PROGRAM_DESCRIPTION=\
"Rebuild the prebuilt GAbi++ binaries for the Android NDK.

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

This requires a temporary NDK installation containing platforms and
toolchain binaries for all target architectures.

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>/$GABIXX_SUBDIR, but you can override this with the --out-dir=<path>
option.
