- * The Gateway is the central object of a CRISTAL process. It initializes,
- * maintains and shuts down every other subsystem in both the client and the
- * server.
- *
- * Child objects:
- * <ul>
- * <li>LDAPLookup - Provides access to the CRISTAL directory. Find or
- * search for Items or Agents.
- * <li>EntityProxyManager - Gives a local proxy object for Entities found
- * in LDAP. Execute activities in Items, query or subscribe to Entity data.
- * <li>TransactionManager - Access to the configured CRISTAL databases
- * <li>CorbaServer - Manages the memory pool of active Entities
- * <li>mORB - the Orbacus CORBA ORB
- * </ul>
