Erwin is an IRC-bot in Perl, using POE, written with modularity and expandability in mind. Installing and configuring modules is very easy, compared to lots of other Perl bots where you have to read the source and add your own code in the various event loops. Adding additional functionality is as easy as writing a subroutine that returns something and configuring a regex to use that subroutine. By typing "!google keyword", for instance, "Google::Search" gets "keyword" as an argument, searches Google with that keyword and returns a couple of URLs. Further expandability can be achieved using "plug-ins". Plug-ins subclass "Erwin::Plugin", and can recieve and take control over various events. For example does the pastebin-plugin need the ability to take control over every line sent privately by some user, and e.g. a quiz module would need to get every single message sent to a channel while a quiz is going on.
