Plum is an automation host for the network chat protocol IRC. Written in Java, Plum takes advantage of Java's dynamic class loading to insert functionality into the client on-the-fly. Coupled with the selection of available modules, Plum is a quick way to provide channel services for your channel. Plum grew out of a desire to combine several existing simple channel service bots in a way that was easily extensible by all channel participants (assuming they can develop in Java, which most could) Key Features of Plum:

   * On-the-fly pluggable/unpluggable modules.
   * in-IRC authentication and control
   * Several modules available:
         o Help system

         o Link "Vernie"ing (retrieves and parses URLs for relevant information, such as title and content length)
