/*

File:   schedule.H

Purpose:

        Defines routines that can be used to build programs perform
        scheduling.

Associated Files:

        The routines are implemented in the schedule.C file. The
        routines used classes & methods defined in the various included
        files (new.h, lego.h, ...).
