IRC bots

I’ve setup a simple IRC bot on one of our channels on quakenet. The bot accepts certain commands and also stores facts (factoids). I saw a very nice implementation of this kind of bot over on lspace where a lot of the ILUG guys hangout. Our bot is nowhere near as advanced and probably never will be, but it’s rather amusing to watch the reaction of people who’ve never seen one in action.
I still haven’t managed to get it to do certain things, which is a little frustrating. At the moment it will accept the following:
!coffee
And respond
“bkjeeves gives X a cup of steaming espresso”
What I can’t work out is how to get it to respond to
!coffee X
where X is the nick of the user.
After spending a lot of time searching on Google I can only find references to the infobot bot on which blootbot is based. Unfortunately the blootbot documentation is sadly lacking.
I suppose I could ask the maintainer of the other bot to give me some help, but as he’s an employee of one of our competitors I doubt if he’d be too helpful.
