 PROGRAM_DESCRIPTION=\
 "Rebuild libportable.a for the Android NDK.

 This script builds libportable.a for app link with portable header.

 This requires a platform.git/development and 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>/$LIBPORTABLE_SUBDIR, but you can override this with the --out-dir=<path>
 option.
