            [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
