That's a really grandiose title for my sole published work on CPAN, but there it is.
The work in question: UPS::Nut which is a module that allows you to talk to Network UPS Tools' upsd in a Perlish fashion.
Update - 2005-12-22: It has come to my attention (Thanks, Craig!) that UPS::Nut doesn't work with the new version of NUT. I'll fix it when I have some time, but it may be a while, as I'm pretty busy. I would certainly welcome any assistance anyone cared to offer, whether it's contributing code, or contributing documentation on the new upsd interface. I'm "popefelix" on Gmail.
