# zncnotice: weechat script to convert ZNC status PRIVMSGs to NOTICEs
# © 2016 Hugo Landau <hlandau@devever.net>  MIT License
# Tested with Weechat 1.5. Older versions may or may not work.
#
# Settings:
#   plugins.var.python.zncnotice.prefix=*
#     The nickname prefix used by ZNC for its psuedo-users. Usually * but can be
#     changed to something else. Must match the ZNC configuration. (default: "*")
#
# Instructions for use:
#   1. Load script.
#   2. If using a prefix other than *, set plugins.var.python.zncnotice.prefix.
#   3. PRIVMSGs from nicknames with that prefix will now be converted to NOTICEs.
