 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.

	"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.
