+// Interfaces to the cIsThread class representing an OS-independent wrapper for a class that implements a thread.
+// This class will eventually suupersede the old cThread class
+
+/*
+Usage:
+To have a new thread, declare a class descending from cIsClass.
+Then override its Execute() method to provide your thread processing.
+In the descending class' constructor call the Start() method to start the thread once you're finished with initialization.
