-digit hexadecimal number.
+
+.TP
+\fB\-n\fR, \fB\-\-no\-action\fR
+Don't actually write to disk.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Reduce the amount of output to a minimum.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+Increase the amount of output that
+.B ntfslabel
+prints. The label and the serial number are displayed.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Show the version number, copyright and license for
+.BR ntfslabel .
+.SH BUGS
+There are no known problems with
+.BR ntfslabel .

+development team:

+.SH NAME
+ntfslabel \- display/change the label on an ntfs file system
+.SH SYNOPSIS
+.B ntfslabel
+[\fIoptions\fR] \fIdevice \fR[\fInew\-label\fR]
+.SH DESCRIPTION
+.B ntfslabel
+will display or change the file system label on the ntfs file system located on
+.IR device .
+It can also change the serial number of the
+.IR device .
+.PP
+If the optional argument
+.I new\-label
+is not present, and no option is present,
+.B ntfslabel
+will simply display the current file system label.
+.PP
+If the optional argument
+.I new\-label
+is present, then
+.B ntfslabel
+will set the file system label to be
+.IR new\-label .
+NTFS file system labels can be at most 128 Unicode characters long; if
+.I new\-label
+is longer than 128 Unicode characters,
+.B ntfslabel
+will truncate it and print a warning message.
+.PP
+It is also possible to set the file system label using the
+.B \-L
+option of
+.BR mkntfs (8)
+during creation of the file system.
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfslabel
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+This will override some sensible defaults, such as not working with a mounted
+volume. Use this option with caution.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Show a list of options with a brief description of each one.
+.TP
+\fB\-\-new\-serial\fR[\fI=ssssssssssssssss\fR], or
+.TP
+\fB\-\-new\-half\-serial\fR[\fI=ssssssss\fR]
+Set a new serial number to the device, either the argument value, or a random
+one if no argument is given. The serial number is a 64 bit number,
+represented as a sixteen-digit hexadecimal number, used to identify the
+device during the mounting process. As a consequence, two devices with the
+same serial number cannot be mounted at the same time on the same computer.
+This is not the volume UUID used by Windows to locate files which have been
+moved to another volume.
+
+The option \-\-new\-half\-serial only changes the upper part of the serial
+number, keeping the lower part which is used by Windows unchanged.
+In this case the optional argument is an eight-digit hexadecimal number.
+
+.TP
+\fB\-n\fR, \fB\-\-no\-action\fR
+Don't actually write to disk.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Reduce the amount of output to a minimum.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+Increase the amount of output that
+.B ntfslabel
+prints. The label and the serial number are displayed.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Show the version number, copyright and license for
+.BR ntfslabel .
+.SH BUGS
+There are no known problems with
+.BR ntfslabel .
+If you find a bug please send an email describing the problem to the
+development team:

+.I device
+.SH DESCRIPTION
+.B ntfsls
+is used to list information about the files specified by the
+.I PATH
+option (the root directory by default).
+.I DEVICE
+is the special file corresponding to the device (e.g
+.IR /dev/hdXX )
+or an NTFS image file.
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfsls
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-a\fR, \fB\-\-all\fR
+Display all files. If this option is not specified file names in the POSIX
+namespace will not be displayed.
+.TP
+\fB\-F\fR, \fB\-\-classify\fR
+Append indicator (one of */=@|) to entries.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+Force execution. For example necessary to run on an NTFS partition stored in
+a normal file.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Print the usage information of
+.B ntfsls
+and exit.
+.TP
+\fB\-i\fR, \fB\-\-inode\fR
+Print inode number of each file. This is the MFT reference number in NTFS
+terminology.
+.TP
+\fB\-l\fR, \fB\-\-long\fR
+Use a long listing format.
+.TP
+\fB\-p\fR, \fB\-\-path\fR PATH
+The directory whose contents to list or the file (including the path) about
+which to display information.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Suppress some debug/warning/error messages.
+.TP
+\fB\-R\fR, \fB\-\-recursive\fR
+Show the contents of all directories beneath the specified directory.
+.TP
+\fB\-s\fR, \fB\-\-system\fR
+Unless this options is specified, all files beginning with a dollar sign
+character will not be listed as these files are usually system files.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+Display more debug/warning/error messages.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Print the version number of
+.B ntfsls
+and exit.
+.TP
+\fB\-x\fR, \fB\-\-dos\fR
+Display short file names, i.e. files in the DOS namespace, instead of long
+file names, i.e. files in the WIN32 namespace.

+.I device
+.SH DESCRIPTION
+.B ntfsls
+is used to list information about the files specified by the
+.I PATH
+option (the root directory by default).
+.I DEVICE
+is the special file corresponding to the device (e.g
+.IR /dev/hdXX )
+or an NTFS image file.
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfsls
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-a\fR, \fB\-\-all\fR
+Display all files. If this option is not specified file names in the POSIX
+namespace will not be displayed.
+.TP
+\fB\-F\fR, \fB\-\-classify\fR
+Append indicator (one of */=@|) to entries.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+Force execution. For example necessary to run on an NTFS partition stored in
+a normal file.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Print the usage information of
+.B ntfsls
+and exit.
+.TP
+\fB\-i\fR, \fB\-\-inode\fR
+Print inode number of each file. This is the MFT reference number in NTFS
+terminology.
+.TP
+\fB\-l\fR, \fB\-\-long\fR
+Use a long listing format.
+.TP
+\fB\-p\fR, \fB\-\-path\fR PATH
+The directory whose contents to list or the file (including the path) about
+which to display information.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Suppress some debug/warning/error messages.
+.TP
+\fB\-R\fR, \fB\-\-recursive\fR
+Show the contents of all directories beneath the specified directory.
+.TP
+\fB\-s\fR, \fB\-\-system\fR
+Unless this options is specified, all files beginning with a dollar sign
+character will not be listed as these files are usually system files.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+Display more debug/warning/error messages.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Print the version number of
+.B ntfsls
+and exit.
+.TP
+\fB\-x\fR, \fB\-\-dos\fR
+Display short file names, i.e. files in the DOS namespace, instead of long
+file names, i.e. files in the WIN32 namespace.

