 PROGRAM_DESCRIPTION=\
 "Rebuild the prebuilt GNU libsupc++ / libstdc++ binaries for the Android NDK.

 This script is called when packaging a new NDK release. It will simply
 rebuild the GNU libsupc++ and libstdc++ static and shared libraries from
 sources.

 This requires a temporary NDK installation containing platforms and
 toolchain binaries for all target architectures, as well as the path to
 the corresponding gcc source tree.

 By default, this will try with the current NDK directory, unless
 you use the --ndk-dir=<path> option.

 The output will be placed in appropriate sub-directories of
 <ndk>/$GNUSTL_SUBDIR, but you can override this with the --out-dir=<path>
 option.
