# PROVIDE: buildbot-worker
# REQUIRE: LOGIN
# KEYWORD: shutdown
#
# Add the following lines to /etc/rc.conf to run 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_uid (user):		User to run buildbot-worker as.
#					Default: "buildbot"
#
# buildbot_worker_gid (group):		Group to run buildbot-worker as.
#					Default: "buildbot"
#
# buildbot_worker_basedir (path):    	Location for buildbot-worker base directory
#                               	Default: %%PREFIX%%/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="/usr/home/foo/buildbot"
# buildbot_worker_foo_uid="foo"
# buildbot_worker_foo_gid="foo"
#
# buildbot_worker_bar_enable="YES"
# buildbot_worker_bar_basedir="/usr/home/buildbot/"
