From the doc: 'allows you to combine both a DOS program and a Windows program into one EXE. When you run a Windows program from DOS, it gives a message like 'This program requires Windows' - right ? With this program, it is possible to replace that message with a real program that you provide. If you had both a DOS version and a Windows version of something, you could place both the main EXE's in one file. Either that or you could add a more creative message than 'This program requires Windows' - something that tells the user *how* to type 'WIN' at the DOS prompt, etc. Cool, right ? '
