// = TITLE
// This client logging daemon is a mediator that receives logging
// records from local applications processes and forwards them to
// the server logging daemon running on another host.
//
// = DESCRIPTION
// The default implementation uses an <ACE_SPIPE_Stream> to
// receive the logging message from the application and an
// <ACE_SOCK_Stream> to forward the logging message to the
// server. However, on platforms that don't support
// <ACE_SPIPEs> (e.g., Win32) we use sockets instead.
