                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
