// This recognizer is part of the supporting test code for T_NonNativeAppsStep.CPP
// This recognizer only exists to associate the document names defined in T_NonNativeAppsStep.h 
// with the TstNonNativeApp.exe application.
// This enables T_NonNativeAppsSt ep.CPP to launch TstNonNativeApp.app by starting the document names.
//