+.SH NAME
+ntfsresize \- resize an NTFS filesystem without data loss
+.SH SYNOPSIS
+.B ntfsresize
+[\fIOPTIONS\fR]
+.B \-\-info(\-mb\-only)
+.I DEVICE
+.br
+.B ntfsresize
+[\fIOPTIONS\fR]
+[\fB\-\-size \fISIZE\fR[\fBk\fR|\fBM\fR|\fBG\fR]]
+.I DEVICE
+.SH DESCRIPTION
+The
+.B ntfsresize
+program safely resizes Windows XP, Windows Server 2003, Windows 2000, Windows
+NT4 and Longhorn NTFS filesystems without data loss. All NTFS versions are
+supported, used by 32\-bit and 64\-bit Windows.
+.B Defragmentation is NOT required prior to resizing
+because the program can relocate any data if needed, without risking data
+integrity.
+.PP
+Ntfsresize can be used to shrink or enlarge any NTFS filesystem located
+on an unmounted
+.I DEVICE
+(usually a disk partition). The new filesystem will fit in a DEVICE
+whose desired size is
+.I SIZE
+bytes.
+The
+.I SIZE
+parameter may have one of the optional modifiers
+.BR k ,
+.BR M ,
+.BR G ,
+which means the
+.I SIZE
+parameter is given in kilo\-, mega\- or gigabytes respectively.
+.B Ntfsresize
+conforms to the SI, ATA, IEEE standards and the disk manufacturers
+by using k=10^3, M=10^6 and G=10^9.
+
+If both
+.B \-\-info(\-mb\-only)
+and
+.B \-\-size
+are omitted then the
+NTFS filesystem will be enlarged to match the underlying
+.I DEVICE
+size.
+.PP
+To resize a filesystem on a partition, you must resize BOTH the filesystem
+and the partition by editing the partition table on the disk. Similarly to
+other command line filesystem resizers,
+.B ntfsresize
+doesn't manipulate the size of the partitions, hence
+to do that you must use a disk partitioning tool as well, for example
+.BR fdisk (8).
+Alternatively you could use one of the many user friendly partitioners that
+uses
+.B ntfsresize
+internally, like Mandriva's DiskDrake, QTParted, SUSE/Novell's YaST Partitioner,
+IBM's EVMS, GParted or Debian/Ubuntu's Partman.
+.PP
+.B IMPORTANT!
+It's a good practice making REGULAR BACKUPS of your valuable data, especially
+before using ANY partitioning tools. To do so for NTFS, you could use
+.BR ntfsclone (8).
+Don't forget to save the partition table as well!
+.SS Shrinkage
+If you wish to shrink an NTFS partition, first use
+.B ntfsresize
+to shrink the size of the filesystem. Then you could use
+.BR fdisk (8)
+to shrink the size of the partition by deleting the
+partition and recreating it with the smaller size.
+Do not make the partition smaller than the new size of
+NTFS otherwise you won't be able to boot. If you did so notwithstanding
+then just recreate the partition to be as large as NTFS.
+.SS Enlargement
+To enlarge an NTFS filesystem, first you must enlarge the size of the
+underlying partition. This can be done using
+.BR fdisk (8)
+by deleting the partition and recreating it with a larger size.
+Make sure it will not overlap with an other existing partition.
+You may enlarge upwards (first sector unchanged) or downwards (last
+sector unchanged), but you may not enlarge at both ends in a single step.
+If you merge two NTFS partitions, only one of them can be expanded to the
+merged partition.
+After you have enlarged the partition, you may use
+.B ntfsresize
+to enlarge the size of the filesystem.
+.SS Partitioning
+When recreating the partition by a disk partitioning tool,
+make sure you create it at the same
+starting sector and with the same partition type as before.
+Otherwise you won't be able to access your filesystem. Use the 'u'
+fdisk command to switch to the reliable sector unit from the
+default cylinder one.
+
+Also make sure you set the bootable flag for the partition if it
+existed before. Failing to do so you might not be able to boot your
+computer from the disk.
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfsresize
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-c\fR, \fB\-\-check\fR
+By using this option ntfsresize will only check the device to ensure that it
+is ready to be resized. If not, it will print any errors detected.
+If the device is fine, nothing will be printed.
+.TP
+\fB\-i\fR, \fB\-\-info\fR
+By using this option without \fB\-\-expand\fP, ntfsresize will determine the
+theoretically smallest shrunken filesystem size supported.
+Most of the time the result is the space
+already used on the filesystem. Ntfsresize will refuse shrinking to a
+smaller size than what you got by this option and depending on several
+factors it might be unable to shrink very close to this theoretical
+size. Although the integrity of your data should be never in risk,
+it's still strongly recommended to make a test run by using the
+\fB\-\-no\-action\fR option before real resizing.
+
+Practically the smallest shrunken size generally is
+at around "used space" + (20\-200 MB). Please also take into account
+that Windows might need about 50\-100 MB free space left to boot safely.
+
+If used in association with option \fB\-\-expand\fP, ntfsresize will determine
+the smallest downwards expansion size and the possible increments to the
+size. These are exact byte counts which must not be rounded.
+This option may be used after the partition has been expanded
+provided the upper bound has not been changed.
+
+This option never causes any changes to the filesystem, the partition is
+opened read\-only.
+.TP
+\fB\-m\fR, \fB\-\-info\-mb\-only\fR
+Like the info option, only print out the shrinkable size in MB. Print nothing
+if the shrink size is the same as the original size (in MB).
+This option cannot be used in association with option \fB\-\-expand\fP.
+.TP
+\fB\-s\fR, \fB\-\-size\fR SIZE\fR[\fBk\fR|\fBM\fR|\fBG\fR]
+Resize filesystem to fit in a partition whose size is
+\fISIZE\fR[\fBk\fR|\fBM\fR|\fBG\fR] bytes by shifting its end and keeping
+its beginning unchanged. The filesystem size is set to be at least one
+sector smaller than the partition.
+The optional modifiers
+.BR k ,
+.BR M ,
+.B G
+mean the
+.I SIZE
+parameter is given in kilo\-, mega\- or gigabytes respectively.
+Conforming to standards, k=10^3, M=10^6 and G=10^9. ki=2^10, Mi=2^20
+and Gi=2^30 are also allowed. Use this option
+with
+.B \-\-no\-action
+first.
+.TP
+\fB\-x\fR, \fB\-\-expand\fR
+Expand the filesystem to the current partition size, shifting down its
+beginning and keeping its end unchanged. The metadata is recreated in the
+expanded space and no user data is relocated. This is incompatible with
+option \-s (or \-\-size) and can only be made if the expanded space is an
+exact multiple of the cluster size. It must also be large enough to hold the
+new metadata.
+
+If the expansion is interrupted for some reason (power outage, etc), you may
+restart the resizing, as the original data and metadata have been kept
+unchanged.
+
+Note : expanding a Windows system partition and filesystem downwards may lead
+to the registry or some files not matching the new system layout, or to
+some important files being located too far from the beginning of the
+partition, thus making Windows not bootable.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+Forces ntfsresize to proceed with the resize operation either without
+prompting for an explicit acceptance, or if the filesystem is marked for
+consistency check. Double the option (-ff, --force --force) to avoid
+prompting even if the file system is marked for check.
+
+Please note, ntfsresize always marks the filesystem
+for consistency check before a real resize operation
+and it leaves that way for extra
+safety. Thus if NTFS was marked by ntfsresize then it's safe to
+use this option. If you need
+to resize several times without booting into Windows between each
+resizing steps then you must use this option.
+.TP
+.B \-n, \-\-no\-action
+Use this option to make a test run before doing the real resize operation.
+Volume will be opened read\-only and
+.B ntfsresize
+displays what it would do if it were to resize the filesystem.
+Continue with the real resizing only if the test run passed.
+.TP
+\fB\-b\fR, \fB\-\-bad\-sectors\fR
+Support disks having hardware errors, bad sectors with those
+.B ntfsresize
+would refuse to work by default.
+
+Prior using this option, it's strongly recommended to make a backup by
+.BR ntfsclone (8)
+using the \-\-rescue option, then running 'chkdsk /f /r volume:' on Windows
+from the command line. If the disk guarantee is still valid then replace it.
+It's defected. Please also note, that no software can repair these type of
+hardware errors. The most what they can do is to work around the permanent
+defects.
+
+This option doesn't have any effect if the disk is flawless.
+.TP
+\fB\-P\fR, \fB\-\-no\-progress\-bar\fR
+Don't show progress bars.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+More output.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Print the version number of
+.B ntfsresize
+and exit.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help and exit.
+.SH EXIT CODES
+The exit code is 0 on success, non\-zero otherwise.
+.SH KNOWN ISSUES
+No reliability problem is known. If you need
+help please try the Ntfsresize FAQ first (see below) and if you
+don't find your answer then send your question, comment or bug report to
+the development team:
+.br
+.nh
+ntfs\-3g\-devel@lists.sf.net
+.hy
+.PP
+There are a few very rarely met restrictions at present: filesystems having
+unknown bad sectors, relocation
+of the first MFT extent and resizing into the middle of a $MFTMirr extent
+aren't supported yet. These cases are detected and
+resizing is restricted to a safe size or the closest safe
+size is displayed.
+.PP
+.B Ntfsresize
+schedules an NTFS consistency check and
+after the first boot into Windows you must see
+.B chkdsk
+running on a blue background. This is intentional and no need to worry about it.
+Windows may force a quick reboot after the consistency check.
+Moreover after repartitioning your disk and depending on the
+hardware configuration, the Windows message
+.B System Settings Change
+may also appear. Just acknowledge it and reboot again.
+.PP
+The disk geometry handling semantic (HDIO_GETGEO ioctl) has changed
+in an incompatible way in Linux 2.6 kernels and this triggered multitudinous
+partition table corruptions resulting in unbootable Windows systems, even if
+NTFS was consistent, if
+.BR parted (8)
+was involved in some way. This problem was often attributed to ntfsresize
+but in fact it's completely independent of NTFS thus ntfsresize. Moreover
+ntfsresize never touches the partition table at all. By changing
+the 'Disk Access Mode' to LBA in the BIOS makes booting work
+again, most of the time. You can find more information about this issue
+in the Troubleshooting section of the below referred Ntfsresize FAQ.

