 # PROVIDE: buildbot-worker
 # REQUIRE: LOGIN
 # KEYWORD: shutdown
 
 #
 # Add the following lines to /etc/rc.conf to enable buildbot-worker:
 #
 # buildbot_worker_enable (bool):	Set to "YES" to enable buildbot-worker.
 #               					Default: "NO"
 # buildbot_worker_flags (flags):	Set extra command flags here. See buildbot-worker(8)
 #               					Default: Empty ("").
 # buildbot_worker_user (user):		User to run buildbot-worker as.
 #               					Default: "buildbot"
 # buildbot_worker_basedir (path):   Location for buildbot-worker base directory
 #                               	Default: /usr/local/etc/buildbot-worker
 # buildbot_worker_profiles (str):   Define profiles names. Space-delimited.
 #                               	Default: Empty ("")
 #
 # This rc.d script supports multiple "profiles". When profiles are
 # specified, the non-profile specific parameters become defaults.
 #
 # Example:
 #
 # buildbot_worker_profiles="foo bar"
 #
 # buildbot_worker_foo_enable="YES"
 # buildbot_worker_foo_basedir="/var/db/buildbot/workers/foo"
 # buildbot_worker_foo_user="foo"
 #
 # buildbot_worker_bar_enable="YES"
 # buildbot_worker_bar_basedir="/var/db/buildbot/workers/bar"
