### BEGIN INIT INFO
# Provides: stunnel4
# Required-Start: $local_fs $remote_fs
# Required-Stop: $local_fs $remote_fs
# Should-Start: $syslog
# Should-Stop: $syslog
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Start or stop stunnel 4.x (SSL tunnel for network daemons)
# Description: Starts or stops all configured SSL network tunnels. Each *.conf file in
# /etc/stunnel/ will spawn a separate stunnel process. The list of files
# can be overriden in /etc/default/stunnel, and that same file can be used
# to completely disable *all* tunnels.
