PROGRAM_DESCRIPTION=\
"This script is used to generate an NDK release package from scratch.

This process is EXTREMELY LONG and consists in the following steps:

  - downloading toolchain sources from the Internet
  - patching them appropriately (if needed)
  - rebuilding the toolchain binaries for the host system
  - rebuilding the platforms and samples directories from ../development/ndk
  - packaging everything into a host-specific archive

This can take several hours on a dual-core machine, even assuming a very
nice Internet connection and plenty of RAM and disk space.

Note that on Linux, if you have the 'mingw32' package installed, the script
will also automatically generate a windows release package. You can prevent
that by using the --platforms option.

IMPORTANT:
        If you intend to package NDK releases often, please read the
        file named docs/DEVELOPMENT.TXT which provides ways to do that
        more quickly, by preparing toolchain binary tarballs that can be
        reused for each package operation. This will save you hours of
        your time compared to using this script!
