# Converter for ZNC logs 1.4 to 1.6                                            #

# This is a quick script to edit all your ZNC logs to the new ZNC log path and #
# naming style in 1.6. Make sure to take a backup oh your logs when running.   #
# *** ZNC should not be running when you run this script ***                   #
#                                                                              #

# Caveats:                                                                     #
# This currently only works if the logs module was enabled by the user. If you #
# have it enabled as a global mod or network mod, this script *will not work*  #
# without some changes. Also, if you are using a custom logging format in ZNC, #
# this will not work.                                                          #

# TO RUN:                                                                      #
# - Download and run in the log directory.                                     #
