Printing Complete Usage of xcodebuild

I found how to print ”complete usage” of xcodebuild.

There’s nothing in the Apple’s document related to that.

What is xcodebuild?

xcodebuild builds one or more targets contained in an Xcode project, or builds a scheme contained in an Xcode workspace or Xcode project.

On Terminal.app, run the following:

$ xcodebuild -help
