    # SOME INFOS : fairly standard (debian) init script.
    # Note that node doesn't create a PID file (hence --make-pidfile)
    # has to be run in the background (hence --background)
    # and NOT as root (hence --chuid)

    # #
    #
    # 1) Don't forget to also modify the COMMENTED fields in the "### BEGIN INIT INFO"
    # below (don't uncomment them) if you wish to install system-wide with update-rc.d
    # eg: provides, Short-Description, Description
    #
    # 2) in case you have different node.js servers running, each init.d script should
    # (obviously) have a UNIQUE BASE name so that PIDS do not conflict
    # --> name them accordingly
    # eg: node_static_server, node_express1, node_load_balancer.sh...
    #
    # 3) copy the renamed/modified script(s) to /etc/init.d
    # chmod 755,
    #
    # 4) if you wish the Daemon to be lauched at boot / stopped at shutdown :
    # INSTALL : update-rc.d scriptname defaults
    # (UNINSTALL : update-rc.d -f scriptname remove)
    #
    # 5) based on : Debian /etc/init.d/skeleton
    # modified by : Peter Host (www.oghme.com)

    # Short-Description: DEBIAN initscript for node.js servers/apps
    # Description: ex : proxy server is a node.js http server listening on
    # port 8080 (relayed from 80 by iptables). It balances
    # http requests between the main nodejs server
    # (nodejs.mydomain.com:8000), the static file-server
    # (static.mydomain.com) and the legacy apache server
    # (apache.mydomain.com) and possibly other servers
    # place this file in /etc/init.d.
