      Parses command line options and parameter list.  args is the
      argument list to be parsed, without the leading reference to the
      running program.  Typically, this means "sys.argv[1:]".  shortopts
      is the string of option letters that the script wants to
      recognize, with options that require an argument followed by a
      colon (i.e., the same format that Unix getopt() uses).  If
      specified, longopts is a list of strings with the names of the
      long options which should be supported.  The leading '--'
      characters should not be included in the option name.  Options
      which require an argument should be followed by an equal sign
      ('=').
  
      The return value consists of two elements: the first is a list of
      (option, value) pairs; the second is the list of program arguments
      left after the option list was stripped (this is a trailing slice
      of the first argument).  Each option-and-value pair returned has
      the option as its first element, prefixed with a hyphen (e.g.,
      '-x'), and the option argument as its second element, or an empty
      string if the option has no argument.  The options occur in the
      list in the same order in which they were found, thus allowing
      multiple occurrences.  Long and short options may be mixed.
