# fcgiwrap startup script
#
# PROVIDE: fcgiwrap
# REQUIRE: LOGIN
# KEYWORD: shutdown
#
# Add the following to /etc/rc.conf[.local] to enable this service
#
# fcgiwrap_enable="YES"
#
# You can fine tune others variables too:
# fcgiwrap_socket="unix:/var/run/fcgiwrap.sock" 
# this could also be:
# - tcp:[ipv4_addr]:port (for ipv4)
# - tcp6:[ipv6_addr]:port (for ipv6)
# fcgiwrap_flags=
# Use fcgiwrap_user to run fcgiwrap as user
# Use fcgiwrap_group to run fcgiwrap as group
# Use fcgiwrap_socket_mode to change the mode of the socket
# Use fcgiwrap_socket_owner to change the owner of the socket
# Use fcgiwrap_socket_group to change the group of the socket

# fcgiwrap rc.d script supports multiple profiles (a-la rc.d/nginx)
# When profiles are specified, the non-profile specific parameters become defaults.
# You need to make sure that no two profiles have the same socket parameter.
#
# Example:
#
# fcgiwrap_enable="YES"
# fcgiwrap_profiles="myserver myotherserver"
# fcgiwrap_flags="-c 4"
# fcgiwrap_socket_owner="www"
# fcgiwrap_myserver_socket="unix:/var/run/fcgiwrap.myserver.socket"
# fcgiwrap_myserver_user="myuser"
# fcgiwrap_myserver_group="mygroup"
# fcgiwrap_myotherserver_socket="unix:/var/run/fcgiwrap.myotherserver.socket"
# fcgiwrap_myotherserver_user="myotheruser"
# fcgiwrap_myotherserver_group="myothergroup"
# fcgiwrap_myserver_socket_mode="0775"
# fcgiwrap_myotherserver_flags=""  # No flags for this profile.
