B<Parse the command line options passed to the program.>

    arg 1) The number of arguments passed to ap_getopt to parse
    arg 2) The array of command line options to parse
    arg 3) A string of characters that are acceptable options to the program.
           characters followed by ":" are required to have an option 
           associated 
    arg 4) The next option found.  There are four potential values for 
           this variable on exit. They are:
               APR_EOF    --  No more options to parse
               APR_BADCH  --  Found a bad option character
               APR_BADARG --  Missing parameter for the found option
               Other      --  The next option found.
    arg 5) The pool to operate on.

B<NOTE>:  Arguments 2 and 3 are most commonly argc and argv from 
          main(argc, argv)
