# Humbug trac plugin -- sends humbugs when tickets change.
|
|
#
|
|
# Install by placing in the plugins/ subdirectory and then adding
|
|
# "humbug_trac" to the [components] section of the conf/trac.ini file,
|
|
# like so:
|
|
#
|
|
# [components]
|
|
# humbug_trac = enabled
|
|
#
|
|
# You may then need to restart trac (or restart Apache) for the bot
|
|
# (or changes to the bot) to actually be loaded by trac.
|
|
#
|
|
# Our install is trac.humbughq.com:/home/humbug/trac/
