#!/bin/bash
# info: update system queue
# options: pipe
#
# This function is responsible queue processing. Restarts of services,
# scheduled backups, web log parsing and other heavy resource consuming
# operations are handled by this script. It helps to optimize system behaviour.
# In a nutshell Apache will be restarted only once even if 10 domains are
# added or deleted.
