/**
* @class ACE_Service_Manager
*
* @brief Provide a standard ACE service for managing all the services
* configured in an ACE_Service_Repository.
*
* This implementation is simple and just handles each client
* request one at a time. There are currently 3 types of requests:
* - List services: If the string "help" is sent, return a list of all
* the services supported by the Service Configurator.
* - Reconfigure: If the string "reconfigure" is sent trigger a
* reconfiguration, which will re-read the local <svc.conf> file.
* - Process directive: If neither "help" nor "reconfigure" is sent,
* simply treat the incoming string as a process directive and pass
* it along to <ACE_Service_Config::process_directive>. This allows
* remote configuration via command-line instructions like
* % echo suspend My_Remote_Service | telnet hostname 3911
*
* Each request is associated with a new connection, which is closed
* when the request is processed. In addition, you must be using the
* singleton <ACE_Reactor::instance> in order to trigger
* reconfigurations.
