#
# Even at the best of times, your bot will get k-lined by one operator or
# another on a server you're running your bot on. This script will 'hopefully'
# handle this by removing it from your bot's server list when it detects
# you've been k-lined there. Thus, stopping IRC server admins getting
# rather peeved at the constant connects from your host.
#
# USAGE:
#      The actual handling of removing the server from your server list
#      and writing it to the 'klines' file is handled automatically when
#      your bot receives the k-line signal, but there are some DCC commands
#      that have been added, these are:
#
#      .klines - Lists the 'klines' file showing servers that your bot
#                has registered as being k-lined on.
#     .unkline <server> - Removes the k-line from the server *joke* ;)
#                         Actually, this removes the server from the list
#                         of servers to remove.
