 * This script wipes out your Chamilo installation completely: databases,
 * courses directories, configuration files and all other temp directories.
 * It only works when launched from the command line and requires Chamilo to
 * be installed (otherwise it will not find the references as to the paths and
 * databases to delete). It only wipes out stuff and directories it knows are 
 * created by Chamilo though, so don't worry about your own files if you didn't
 * store them in variable Chamilo directories.
 * Requires Chamilo LMS 1.9 or greater
