Overview:

 The scheduling service can run in one of two different modes of
 operation, an off-line configuration mode, and a run-time execution mode.
 The application uses the Scheduler_Factory to specify in which mode 
 it would like to use the scheduling service.
 
 In the configuration mode, the application registers RT_Infos containing
 operation characteristics with the off-line scheduler, and also specifies
 operation dependencies. The Event Channel also registers RT_Infos for its
 own operations, and specifies any additional dependencies introduced by
 subscription or event correllation. 
 
 Once all operations are registered, the  application invokes the
 scheduler's compute_scheduling method.  The scheduler generates a
 "schedule" consisting of operation priorities and sub-priorities, and
 determines whether or not the schedule is feasible.  The scheduler also 
 produces queue specification information that can be used to configure
 the dispatching module's number and kinds of queues (this
 automatic dispatching module configuration will appear in a TAO release
 *very* soon). The application then may ask the config scheduler to dump
 it's schedule to a header file.
 
 The Sched_Conf.cpp file in this directory is an example of how this is done.
 Building and running the Sched_Conf executable will produce a header file
 called Sched_Conf_Runtime.h, which is included by Sched_Conf_Runtime.cpp.
 
 The dumped header file contains tables with the static scheduling and 
 configuration information. The Sched_Conf_Runtime application passes this 
 information to the run-time scheduler at start-up.  The application may also 
 re-register its operations to verify the correct operations were loaded. The 
 Sched_Conf_Runtime does this, and in fact exercises a number of methods
 of the run-time scheduler to ensure it gives correct responses for the
 table of operations with which it was instantiated.

Program operation:

 build Sched_Conf
 run Sched_Conf
 build Sched_Conf_Runtime
 run Sched_Conf_Runtime