+use this option. If you need
+to resize several times without booting into Windows between each
+resizing steps then you must use this option.
+.TP
+.B \-n, \-\-no\-action
+Use this option to make a test run before doing the real resize operation.
+Volume will be opened read\-only and
+.B ntfsresize
+displays what it would do if it were to resize the filesystem.
+Continue with the real resizing only if the test run passed.
+.TP
+\fB\-b\fR, \fB\-\-bad\-sectors\fR
+Support disks having hardware errors, bad sectors with those
+.B ntfsresize
+would refuse to work by default.
+
+Prior using this option, it's strongly recommended to make a backup by
+.BR ntfsclone (8)
+using the \-\-rescue option, then running 'chkdsk /f /r volume:' on Windows
+from the command line. If the disk guarantee is still valid then replace it.
+It's defected. Please also note, that no software can repair these type of
+hardware errors. The most what they can do is to work around the permanent
+defects.
+
+This option doesn't have any effect if the disk is flawless.
+.TP
+\fB\-P\fR, \fB\-\-no\-progress\-bar\fR
+Don't show progress bars.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+More output.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Print the version number of
+.B ntfsresize
+and exit.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help and exit.
+.SH EXIT CODES
+The exit code is 0 on success, non\-zero otherwise.
+.SH KNOWN ISSUES
+No reliability problem is known. If you need
+help please try the Ntfsresize FAQ first (see below) and if you
+don't find your answer then send your question, comment or bug report to
+the development team:
+.br
+.nh
+ntfs\-3g\-devel@lists.sf.net
+.hy
+.PP
+There are a few very rarely met restrictions at present: filesystems having
+unknown bad sectors, relocation
+of the first MFT extent and resizing into the middle of a $MFTMirr extent
+aren't supported yet. These cases are detected and
+resizing is restricted to a safe size or the closest safe
+size is displayed.
+.PP
+.B Ntfsresize
+schedules an NTFS consistency check and
+after the first boot into Windows you must see
+.B chkdsk
+running on a blue background. This is intentional and no need to worry about it.
+Windows may force a quick reboot after the consistency check.
+Moreover after repartitioning your disk and depending on the
+hardware configuration, the Windows message
+.B System Settings Change
+may also appear. Just acknowledge it and reboot again.
+.PP
+The disk geometry handling semantic (HDIO_GETGEO ioctl) has changed
+in an incompatible way in Linux 2.6 kernels and this triggered multitudinous
+partition table corruptions resulting in unbootable Windows systems, even if
+NTFS was consistent, if
+.BR parted (8)
+was involved in some way. This problem was often attributed to ntfsresize
+but in fact it's completely independent of NTFS thus ntfsresize. Moreover
+ntfsresize never touches the partition table at all. By changing
+the 'Disk Access Mode' to LBA in the BIOS makes booting work
+again, most of the time. You can find more information about this issue
+in the Troubleshooting section of the below referred Ntfsresize FAQ.

+\fBntfstruncate\fR [\fIoptions\fR] \fIdevice\fR \fIfile\fR \fI[attr-type\fR [\fIattr-name\fR]] \fInew-length\fR
+.SH DESCRIPTION
+.B ntfstruncate
+truncates (or extends) a specified attribute belonging to a
+file or directory, to a specified length.
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfstruncate
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+This will override some sensible defaults, such as not using a mounted volume.
+Use this option with caution.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Show a list of options with a brief description of each one.
+.TP
+\fB\-l\fR
+Display licensing information.
+.TP
+\fB\-n\fR, \fB\-\-no-action\fR

+.TP
+\fBattr-type\fR
+Define a particular attribute type to be truncated (advanced use only).
+By default, the unnamed $DATA attribute (the contents of a plain file) will
+be truncated. The attribute has to be specified by a number in decimal
+or hexadecimal :

+[\fIoptions\fR] \fIdevice\fR
+.SH DESCRIPTION
+.B ntfsundelete
+has three modes of operation:
+.IR scan ,
+.I undelete
+and
+.IR copy .
+.SS Scan
+.PP
+The default mode,
+.I scan
+simply reads an NTFS Volume and looks for files that have been deleted. Then it
+will print a list giving the inode number, name and size.
+.SS Undelete
+.PP
+The
+.I undelete
+mode takes the files either matching the regular expression (option \-m)
+or specified by the inode\-expressions and recovers as much of the data
+as possible. It saves the result to another location. Partly for
+safety, but mostly because NTFS write support isn't finished.
+.SS Copy
+.PP
+This is a wizard's option. It will save a portion of the MFT to a file. This
+probably only be useful when debugging
+.I ntfsundelete
+.SS Notes
+.B ntfsundelete
+only ever
+.B reads
+from the NTFS Volume.
+.B ntfsundelete
+will never change the volume.
+.SH CAVEATS
+.SS Miracles
+.B ntfsundelete
+cannot perform the impossible.
+.PP
+When a file is deleted the MFT Record is marked as not in use and the bitmap
+representing the disk usage is updated. If the power isn't turned off
+immediately, the free space, where the file used to live, may become
+overwritten. Worse, the MFT Record may be reused for another file. If this
+happens it is impossible to tell where the file was on disk.
+.PP
+Even if all the clusters of a file are not in use, there is no guarantee that
+they haven't been overwritten by some short\-lived file.
+.SS Locale
+In NTFS all the filenames are stored as Unicode. They will be converted into
+the current locale for display by
+.BR ntfsundelete .
+The utility has successfully displayed some Chinese pictogram filenames and then
+correctly recovered them.
+.SS Extended MFT Records
+In rare circumstances, a single MFT Record will not be large enough to hold the
+metadata describing a file (a file would have to be in hundreds of fragments
+for this to happen). In these cases one MFT record may hold the filename, but
+another will hold the information about the data.
+.B ntfsundelete
+will not try and piece together such records. It will simply show unnamed files
+with data.
+.SS Compressed and Encrypted Files
+.B ntfsundelete
+cannot recover compressed or encrypted files. When scanning for them, it will
+display as being 0% recoverable.
+.SS The Recovered File's Size and Date
+To recover a file
+.B ntfsundelete
+has to read the file's metadata. Unfortunately, this isn't always intact.
+When a file is deleted, the metadata can be left in an inconsistent state. e.g.
+the file size may be zero; the dates of the file may be set to the time it was
+deleted, or random.
+.br
+To be safe
+.B ntfsundelete
+will pick the largest file size it finds and write that to disk. It will also
+try and set the file's date to the last modified date. This date may be the
+correct last modified date, or something unexpected.
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfsundelete
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-b\fR, \fB\-\-byte\fR NUM
+If any clusters of the file cannot be recovered, the missing parts will be
+filled with this byte. The default is zeros.
+.TP
+\fB\-C\fR, \fB\-\-case\fR
+When scanning an NTFS volume, any filename matching (using the
+.B \-\-match
+option) is case\-insensitive. This option makes the matching case\-sensitive.
+.TP
+\fB\-c\fR, \fB\-\-copy\fR RANGE
+This wizard's option will write a block of MFT FILE records to a file. The
+default file is
+.I mft
+which will be created in the current directory. This option can be combined
+with the
+.B \-\-output
+and
+.B \-\-destination
+options.
+.TP
+\fB\-d\fR, \fB\-\-destination\fR DIR
+This option controls where to put the output file of the
+.B \-\-undelete
+and
+.B \-\-copy
+options.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+This will override some sensible defaults, such as not overwriting an existing
+file. Use this option with caution.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Show a list of options with a brief description of each one.
+.TP
+\fB\-i\fR, \fB\-\-inodes\fR RANGE
+Recover the files with these inode numbers.
+.I RANGE
+can be a single inode number, several numbers separated by commas "," or a
+range separated by a dash "\-".
+.TP
+\fB\-m\fR, \fB\-\-match\fR PATTERN
+Filter the output by only looking for matching filenames. The pattern can
+include the wildcards '?', match exactly one character or '*', match zero or
+more characters. By default the matching is case\-insensitive. To make the
+search case sensitive, use the
+.B \-\-case
+option.
+.TP
+\fB\-O\fR, \fB\-\-optimistic\fR
+Recover parts of the file even if they are currently marked as in use.
+.TP
+\fB\-o\fR, \fB\-\-output\fR FILE
+Use this option to set name of output file that
+.B \-\-undelete
+or
+.B \-\-copy
+will create.
+.TP
+\fB\-P\fR, \fB\-\-parent\fR
+Display the parent directory of a deleted file.
+.TP
+\fB\-p\fR, \fB\-\-percentage\fR NUM
+Filter the output of the
+.B \-\-scan
+option, by only matching files with a certain amount of recoverable content.
+.B Please read the caveats section for more details.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Reduce the amount of output to a minimum. Naturally, it doesn't make sense to
+combine this option with
+.BR \-\-scan .
+.TP
+\fB\-s\fR, \fB\-\-scan\fR
+Search through an NTFS volume and print a list of files that could be recovered.
+This is the default action of
+.BR ntfsundelete .
+This list can be filtered by filename, size, percentage recoverable or last
+modification time, using the
+.BR \-\-match ,
+.BR \-\-size ,
+.B \-\-percent
+and
+.B \-\-time
+options, respectively.
+.sp
+The output of scan will be:

