How create a Init Script LSB Header for this script in Debian?

I have below script, but how can I create an LSB Header for it in Debian? I want to put in my init.d. I know that for Fedora is ok, but for Debian I don’t know. Or where and how I put in rc.local?

  #!/bin/sh

Answer

You need to have the following block at the head of your file:

### BEGIN INIT INFO
# Provides:          scriptname
# Required-Start:    $remote_fs $syslog
# Required-Stop:     $remote_fs $syslog
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Start daemon at boot time
# Description:       Enable service provided by daemon.
### END INIT INFO

Be sure to customize that to your needs.
