# include common function and variable definitions

PROGRAM_DESCRIPTION=\
"Rebuild one of the following NDK C++ runtimes: $CXX_STL_LIST.
This script is called when pacakging a new NDK release. It will simply
rebuild the static and shared libraries of a given C++ runtime from
sources.
Use the --stl=<name> option to specify which runtime you want to rebuild.
This requires a temporary NDK installation containing platforms and
toolchain binaries for all target architectures.
By default, this will try with the current NDK directory, unless
you use the --ndk-dir=<path> option.
If you want to use clang to rebuild the binaries, please use
--llvm-version=<ver> option.
The output will be placed in appropriate sub-directories of
<ndk>/sources/cxx-stl/$CXX_STL_SUBDIR, but you can override this with
the --out-dir=<path> option.
