Comments:
    *  [arg] means arg is optional, need use --opt=arg to specify an argument
       <arg> means arg is required, and -f a -f b will get the latest 'b'
       {arg} means arg is required, and -f a -f b will get a list 'a b'

    *  if arg is required, '--opt arg' is same as '--opt=arg'

    *  '-opt' will be treated as:
           '--opt'    if 'opt' is defined;
           '-o -p -t' if 'opt' is undefined;
           '-o -p=t'  if 'opt' is undefined and '-p' need an argument;
