  getopt --options v:: --longoptions verbose:: -- --verbose arg
   
• Accept a -r and --verbose flag, a --accept option with an optional argument and add a --target with a required argument option with shorthands:
   
  getopt --options rv::s::t: --longoptions verbose,source::,target: -- -v --target target
