# PROVIDE: nginx
# REQUIRE: LOGIN cleanvar
# KEYWORD: shutdown

#
# Add the following lines to /etc/rc.conf to enable nginx:
# nginx_enable (bool):    Set to "NO" by default.
#       Set it to "YES" to enable nginx
# nginx_profiles (str):   Set to "" by default.
#       Define your profiles here.
# nginx_pid_prefix (str): Set to "" by default.
#       When using profiles manually assign value to "nginx_"
#       for prevent collision with other PIDs names.
# nginxlimits_enable (bool):  Set to "NO" by default.
#       Set it to yes to run `limits $limits_args`
#       just before nginx starts.
# nginx_flags (str):    Set to "" by default.
#       Extra flags passed to start command.
# nginxlimits_args (str): Default to "-e -U www"
#       Arguments of pre-start limits run.
