Ricer is an Icecap 'bot written in Ruby. (Ruby icecap robot, or Ricer for short)
It's being developed by daxxar, and is still not in any usable form. As soon as it is, a feature-list will be posted here.
(This project will most likely replace i2bpp, irssi2 bot++ (named so before irssi2 was renamed to icecap), the C++ bot I was working on before)
Contact me on irc (#icecap on Freenode, nick 'daxxar') if you have any questions.
