/**
* @file Server_Main.h
*
* $Id$
*
* Declares a generic object that acts as "main" for a CORBA server.
* @author Dale Wilson <wilson_d@ociweb.com>
*
* This object supports creation of a relatively simple CORBA server.
* The object implements "main" for a process.
* A single servant is created and initialized as the process begins
* execution. The lifetime of this initial servant is the lifetime of
* the process.
* The servant is free to create other servants as necessary.
* The servant can capture command line options.
* A callback method in the ORB event loop allows the servant to act
* asynchronously if necessary.
* The callback method allows the servant to request process termination
* and specify the status to be returned from the process.
*
* The application should create a C/C++ main that looks something like:
* #include <tao/Utils/Server_Main.h>
* #include "Xyzzy_i.h"
* int ACE_TMAIN (int argc, ACE_TCHAR *argv[])
* {
* Server_Main<Xyzzy_i> servant ("Xyzzy");
* return servant.run(argc, argv);
* }
*
* The servant implementation (Xyzzy_i in this case) must implement
* the following methods:
* Xyzzy_i (); // null constructor
* ~Xyzzy_i (); // destructor
* int parse_args (int argc, char * argv[]);
* int init (CORBA::ORB_ptr orb );
* int idle(int &result);
* int fini (void);
* const char * identity () const;
*
* parse_args, self_register, self_unregister return 0 if ok, nonzero for error.
* idle returns 0 to continue execution; nonzero to exit -- returning "result" from the process
* identity provides a string to identify this servant in log messages.
*
