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.
