# *									* #
# *  This is a web server start, stop and restart script.		* #
# *									* #
# *  Recommended installation:						* #
# *									* #
# *  1)	Rename this script to 'htrestart'.				* #
# *									* #
# *  2) Set permissions to 700 or whatever is appropriate for you.	* #
# *									* #
# *  3)	Create the following two symbolic links to this script:		* #
# *									* #
# *	ln -s htrestart htstart						* #
# *	ln -s htrestart htstop						* #
# *									* #
# *  Now, to stop the server, just run 'htstop'. To start it, run	* #
# *  run 'htstart'. Or if you make a config change and you need to	* #
# *  restart it (nicely), run 'htrestart'.				* #
# *									* #
