// MODULE: TSMapAbstract.cpp
//
// PURPOSE: Part of launching a Local Troubleshooter from an arbitrary NT5 application
// Data types and abstract classes for mapping from the application's way of naming
// a problem to the Troubleshooter's way.
// Implements the few concrete methods of abstract base class TSMapRuntimeAbstract.
