| PROGRAM_DESCRIPTION=\ |
| "Rebuild the prebuilt GNU libsupc++ / libstdc++ binaries for the Android NDK. |
| |
| This script is called when packaging a new NDK release. It will simply |
| rebuild the GNU libsupc++ and libstdc++ static and shared libraries from |
| sources. |
| |
| This requires a temporary NDK installation containing platforms and |
| toolchain binaries for all target architectures, as well as the path to |
| the corresponding gcc source tree. |
| |
| By default, this will try with the current NDK directory, unless |
| you use the --ndk-dir=<path> option. |
| |
| The output will be placed in appropriate sub-directories of |
| <ndk>/$GNUSTL_SUBDIR, but you can override this with the --out-dir=<path> |
| option. |
