# PROVIDE: spdu
# REQUIRE: LOGIN
# KEYWORD: shutdown
#
# Add the following to /etc/rc.conf[.local] to enable this service
#
# spdu_enable="YES"
# spdu_name="servername"
#
# spdu rc.d script supports multiple targets (a-la rc.d/nginx)
# When targets are specified, the non-target specific parameters become defaults,
# except for spdu_target_name which will default to "target"
#
# This is inspired by and largely copied from
# https://svnweb.freebsd.org/ports/head/www/fcgiwrap/files/fcgiwrap.in?revision=307542&view=co
# 
# Example:
#
# spdu_enable="YES"
# spdu_targets="myserver myotherserver"
