+//
+// Under windows, when multiple versions of maya are installed, 
+// maya2egg can accidentally use the wrong version of OpenMaya.dll.
+// This small wrapper program alters your PATH and MAYA_LOCATION
+// environment variables in order to ensure that maya2egg finds the
+// right DLLs.
+//
+// To use this wrapper, maya2egg.exe must be renamed to 
+// maya2egg-wrapped.exe.  Then, this wrapper program must be
+// installed as maya2egg.exe
