# History
# 2014-5-3, John Anderson <sontek@gmail.com>
#   version 0.5.3: Fixed short_own bug introduced in 0.5, notify the short url
#                instead of appending to the message (returning to behavior
#                from 0.4)
# 2013-12-25, John Anderson <sontek@gmail.com>
#   version 0.5: Added support for latest weechat (0.4+)
# 2011-10-24, Dmitry Geurkov <dmitry_627@mail.ru>
#   version 0.4.1: added: option "ignore_list" for a blacklist of shorten urls.
# 2011-01-17, nils_2 <weechatter@arcor.de>
#   version 0.4: URI will be shorten in /query, too.
#              : added: option "short_own".
# 2010-11-08, John Anderson <sontek@gmail.com>:
#   version 0.3: Get python 2.x binary for hook_process (fixes problem
#                when python 3.x is default python version, requires
#                WeeChat >= 0.3.4)
