+// *******************************************************************************
+// *
+// * Module Name:
+// *   NPClientWraps.cpp
+// *
+// * Software Engineer:
+// *   Doyle Nickless - GoFlight Inc., for Eye Control Technology.
+// *
+// * Abstract:
+// *   This module implements the wrapper code for interfacing to the NaturalPoint
+// *   Game Client API.  Developers of client apps can include this module into
+// *   their projects to simplify communication with the NaturalPoint software.
+// *
+// *   This is necessary since the NPClient DLL is run-time linked rather than
+// *   load-time linked, avoiding the need to link a static library into the
+// *   client program (only this module is needed, and can be supplied in source
+// *   form.)
+// *
+// * Environment:
+// *   User mode
+// *
