Revision: 1f1cf67ddcd63e44a2b76b612c8dad1f9e28c6eb
Ancestor: fd65d4df88206e4dee702505a543e2ca35dfd5e8
Author: sadrul at pidgin.im
Date: 2008-01-22T07:38:01
Branch: im.pidgin.pidgin

Modified files:
        finch/gntblist.c finch/gntblist.h

ChangeLog: 

Add a buddy list manager for finch. This allows plugins to show the buddylist
in 'Online/Offline' grouping, account-specific grouping, no-grouping, or even
multi-level grouping.
The same can be done for Pidgin. I think it'd be cool if someone does that.
