# Submit bkbits.net repository changes to the CIA bot, who in turn
# forwards the messages to #commits on IRC and a project IRC channel,
# as configured below. If your project isn't on bkbits.net, you may need to
# make several changes in the script itself. See "bk help triggers" for the
# basic documentation to how this works. There's a trick: bkbits.net don't
# have triggers enabled, so we run locally on the pushing machine.
#
# It makes sure that only pushes to public repositories at bkbits.net
# get broadcasted.

# 1) Edit the configuration script `ciabot.config'.
# 2) Put this script in a file named post-outgoing.ciabot in
#    BitKeeper/triggers/pre-apply.ciabot in your project.
# 3) Check in, commit and push the configuration and this script
#    to your repository on bkbits.net.
# 4) The next time anyone pulls the project, they'll get the script.
#    From then on, BitKeeper does the rest, whenever someone pushes
#    back to bkbits.net.
# 4) ?
# 5) Profit! :^)
