* @brief CIAO's Execution Manager implementation
*
* $Id$
*
* ExecutionManager is the DnC entity which is the starting point for
* the deployment process. This entity collaborates with other entities
* including Logging Facility, TargetManager, and
* DomainApplicationManager entities to facilitate the deployment and
* launching of components. In our current design, the ExecutionManager
* is started as an executable on a give host and registered with the
* name service. The Executor/client obtains this reference and starts
* the deployment process.
