// atl.cpp : Implementation of DLL Exports.
// You will need the NT SUR Beta 2 SDK or VC 4.2 or higher in order to build
// this project. This is because you will need MIDL 3.00.15 or higher and new
// headers and libs. If you have VC 4.2 installed, then everything should
// already be configured correctly.
// Note: Proxy/Stub Information
// To build a separate proxy/stub DLL,
// run nmake -f atlps.mak in the project directory.
