PROGRAM_PARAMETERS="<toolchain-src-dir>"
PROGRAM_DESCRIPTION=\
"This script is used to rebuild all host and target prebuilts from scratch.
You will need to give the path of a toolchain source directory, one which
is typically created with the download-toolchain-sources.sh script.

Unless you use the --ndk-dir option, all binaries will be installed to the
current NDK directory.

All prebuilts will then be archived into tarball that will be stored into a
specific 'package directory'. Unless you use the --package-dir option, this
will be: $PACKAGE_DIR

Please read docs/DEV-SCRIPTS-USAGE.TXT for more usage information about this
script.
