code: protected static void addCowthinkOption() {
  		if (!options.hasOption(null)) {
  			options.addOption(null, Opt.THINK.text, false, "");
  		}
  	}
docs: Calling this method results in adding the non-standard "--cowthink" option to the accepted commandline flags.
  This is useful if calling cowsay as an executable JAR where there is no other way to determine a
  `cowsay` or a `cowthink` invocation.
