* This program is merely to demonstrate my PHP coding skills/style
* It actually does function, it is designed to run on cPanel/WHM web
* servers.  It will get a list of all the users on the system and
* as long as their plan is not "no_backup" it will create a back up
* of their www directory (only) to a temporary location and ftp it to
* a remote server.  It will then e-mail the user.
*
* I am aware a much better version of this feature is built into cPanel
* this is merely a sample program.
