# This plugin calls the pynma bindings via python when somebody says your
# nickname, sends you a query, etc.
#
# Requires:
# Weechat 0.3.0
# pynma.py (NMA python bindings) - This is the python API for NMA.  Take it
#   from https://raw.github.com/sitaktif/weechat_plugins_nma/master/pynma.py
#   and put it in the same direactory as nma.py.
#   Note: the pynma.py script is taken from https://github.com/uskr/pynma and
#     is not modified. The only reason you should use the one in the weechat
#     plugin repo (as opposed to the pynma repo) is that you are guaranteed
#     that pynma.py is at a version that is compatible with the weechat plugin.

#     message.
# 2012-05-06, sitaktif

#     default delimiters with brackets and make lines 80 chars wide.
