/**
 * \file
 *
 * This file contains functions to integrate with the windows services API.
 * This means it handles the commandline switches to install and remove
 * the service (via CreateService and DeleteService), it handles
 * the ServiceMain() main service entry point when started as a service,
 * and it handles the Handler[_ex]() to process requests to the service
 * (such as start and stop and status).
