weechat/scripts/python/awl.py

"""
  This script shows buffer list in infobar. Nothing more.
  It's inspired by `awl.pl` irssi script, but is less advanced. :)

  The script is in the public domain.

0.1 - initial commit
0.2 - added `show_servers` option
0.3 - infobar is actually redrawed only if that's necessary