+.TP
+\fB\-T\fR, \fB\-\-truncate\fR
+If

+ntfswipe \- overwrite unused space on an NTFS volume
+.SH SYNOPSIS
+\fBntfswipe\fR [\fIoptions\fR] \fIdevice\fR
+.SH DESCRIPTION
+.B ntfswipe
+clears all or part of unused space on an NTFS volume by overwriting
+with zeroes or random bytes.
+.SH OPTIONS
+Below is a summary of all the options that
+.B ntfswipe
+accepts. Nearly all options have two equivalent names. The short name is
+preceded by
+.B \-
+and the long name is preceded by
+.BR \-\- .
+Any single letter options, that don't take an argument, can be combined into a
+single command, e.g.
+.B \-fv
+is equivalent to
+.BR "\-f \-v" .
+Long named options can be abbreviated to any unique prefix of their name.
+.TP
+\fB\-a\fR, \fB\-\-all\fR
+Wipe all unused space. This may take significant time.
+.TP
+\fB\-b\fR, \fB\-\-bytes\fR BYTE-LIST
+Define the allowed replacement bytes which are drawn randomly to overwrite
+the unused space. BYTE-LIST is a comma-separated list of values in
+range 0-255 expressed in octal, decimal or hexadecimal base.
+.TP
+\fB\-c\fR, \fB\-\-count\fR NUM
+Define the number of times the unused space is to be overwritten.
+.TP
+\fB\-d\fR, \fB\-\-directory\fR
+Wipe all the directory indexes, which may contain names of deleted files.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+This will override some sensible defaults, such as not using a mounted volume.
+Use this option with caution.

+\fB\-l\fR, \fB\-\-logfile\fR
+Overwrite the logfile (update journal).
+.TP
+\fB\-m\fR, \fB\-\-mft\fR
+Overwrite the unused space in the MFT (main file table, which contains the
+file names, and the contents of short files).
+.TP
+\fB\-n\fR, \fB\-\-no-action\fR
+Executes the wiping process without writing to device.
+.TP
+\fB\-p\fR, \fB\-\-pagefile\fR
+Overwrite the Windows swap space.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Suppress some debug/warning/error messages.
+.TP
+\fB\-s\fR, \fB\-\-undel\fR
+Overwrite the space which had been allocated to a file which has been deleted
+recently and is still undeletable.
+.TP
+\fB\-t\fR, \fB\-\-tails\fR
+Overwrite the space at the end of files which is unused, but allocated
+because the allocations are always done by full clusters.
+.TP
+\fB\-u\fR, \fB\-\-unused\fR
+Overwrite the space which is currently not allocated to any file (but
+may have been used in the past).
+.TP
+\fB\-U\fR, \fB\-\-unused-fast\fR
+Overwrite the space which is currently not allocated to any file, trying
+not to overwrite the space not written to since the previous wiping.
+.TP

+.SH NAME
+ntfs-3g \- Third Generation Read/Write NTFS Driver
+.SH SYNOPSIS
+.B ntfs-3g
+\fB[-o \fIoption\fP\fB[,...]]\fR
+.I volume mount_point
+.br
+.B mount \-t ntfs-3g
+\fB[-o \fIoption\fP\fB[,...]]\fR

+.br
+.B mount \-t lowntfs-3g
+\fB[-o \fIoption\fP\fB[,...]]\fR
+.I volume mount_point
+.SH DESCRIPTION
+\fBntfs-3g\fR is an NTFS driver, which can create, remove, rename, move
+files, directories, hard links, and streams; it can read and write files,
+including streams, sparse files and transparently compressed files; it can
+handle special files like symbolic links, devices, and FIFOs; moreover it
+provides standard management of file ownership and permissions, including
+POSIX ACLs.
+.PP
+It comes in two variants \fBntfs-3g\fR and \fBlowntfs-3g\fR with
+a few differences mentioned below in relevant options descriptions.
+.PP
+The \fIvolume\fR to be mounted can be either a block device or
+an image file.
+.SS Windows hibernation and fast restarting
+On computers which can be dual-booted into Windows or Linux, Windows has
+to be fully shut down before booting into Linux, otherwise the NTFS file
+systems on internal disks may be left in an inconsistent state and changes
+made by Linux may be ignored by Windows.
+.P
+So, Windows may not be left in hibernation when starting Linux, in order
+to avoid inconsistencies. Moreover, the fast restart feature available on
+recent Windows systems has to be disabled. This can be achieved by issuing
+as an Administrator the Windows command which disables both
+hibernation and fast restarting :
+.RS
+.sp
+powercfg /h off
+.sp
+.RE
+.SS Access Handling and Security
+By default, files and directories are owned by the effective
+user and group of the mounting process, and everybody has
+full read, write, execution and directory browsing permissions.
+You can also assign permissions to a single user by using the
+.B uid
+and/or the
+.B gid
+options together with the
+.B umask,
+or
+.B fmask
+and
+.B dmask
+options.
+.PP
+Doing so, Windows users have full access to the files created by
+.B ntfs-3g.
+.PP
+But, by setting the \fBpermissions\fR option, you can benefit from the full
+ownership and permissions features as defined by POSIX. Moreover, by defining
+a Windows-to-Linux user mapping, the ownerships and permissions are even
+applied to Windows users and conversely.
+.PP
+If
+.B ntfs-3g
+is set setuid-root then non-root users will
+be also able to mount volumes.
+.SS Windows Filename Compatibility
+NTFS supports several filename namespaces: DOS, Win32 and POSIX. While the
+\fBntfs-3g\fR driver handles all of them, it always creates new files in the
+POSIX namespace for maximum portability and interoperability reasons.
+This means that filenames are case sensitive and all characters are
+allowed except '/' and '\\0'. This is perfectly legal on Windows, though
+some application may get confused. The option \fBwindows_names\fP may be
+used to apply Windows restrictions to new file names.
+.SS Alternate Data Streams (ADS)

