so that debugging/checking can be done easily, I will provide a working sample of what 
 gets $::fd line ;#-- read a line from socket
would have in it when I want this bot to trigger its actions.

[davou] I've edited the function roll_formater down so that it's much shorter... I've gotten the bot to connect to IRC, and join the channel mentioned in $::chan, but it leaves just as fast as it gets in... does anyone know why it's doing this? - [RS]: Easiest way to find out is to add ''puts $line'' right after the ''gets $::fp line'' and see what comes in.
