Usage:  pod2html --help --infile=<name> --outfile=<name>
   --verbose --index --noindex

Options:
  --help         - prints this message.
  --[no]index    - generate an index at the top of the resulting html
                   (default behavior).
  --infile       - filename for the pod to convert (input taken from stdin
                   by default).
  --outfile      - filename for the resulting html file (output sent to
                   stdout by default).
  --title        - title that will appear in resulting html file.
  --[no]verbose  - self-explanatory (off by default).

Note that pod2html is DEPRECATED, and this version implements only
 some of the options known to older versions.
For more information, see 'perldoc pod2html'.
