About
=====
Guifications, are notifications windows styled after those found in msn,
deadaim, and newer version of aim, yahoo instant messenger, and a lot of
other applications. I've fashioned them after being as user customizable
as possible. It is entirely gtk based and there for should compile on
anything that Pidgin will compile on.