+.SH OPTIONS
+Below is a summary of the options that \fBntfs-3g\fR accepts.
+.TP
+\fBuid=\fP\fIvalue\fP and \fBgid=\fP\fIvalue\fP
+Set the owner and the group of files and directories. The values are numerical.
+The defaults are the uid and gid of the current process.
+.TP
+.BI umask= value
+Set the bitmask of the file and directory permissions that are not
+present. The value is given in octal. The default value is 0 which
+means full access to everybody.
+.TP
+.BI fmask= value
+Set the bitmask of the file permissions that are not present.
+The value is given in octal. The default value is 0 which
+means full access to everybody.
+.TP
+.BI dmask= value
+Set the bitmask of the directory permissions that are not
+present. The value is given in octal. The default value is 0 which
+means full access to everybody.
+.TP
+.BI usermapping= file-name
+Use file \fIfile-name\fP as the user mapping file instead of the default
+\fB.NTFS-3G/UserMapping\fP. If \fIfile-name\fP defines a full path, the
+file must be located on a partition previously mounted. If it defines a
+relative path, it is interpreted relative to the root of NTFS partition
+being mounted.
+.P
+.RS
+When a user mapping file is defined, the options \fBuid=\fP, \fBgid=\fP,
+\fBumask=\fP, \fBfmask=\fP, \fBdmask=\fP and \fBsilent\fP are ignored.
+.RE
+.TP
+.B permissions
+Set standard permissions on created files and use standard access control.
+This option is set by default when a user mapping file is present.
+.TP
+.B acl
+Enable setting Posix ACLs on created files and use them for access control.
+This option is only available on specific builds. It is set by default
+when a user mapping file is present and the
+.B permissions
+mount option is not set.
+.TP
+.B inherit
+When creating a new file, set its initial protections
+according to inheritance rules defined in parent directory. These rules
+deviate from Posix specifications, but yield a better Windows
+compatibility. The \fBpermissions\fR option or a valid user mapping file
+is required for this option to be effective.
+.TP
+.B ro
+Mount filesystem read\-only. Useful if Windows is hibernated or the
+NTFS journal file is unclean.
+.TP
+.BI locale= value
+This option can be useful when wanting a language specific locale environment.
+It is however discouraged as it leads to files with untranslatable chars
+to not be visible.
+.TP
+.B force
+This option is obsolete. It has been superseded by the \fBrecover\fR and
+\fBnorecover\fR options.
+.TP
+.B recover
+Recover and try to mount a partition which was not unmounted properly by
+Windows. The Windows logfile is cleared, which may cause inconsistencies.
+Currently this is the default option.
+.TP
+.B norecover
+Do not try to mount a partition which was not unmounted properly by Windows.
+.TP
+.B ignore_case \fP(only with lowntfs-3g)
+Ignore character case when accessing a file (\fBFOO\fR, \fBFoo\fR, \fBfoo\fR,
+etc. designate the same file). All files are displayed with lower case in
+directory listings.
+.TP
+.B remove_hiberfile
+Unlike in case of read-only mount, the read-write mount is denied if
+the NTFS volume is hibernated. One needs either to resume Windows and
+shutdown it properly, or use this option which will remove the Windows
+hibernation file. Please note, this means that the saved Windows
+session will be completely lost. Use this option under your own
+responsibility.
+.TP
+.B atime, noatime, relatime
+The
+.B atime
+option updates inode access time for each access.
+
+The
+.B noatime
+option disables inode access time updates which can speed up
+file operations and prevent sleeping (notebook) disks spinning
+up too often thus saving energy and disk lifetime.
+
+The
+.B relatime
+option is very similar to
+.B noatime.
+It updates inode access times relative to modify or change time.
+The access time is only updated if the previous access time was earlier
+than the current modify or change time. Unlike
+.B noatime
+this option doesn't break applications that need to know
+if a file has been read since the last time it was modified.
+This is the default behaviour.
+.TP
+.B delay_mtime[= value]
+Only update the file modification time and the file change time of a file
+when it is closed or when the indicated delay since the previous update has
+elapsed. The argument is a number of seconds, with a default value of 60.
+This is mainly useful for big files which are kept open for a long
+time and written to without changing their size, such as databases or file
+system images mounted as loop.
+.TP
+.B show_sys_files
+Show the metafiles in directory listings. Otherwise the default behaviour is
+to hide the metafiles, which are special files used to store the NTFS
+structure. Please note that even when this option is specified, "$MFT" may
+not be visible due to a glibc bug. Furthermore, irrespectively of
+show_sys_files, all files are accessible by name, for example you can always
+do
+"ls \-l '$UpCase'".
+.TP
+.B hide_hid_files
+Hide the hidden files and directories in directory listings, the hidden files
+and directories being the ones whose NTFS attribute have the hidden flag set.
+The hidden files will not be selected when using wildcards in commands,
+but all files and directories remain accessible by full name, for example you
+can always display the Windows trash bin directory by :
+"ls \-ld '$RECYCLE.BIN'".
+.TP
+.B hide_dot_files
+Set the hidden flag in the NTFS attribute for created files and directories
+whose first character of the name is a dot. Such files and directories
+normally do not appear in directory listings, and when the flag is set
+they do not appear in Windows directory displays either.
+When a file is renamed or linked with a new name, the hidden flag is
+adjusted to the latest name.
+.TP
+.B windows_names
+This option prevents files, directories and extended attributes to be
+created with a name not allowed by windows, because
+.RS
+.RS
+.sp
+- it contains some not allowed character,
+.br
+- or the last character is a space or a dot,
+.br
+- or the name is reserved.
+.sp
+.RE
+The forbidden characters are the nine characters " * / : < > ? \\ | and
+those whose code is less than 0x20, and
+the reserved names are CON, PRN, AUX, NUL, COM1..COM9, LPT1..LPT9,
+with no suffix or followed by a dot.
+.sp
+Existing such files can still be read (and renamed).
+.RE
+.TP
+.B allow_other
+This option overrides the security measure restricting file access
+to the user mounting the filesystem. This option is only
+allowed to root, but this restriction can be overridden by
+the 'user_allow_other' option in the /etc/fuse.conf file.
+.TP
+.BI max_read= value
+With this option the maximum size of read operations can be set.
+The default is infinite. Note that the size of read requests is
+limited anyway to 32 pages (which is 128kbyte on i386).
+.TP
+.B silent
+Do nothing, without returning any error, on chmod and chown operations
+and on permission checking errors,
+when the \fBpermissions\fR option is not set and no user mapping file
+is defined. This option is on by default, and when set off (through option
+\fBno_def_opts\fR) ownership and permissions parameters have to be set.
+.TP
+.B no_def_opts
+By default ntfs-3g acts as if "silent" (ignore permission errors when
+permissions are not enabled),
+"allow_other" (allow any user to access files) and "nonempty"
+(allow mounting on non-empty directories) were set, and "no_def_opts"
+cancels these default options.
+.TP
+.BI streams_interface= value
+This option controls how the user can access Alternate Data Streams (ADS) or
+in other words, named data streams. It can be set to, one of \fBnone\fR,
+\fBwindows\fR or \fBxattr\fR. If the option is set to \fBnone\fR, the user
+will have no access to the named data streams. If it is set to \fBwindows\fR
+(not possible with lowntfs-3g), then the user can access them just like in
+Windows (eg. cat file:stream). If it's set to \fBxattr\fR, then the named
+data streams are mapped to xattrs and user can manipulate them using
+\fB{get,set}fattr\fR utilities. The default is \fBxattr\fR.
+.TP
+.B user_xattr
+Same as \fBstreams_interface=\fP\fIxattr\fP.
+.TP
+.B efs_raw
+This option should only be used in backup or restore situation.
+It changes the apparent size of files and the behavior of read and
+write operation so that encrypted files can be saved and restored
+without being decrypted. The \fBuser.ntfs.efsinfo\fP extended attribute
+has also to be saved and restored for the file to be decrypted.
+.TP
+.B compression
+This option enables creating new transparently compressed files in
+directories marked for compression. A directory is marked for compression by
+setting the bit 11 (value 0x00000800) in its Windows attribute. In such a
+directory, new files are created compressed and new subdirectories are
+themselves marked for compression. The option and the flag have no effect
+on existing files. Currently this is the default option.
+.TP
+.B nocompression
+This option disables creating new transparently compressed files in directories
+marked for compression. Existing compressed files can still be read and
+updated.
+.TP
+.B big_writes
+This option prevents fuse from splitting write buffers into 4K chunks,
+enabling big write buffers to be transferred from the application in a
+single step (up to some system limit, generally 128K bytes).
+.TP
+.B debug
+Makes ntfs-3g to print a lot of debug output from libntfs-3g and FUSE.
+.TP
+.B no_detach
+Makes ntfs-3g to not detach from terminal and print some debug output.
+.SH USER MAPPING
+NTFS uses specific ids to record the ownership of files instead of
+the \fBuid\fP and \fBgid\fP used by Linux. As a consequence a mapping
+between the ids has to be defined for ownerships to be recorded into
+NTFS and recognized.
+.P
+By default, this mapping is fetched from the file \fB.NTFS-3G/UserMapping\fP
+located in the NTFS partition. The option \fBusermapping=\fP may be used
+to define another location. When the option permissions is set and
+no mapping file is found, a default mapping is used.
+.P
+Each line in the user mapping file defines a mapping. It is organized
+in three fields separated by colons. The first field identifies a \fBuid\fP,
+the second field identifies a \fBgid\fP and the third one identifies the
+corresponding NTFS id, known as a \fBSID\fP. The \fBuid\fP and the \fBgid\fP
+are optional and defining both of them for the same \fBSID\fP is not
+recommended.
+.P
+If no interoperation with Windows is needed, you can use the option
+\fBpermissions\fP to define a standard mapping. Alternately, you may define
+your own mapping by setting a single default mapping with no uid and gid. In
+both cases, files created on Linux will appear to Windows as owned by a
+foreign user, and files created on Windows will appear to Linux as owned by
+root. Just copy the example below and replace the 9 and 10-digit numbers by
+any number not greater than 4294967295. The resulting behavior is the same as
+the one with the option permission set with no ownership option and no user
+mapping file available.

