+# PROBLEMS WITH SKIA DEBUGGING?? READ THIS...
+#
+# The debug build results in changes to the Skia headers. This means that those
+# using libskia must also be built with the debug version of the Skia headers.
+# There are a few scenarios where this comes into play:
+#
+# (1) You're building debug code that depends on libskia.
+#   (a) If libskia is built in release, then define SK_RELEASE when building
+#       your sources.
+#   (b) If libskia is built with debugging (see step 2), then no changes are
+#       needed since your sources and libskia have been built with SK_DEBUG.
+# (2) You're building libskia in debug mode.
+#   (a) RECOMMENDED: You can build the entire system in debug mode. Do this by
+#       updating your buildspec.mk to include TARGET_BUILD_TYPE=debug
+#   (b) You can update all the users of libskia to define SK_DEBUG when they are
+#       building their sources.
+#
+# NOTE: If neither SK_DEBUG or SK_RELEASE are defined then Skia checks NDEBUG to
+#       determine which build type to use.
