UPDATE I've added code to handle .pod files as well as .pm files. This means you can put Pod::perl or Pod::perlreftut in the query box to see the HTML equivalents of "perldoc perl" etc. You can also see a directory listing of the Pod:: hierarchy (or any hierarchy) by putting a slash after th the hierarchy name (e.g. mod=Pod/ will display a clickable list of pods in the Pod::* hierarchy).
