PROGRAM_DESCRIPTION=\
"Package a new set of release packages for the Android NDK.

You will need to have generated one or more prebuilt binary tarballs
with the build/tools/rebuild-all-prebuilts.sh script. These files should
be named like <toolname>-<system>.tar.bz2, where <toolname> is an arbitrary
tool name, and <system> is one of: $SYSTEMS

Use the --prebuilt-dir=<path> option to build release packages from the
binary tarballs stored in <path>.

Alternatively, you can use --prebuilt-ndk=<file> where <file> is the path
to a previous NDK release package. It will be used to extract the toolchain
binaries and copy them to your new release. Only use this for experimental
package releases.

The generated release packages will be stored in a temporary directory that
will be printed at the end of the generation process.
