      [Experimental] This command is experimental. API and output compatibility is not guaranteed.

      Usage:
        rbs diff --format markdown --type-name Foo --before before_sig --after after_sig

      Print diff for rbs environment dir

      Examples:

        # Diff dir1 and dir2 for Foo
        $ rbs diff --format markdown --type-name Foo --before dir1 --after dir2

        # Confirmation of methods related to Time class added by including stdlib/time
        $ rbs diff --format diff --type-name Time --after stdlib/time
