Description: Pastebot is a pastebin server and IRC bot in one program.  Users submit short pieces of text to the web server, and the IRC bot announces them in IRC.  Pastebot may have invented the pastebin. As of the time of this writing, Wikipedia’s Pastebin article cites Pastebot as the earliest recorded pastebin.
