usage: ${NAME} [OPTIONS]

This script does the common build steps needed.

OPTIONS:

 General:

   -h, --help
         Show this message
   -c, --clean
         Issue a clean before the normal build.
   -a, --autogen
         Start by rerunning autogen & configure.
   -r, --regenerate-cpp-descriptors
         The descriptor.proto is checked in generated, cause it to regenerate.
   -j #, --jobs #
         Force the number of parallel jobs (useful for debugging build issues).
   --core-only
         Skip some of the core protobuf build/checks to shorten the build time.
   --skip-xcode
         Skip the invoke of Xcode to test the runtime on both iOS and OS X.
   --skip-xcode-ios
         Skip the invoke of Xcode to test the runtime on iOS.
   --skip-xcode-osx
         Skip the invoke of Xcode to test the runtime on OS X.