+If a strong interoperation with Windows is needed, the mapping has to be
+defined for each user and group known in both system, and the \fBSID\fPs used

+.SH NAME
+ntfs-3g \- Third Generation Read/Write NTFS Driver
+.SH SYNOPSIS
+.B ntfs-3g
+\fB[-o \fIoption\fP\fB[,...]]\fR
+.I volume mount_point
+.br
+.B mount \-t ntfs-3g
+\fB[-o \fIoption\fP\fB[,...]]\fR

+.br
+.B mount \-t lowntfs-3g
+\fB[-o \fIoption\fP\fB[,...]]\fR
+.I volume mount_point
+.SH DESCRIPTION
+\fBntfs-3g\fR is an NTFS driver, which can create, remove, rename, move
+files, directories, hard links, and streams; it can read and write files,
+including streams, sparse files and transparently compressed files; it can
+handle special files like symbolic links, devices, and FIFOs; moreover it
+provides standard management of file ownership and permissions, including
+POSIX ACLs.
+.PP
+It comes in two variants \fBntfs-3g\fR and \fBlowntfs-3g\fR with
+a few differences mentioned below in relevant options descriptions.
+.PP
+The \fIvolume\fR to be mounted can be either a block device or
+an image file.
+.SS Windows hibernation and fast restarting
+On computers which can be dual-booted into Windows or Linux, Windows has
+to be fully shut down before booting into Linux, otherwise the NTFS file
+systems on internal disks may be left in an inconsistent state and changes
+made by Linux may be ignored by Windows.
+.P
+So, Windows may not be left in hibernation when starting Linux, in order
+to avoid inconsistencies. Moreover, the fast restart feature available on
+recent Windows systems has to be disabled. This can be achieved by issuing
+as an Administrator the Windows command which disables both
+hibernation and fast restarting :
+.RS
+.sp
+powercfg /h off
+.sp
+.RE
+.SS Access Handling and Security
+By default, files and directories are owned by the effective
+user and group of the mounting process, and everybody has
+full read, write, execution and directory browsing permissions.
+You can also assign permissions to a single user by using the
+.B uid
+and/or the
+.B gid
+options together with the
+.B umask,
+or
+.B fmask
+and
+.B dmask
+options.
+.PP
+Doing so, Windows users have full access to the files created by
+.B ntfs-3g.
+.PP
+But, by setting the \fBpermissions\fR option, you can benefit from the full
+ownership and permissions features as defined by POSIX. Moreover, by defining
+a Windows-to-Linux user mapping, the ownerships and permissions are even
+applied to Windows users and conversely.
+.PP
+If
+.B ntfs-3g
+is set setuid-root then non-root users will
+be also able to mount volumes.
+.SS Windows Filename Compatibility
+NTFS supports several filename namespaces: DOS, Win32 and POSIX. While the
+\fBntfs-3g\fR driver handles all of them, it always creates new files in the
+POSIX namespace for maximum portability and interoperability reasons.
+This means that filenames are case sensitive and all characters are
+allowed except '/' and '\\0'. This is perfectly legal on Windows, though
+some application may get confused. The option \fBwindows_names\fP may be
+used to apply Windows restrictions to new file names.
+.SS Alternate Data Streams (ADS)
+NTFS stores all data in streams. Every file has exactly one unnamed
+data stream and can have many named data streams. The size of a file is the
+size of its unnamed data stream. By default, \fBntfs-3g\fR will only read
+the unnamed data stream.
+.PP
+By using the options "streams_interface=windows", with the ntfs-3g driver
+(not possible with lowntfs-3g), you will be able to read any named data
+streams, simply by specifying the stream's name after a colon.
+For example:
+.RS
+.sp
+cat some.mp3:artist
+.sp
+.RE
+Named data streams act like normal files, so you can read from them, write to
+them and even delete them (using rm). You can list all the named data streams
+a file has by getting the "ntfs.streams.list" extended attribute.

