/*
 Types:

  P_BOOLEAN  : Looks for a + or - immidiately after the option.
               If none found (space or other option), -1 is passed.

  P_NUMVALUE : Grabs the value after the option (whitespace ignored).
               If no value is given, -1 is passed.

  P_STRING   : Grabs the string after the option (leading whitespace
               is ignored).  If no string was present, NULL is returned.

 Notes:

   A filename or string is normally terminated by a space (always a single
   word long).  If a filename or string is enclosed in quotations ("blah
   blah"), then the string is not terminated until the closing quote is
   encountered.
