blines patch for ircu
=====================

This is some random b:lines patch for ircu2.10.11.07 I believe. I
garbled it up somewhere on the net and put it up here in case anyone
needs it.
I am NEITHER author NOR do I provide support for this in any way.
If you are the author, please contact me for removal or so I can add the
info.

I do not know how well this patch works or whether it is stable or
secure to use.
The b:lines allow you to set alias commands to ease the use of services
for your users, i.e. they can type /authserv instead of /msg authserv in
clients that forward unknown commands to the server.

Have fun.
