# PROVIDE: haproxy
# REQUIRE: DAEMON LOGIN
# KEYWORD: shutdown
#
# Add the following lines to /etc/rc.conf to enable haproxy:
#
# haproxy_enable (bool): default: "NO"
# Set to "YES" to enable haproxy
# haproxy_pidfile (str): default: /var/run/haproxy.pid
# Set to the full path of the pid file
# haproxy_config (str): default: %%PREFIX%%/etc/haproxy.conf
# Set to the full path of the config file
# haproxy_flags (str): default: Autogenerated using pidfile and config options
# Set to override with your own options
# haproxy_profiles (str): default: empty
# Set to space-separated list of profiles: for each profile separate haproxy
# process will be spawned, with haproxy-${profile}.conf config file.
# You can override default pidfile and config file for each profile with
# haproxy_${profile}_config and haproxy_${profile}_pidfile.
