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-descriptors
         Run generate_descriptor_proto.sh to regenerate all the checked in
         proto sources.
   -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-debug
         Skip the Xcode Debug configuration.
   --skip-xcode-release
         Skip the Xcode Release configuration.
   --skip-xcode-osx
         Skip the invoke of Xcode to test the runtime on OS X.
   --skip-objc-conformance
         Skip the Objective C conformance tests (run on OS X).
   --xcode-quiet
         Pass -quiet to xcodebuild.