+limited anyway to 32 pages (which is 128kbyte on i386).
+.TP
+.B silent
+Do nothing, without returning any error, on chmod and chown operations
+and on permission checking errors,
+when the \fBpermissions\fR option is not set and no user mapping file
+is defined. This option is on by default, and when set off (through option
+\fBno_def_opts\fR) ownership and permissions parameters have to be set.
+.TP
+.B no_def_opts
+By default ntfs-3g acts as if "silent" (ignore permission errors when
+permissions are not enabled),
+"allow_other" (allow any user to access files) and "nonempty"
+(allow mounting on non-empty directories) were set, and "no_def_opts"
+cancels these default options.
+.TP
+.BI streams_interface= value
+This option controls how the user can access Alternate Data Streams (ADS) or
+in other words, named data streams. It can be set to, one of \fBnone\fR,
+\fBwindows\fR or \fBxattr\fR. If the option is set to \fBnone\fR, the user
+will have no access to the named data streams. If it is set to \fBwindows\fR
+(not possible with lowntfs-3g), then the user can access them just like in
+Windows (eg. cat file:stream). If it's set to \fBxattr\fR, then the named
+data streams are mapped to xattrs and user can manipulate them using
+\fB{get,set}fattr\fR utilities. The default is \fBxattr\fR.
+.TP
+.B user_xattr
+Same as \fBstreams_interface=\fP\fIxattr\fP.
+.TP
+.B efs_raw
+This option should only be used in backup or restore situation.
+It changes the apparent size of files and the behavior of read and
+write operation so that encrypted files can be saved and restored
+without being decrypted. The \fBuser.ntfs.efsinfo\fP extended attribute
+has also to be saved and restored for the file to be decrypted.
+.TP
+.B compression
+This option enables creating new transparently compressed files in
+directories marked for compression. A directory is marked for compression by
+setting the bit 11 (value 0x00000800) in its Windows attribute. In such a
+directory, new files are created compressed and new subdirectories are
+themselves marked for compression. The option and the flag have no effect
+on existing files. Currently this is the default option.
+.TP
+.B nocompression
+This option disables creating new transparently compressed files in directories
+marked for compression. Existing compressed files can still be read and
+updated.
+.TP
+.B big_writes
+This option prevents fuse from splitting write buffers into 4K chunks,
+enabling big write buffers to be transferred from the application in a
+single step (up to some system limit, generally 128K bytes).
+.TP
+.B debug
+Makes ntfs-3g to print a lot of debug output from libntfs-3g and FUSE.
+.TP
+.B no_detach
+Makes ntfs-3g to not detach from terminal and print some debug output.
+.SH USER MAPPING
+NTFS uses specific ids to record the ownership of files instead of
+the \fBuid\fP and \fBgid\fP used by Linux. As a consequence a mapping
+between the ids has to be defined for ownerships to be recorded into
+NTFS and recognized.
+.P
+By default, this mapping is fetched from the file \fB.NTFS-3G/UserMapping\fP
+located in the NTFS partition. The option \fBusermapping=\fP may be used
+to define another location. When the option permissions is set and
+no mapping file is found, a default mapping is used.
+.P
+Each line in the user mapping file defines a mapping. It is organized
+in three fields separated by colons. The first field identifies a \fBuid\fP,
+the second field identifies a \fBgid\fP and the third one identifies the
+corresponding NTFS id, known as a \fBSID\fP. The \fBuid\fP and the \fBgid\fP
+are optional and defining both of them for the same \fBSID\fP is not
+recommended.
+.P
+If no interoperation with Windows is needed, you can use the option
+\fBpermissions\fP to define a standard mapping. Alternately, you may define
+your own mapping by setting a single default mapping with no uid and gid. In
+both cases, files created on Linux will appear to Windows as owned by a
+foreign user, and files created on Windows will appear to Linux as owned by
+root. Just copy the example below and replace the 9 and 10-digit numbers by
+any number not greater than 4294967295. The resulting behavior is the same as
+the one with the option permission set with no ownership option and no user
+mapping file available.

+.RE
+If a strong interoperation with Windows is needed, the mapping has to be
+defined for each user and group known in both system, and the \fBSID\fPs used
+by Windows has to be collected. This will lead to a user mapping file like :

+.SH AUTHORS
+.B ntfs-3g
+was based on and a major improvement to ntfsmount and libntfs which were
+written by Yura Pakhuchiy and the Linux-NTFS team. The improvements were
+made, the ntfs-3g project was initiated and currently led by long time
+Linux-NTFS team developer Szabolcs Szakacsits (szaka@tuxera.com).
+.SH THANKS
+Several people made heroic efforts, often over five or more
+years which resulted the ntfs-3g driver. Most importantly they are
+Anton Altaparmakov, Jean-Pierre André, Richard Russon, Szabolcs Szakacsits,
+Yura Pakhuchiy, Yuval Fledel, and the author of the groundbreaking FUSE
+filesystem development framework, Miklos Szeredi.

+.SH NAME
+ntfs-3g.secaudit \- NTFS Security Data Auditing
+.SH SYNOPSIS
+.B ntfs-3g.secaudit
+\fB[\fIoptions\fP\fB]\fR
+.I args
+.PP
+Where \fIoptions\fP is a combination of :
+.RS
+-a full auditing of security data (Linux only)
+.RE
+.RS
+-b backup ACLs
+.RE
+.RS
+-e setting extra backed-up parameters (in conjunction with -s)
+.RE
+.RS
+-h displaying hexadecimal security descriptors saved in a file
+.RE
+.RS
+-r recursing in a directory
+.RE
+.RS
+-s setting backed-up ACLs
+.RE
+.RS
+-u getting a user mapping proposal
+.RE
+.RS
+-v verbose (very verbose if set twice)
+.RE
+.PP
+and args define the parameters and the set of files acted upon.
+.PP
+Typing secaudit with no args will display a summary of available options.
+.SH DESCRIPTION
+\fBntfs-3g.secaudit\fR
+displays the ownership and permissions of a set of files on an NTFS
+file system, and checks their consistency. It can be started in terminal
+mode only (no graphical user interface is available.)
+.PP
+When a \fIvolume\fR is required, it has to be unmounted, and the command
+has to be issued as \fBroot\fP. The \fIvolume\fR can be either a block
+device (i.e. a disk partition) or an image file.
+.PP
+When acting on a directory or volume, the command may produce a lot
+of information. It is therefore advisable to redirect the output to
+a file or pipe it to a text editor for examination.
+.SH OPTIONS
+Below are the valid combinations of options and arguments that
+\fBntfs-3g.secaudit\fR accepts. All the indicated arguments are
+mandatory and must be unique (if wildcards are used, they must
+resolve to a single name.)
+.TP
+\fB-h\fP \fIfile\fP
+Displays in an human readable form the hexadecimal security descriptors
+saved in \fIfile\fP. This can be used to turn a verbose output into a very
+verbose output.
+.TP
+\fB-a[rv]\fP \fIvolume\fP
+Audits the volume : all the global security data on \fIvolume\fP are scanned
+and errors are displayed. If option \fB-r\fP is present, all files and
+directories are also scanned and their relations to global security data
+are checked. This can produce a lot of data.
+
+This option is not effective on volumes formatted for old NTFS versions (pre
+NTFS 3.0). Such volumes have no global security data.
+
+When errors are signalled, it is advisable to repair the volume with an
+appropriate tool (such as \fBchkdsk\fP on Windows.)
+.TP
+\fB[-v]\fP \fIvolume\fP \fIfile\fP
+Displays the security parameters of \fIfile\fP : its interpreted Linux mode
+(rwx flags in octal) and Posix ACL[1], its security key if any, and its
+security descriptor if verbose output.
+.TP
+\fB-r[v]\fP \fIvolume\fP \fIdirectory\fP
+displays the security parameters of all files and subdirectories in
+\fIdirectory\fP : their interpreted Linux mode (rwx flags in octal) and Posix
+ACL[1], their security key if any, and their security descriptor if
+verbose output.
+.TP
+.B -b[v] \fIvolume\fP \fI[directory]\fP
+Recursively extracts to standard output the NTFS ACLs of files in \fIvolume\fP
+and \fIdirectory\fP.
+.TP
+\fB-s[ev]\fP \fIvolume\fP \fI[backup-file]\fP
+Sets the NTFS ACLS as indicated in \fIbackup-file\fP or standard input. The
+input data must have been created on Linux. With option \fB-e\fP, also sets
+extra parameters (currently Windows attrib).
+.TP
+\fIvolume\fP \fIperms\fP \fIfile\fP
+Sets the security parameters of file to perms. Perms is the Linux
+requested mode (rwx flags, expressed in octal form as in chmod) or
+a Posix ACL[1] (expressed like in setfacl -m). This sets a new ACL
+which is effective for Linux and Windows.
+.TP
+\fB-r[v]\fP \fIvolume\fP \fIperms\fP \fIdirectory\fP
+Sets the security parameters of all files and subdirectories in
+\fIdirectory\fP to \fIperms\fP. Perms is the Linux requested mode (rwx flags,
+expressed in octal form as in \fBchmod\fP), or a Posix ACL[1] (expressed like
+in \fBsetfacl -m\fP.) This sets new ACLs which are effective for Linux and
+Windows.
+.TP
+\fB[-v]\fP \fImounted-file\fP
+Displays the security parameters of \fImounted-file\fP : its interpreted
+Linux mode (rwx flags in octal) and Posix ACL[1], its security key if any,
+and its security descriptor if verbose output. This is a special case which
+acts on a mounted file (or directory) and does not require being root. The
+Posix ACL interpretation can only be displayed if the full path to
+\fImounted-file\fP from the root of the global file tree is provided.
+.TP
+\fB-u[v]\fP \fImounted-file\fP
+Displays a proposed contents for a user mapping file, based on the
+ownership parameters set by Windows on \fImounted-file\fP, assuming
+this file was created on Windows by the user who should be mapped to the
+current Linux user. The displayed information has to be copied to the
+file \fB.NTFS-3G/UserMapping\fP where \fB.NTFS-3G\fP is a hidden
+subdirectory of the root of the partition for which the mapping is to
+be defined. This will cause the ownership of files created on that
+partition to be the same as the original \fImounted-file\fP.
+.SH NOTE
+[1] provided the POSIX ACL option was selected at compile time. A Posix ACL
+specification looks like "\fB[d:]{ugmo}:[id]:[perms],...\fP" where id is a
+numeric user or group id, and perms an octal digit or a set from the letters
+r, w and x.

