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.
   --full-build
         By default only protoc & the conformance test runner are built within protobuf,
         this option will enable a full build/test of the entire protobuf project.
   --skip-conformance-runner
         Skip building the conformance runner (when not doing a --full-build)
   --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-xcode-macos
         Skip the invoke of Xcode to test the runtime on OS X.
   --skip-xcode-tvos
         Skip the invoke of Xcode to test the runtime on tvOS.
   --skip-objc-conformance
         Skip the Objective C conformance tests (run on OS X).
   --skip-xcpretty
         By default, if xcpretty is installed, it will be used, this option will
         skip it even it it is installed.
   --xcode-quiet
         Pass -quiet to xcodebuild.
