Source control does all that. Subversion is free and easy to setup and use.

Mesh may be a solution, but isn't source control.

>The reason I do not use a source control program is that the customer is a small-time manufacturer who doesn't want to mess with source control. He wants a simple setup program that will install easily and lay everything out in its appropriate place.
