A lovely irc bot. Uses POE underneath and can happily pull all sorts of data --- it can list CPAN testers smoke reports, any of the info from the module list, provide a URL for the CPANwiki _and_ it can even get reviews and ratings from this site. Great module.
This module is very easy to use and extend. What's better, you usually only have to worry about configuration. If the distribution were to come with an example program for running a CPAN Robot -- that took command line arguments or a simple configuration file -- it would receive a "5" for Ease of Use.
