This newsgroup is not for writing Perl programs for people (though you
may luck out and someone will do it anyway, because they're
sufficiently bored). It's about discussing Perl programs. So please
read the documentation first, and try and write some code; we're much
more inclined to help someone who's made a little effort than someone
who says, "I need you to write my code for me, for free, fast!".
