# PROVIDE: buildslave
# REQUIRE: LOGIN
# KEYWORD: shutdown
#
# Add the following lines to /etc/rc.conf to run buildslave:
#
# buildslave_enable (bool):	Set to "YES" to enable buildslave.
#				Default: "NO"
#
# buildslave_flags (flags):	Set extra command flags here. See buildslave(8)
#				Default: Empty ("").
#
# buildslave_uid (user):	User to run buildslave as.
#				Default: "buildbot"
#
# buildslave_gid (group):	Group to run buildslave as.
#				Default: "buildbot"
#
# buildslave_basedir (path):    Location for buildslave base directory
#                               Default: %%PREFIX%%/etc/buildslave
#
# buildslave_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:
#
# buildslave_profiles="foo bar"
#
# buildslave_foo_enable="YES"
# buildslave_foo_basedir="/usr/home/foo/buildbot"
# buildslave_foo_uid="foo"
# buildslave_foo_gid="foo"
#
# buildslave_bar_enable="YES"
# buildslave_bar_basedir="/usr/home/buildbot/"
