Dependency Walker -- A remedy for distribution headaches

If you have ever tried to give away a reasonably complicated program that was written and compiled on windows to another user you should be very familiar with complaints of missing DLLs, and other dependencies and module mismatches etc., etc. These erros can manifest themselves in many forms (The procedure entry point could not be located in the dynamic link library; The application or DLL is not a valid Windows image or even Program too big to fit in memory.) This is particularly so if you happen to be developing with a complex build environment that is tightly integrated with windows system, like visual studio (I often use Visual C++ 2005/2008 express (a.k.a. free) editions and they create a lot of trouble in deployment!)