+.TH NTFS-3G.USERMAP 8 "February 2010" "ntfs-3g.usermap 1.1.2"
+.SH NAME
+ntfs-3g.usermap \- NTFS Building a User Mapping File
+.SH SYNOPSIS
+.B ntfs-3g.usermap
+\fIwindows-system-device\fP
+\fB[\fIother-ntfs-device\fP...\fB]\fR
+.PP
+Where \fIwindows-system-device\fP is the device containing the Windows system
+whose users are to be mapped to current Linux system.
+.PP
+And \fIother-ntfs-device\fP is another device containing files which are
+to be accessed both by the Windows mentioned above and current Linux system.
+.PP
+the ntfs-3g.usermap command must be started as root, and the designated devices
+must not be mounted.
+.PP
+Typing ntfs-3g.usermap with no args will display a summary of command
+arguments.
+.SH DESCRIPTION
+\fBntfs-3g.usermap\fR
+creates the file defining the mapping of Windows accounts to Linux logins for
+users who owns files which should be visible from both Windows and
+Linux.
+.PP
+It relies on existing files which were created on Windows, trying
+to locate significant files and asking which Linux user or group should
+own them. When a Linux owner or group is requested, the reply may be :
+.PP
+- the uid or gid (numeric or symbolic) of Linux owner or group of the file.
+.RS
+In that situation, no more file with the same Windows owner will be selected.
+.RE
+- or no answer, when not able to define the owner or group.
+.RS
+In that situation another file owned by the same Windows user or group
+may be selected later so that a mapping can be defined.
+.RE
+.PP
+The mappings for standard Windows users, such as "Administrator" or
+"All Users" are defined implicitly. As a consequence a user mapping should
+never be defined as Linux root.
+.PP
+When there are no more significant files, ntfs-3g.usermap create the
+mapping file into the file UserMapping in the current directory. This
+file has to be moved to the hidden directory .NTFS-3G in the root of
+all the NTFS file systems to be shared between Windows and Linux. This
+requires the file system to be mounted, but the created file will not
+be taken into account if not present at mount time, which means the
+file system has to be unmounted and mounted again for the new mapping
+file to be taken into account.
+.SH OPTIONS
+No option is defined for ntfs-3g.usermap.
+.SH EXAMPLES
+Map the users defined on the Windows system present on /dev/sda1 :
+.RS
+.sp
+.B ntfs-3g.usermap /dev/sda1

+.TH NTFS-3G.USERMAP 8 "February 2010" "ntfs-3g.usermap 1.1.2"
+.SH NAME
+ntfs-3g.usermap \- NTFS Building a User Mapping File
+.SH SYNOPSIS
+.B ntfs-3g.usermap
+\fIwindows-system-device\fP
+\fB[\fIother-ntfs-device\fP...\fB]\fR
+.PP
+Where \fIwindows-system-device\fP is the device containing the Windows system
+whose users are to be mapped to current Linux system.
+.PP
+And \fIother-ntfs-device\fP is another device containing files which are
+to be accessed both by the Windows mentioned above and current Linux system.
+.PP
+the ntfs-3g.usermap command must be started as root, and the designated devices
+must not be mounted.
+.PP
+Typing ntfs-3g.usermap with no args will display a summary of command
+arguments.
+.SH DESCRIPTION
+\fBntfs-3g.usermap\fR
+creates the file defining the mapping of Windows accounts to Linux logins for
+users who owns files which should be visible from both Windows and
+Linux.
+.PP
+It relies on existing files which were created on Windows, trying
+to locate significant files and asking which Linux user or group should
+own them. When a Linux owner or group is requested, the reply may be :
+.PP
+- the uid or gid (numeric or symbolic) of Linux owner or group of the file.
+.RS
+In that situation, no more file with the same Windows owner will be selected.
+.RE
+- or no answer, when not able to define the owner or group.
+.RS
+In that situation another file owned by the same Windows user or group
+may be selected later so that a mapping can be defined.
+.RE
+.PP
+The mappings for standard Windows users, such as "Administrator" or
+"All Users" are defined implicitly. As a consequence a user mapping should
+never be defined as Linux root.
+.PP
+When there are no more significant files, ntfs-3g.usermap create the
+mapping file into the file UserMapping in the current directory. This
+file has to be moved to the hidden directory .NTFS-3G in the root of
+all the NTFS file systems to be shared between Windows and Linux. This
+requires the file system to be mounted, but the created file will not
+be taken into account if not present at mount time, which means the
+file system has to be unmounted and mounted again for the new mapping
+file to be taken into account.
+.SH OPTIONS
+No option is defined for ntfs-3g.usermap.
+.SH EXAMPLES
+Map the users defined on the Windows system present on /dev/sda1 :
+.RS
+.sp
+.B ntfs-3g.usermap /dev/sda1
+.sp
+.RE
+.PP
+A detailed example, with screen displays is available on
+http://pagesperso-orange.fr/b.andre/usermap.html
+.SH EXIT CODES
+.B ntfs-3g.usermap
+exits with a value of 0 when no error was detected, and with a value
+of 1 when an error was detected.

+ * Windows to Linux user mapping for ntfs-3g
+ *
+ *
+ * Copyright (c) 2007-2014 Jean-Pierre Andre
+ *
+ * A quick'n dirty program scanning owners of files in
+ * "c:\Documents and Settings" (and "c:\Users")
+ * and asking user to map them to Linux accounts
+ *
+ * History
+ *
+ * Sep 2007
+ * - first version, limited to Win32
+ *
+ * Oct 2007
+ * - ported to Linux (rewritten would be more correct)
+ *
+ * Nov 2007 Version 1.0.0
+ * - added more defaults
+ *
+ * Nov 2007 Version 1.0.1
+ * - avoided examining files whose name begin with a '$'
+ *
+ * Jan 2008 Version 1.0.2
+ * - moved user mapping file to directory .NTFS-3G (hidden for Linux)
+ * - fixed an error case in Windows version
+ *
+ * Nov 2008 Version 1.1.0
+ * - fixed recursions for account in Linux version
+ * - searched owner in c:\Users (standard location for Vista)
+ *
+ * May 2009 Version 1.1.1
+ * - reordered mapping records to limit usage of same SID for user and group
