  Command Line Options
  -------------------------------------------------------

  Valid command line options.

  The function get_option() uses this table to check if an
  option is valid and if it takes a value (also called an
  option argument).  To add an option to zip just add it
  to this table and add a case in the main switch to handle
  it.  If either shortopt or longopt not used set to "".

   The fields:
       shortopt     - short option name (1 or 2 chars)
       longopt      - long option name
       value_type   - see zip.h for constants
       negatable    - option is negatable with trailing -
       ID           - unsigned long int returned for option
       name         - short description of option which is
                        returned on some errors and when options
                        are listed with -so option, can be NULL
*/
