# This is the installation portion of kippo.
# This is somewhat jumbled together. There is no "easy_install" for kippo,
# and there isn't a way to regenerate the twistd plugin cache.
#
# Use the services.kippo options to properly configure if on NixOS.
# On other platforms there is a problem with hardcoded paths.
# Your best bet is to change kippo source to customise
# or manually copy the proper filesystems.
# At a minimum the following are required in  /var/lib/kippo:
#     honeyfs/
#     fs.pickle
#     data/
#     txtcmds/
#
# There is also benefit in preparing /var/log/kippo
#     tty/
#     dl/
#
# Most of these files need read/write permissions.
#
# Read only files: kippo.tac and kippo.cfg
#
# Execution may look like this:
# twistd -y kippo.tac --syslog --pidfile=kippo.pid
#
# Use this package at your own risk.
