We have a basic system that we sell to many clients, but we also sometimes customize certain programs for particular clients. I need a way to build and distribute custom EXE's for each client. So far, I plan to have a separate directory for each client that contains any/all of their custom programs. The common programs will be kept in one place. What would be the best way to build EXE's so that it pulls custom programs from the client's directory but all other programs from the general directory?

I also need to be able to run the programs from my office as if I was a client, i.e. with all of their customization. So I guess I would save the generated EXE's in their directory and run those, or run the basic EXE if a custom one doesn't exist.

Has anyone done anything like this? Any ideas, thoughts, etc.? Thanks!
