I can make the user provide the program file and start from there but then the references in other units not related to the  main program will not be found.

Mattias says we can call AddStartUnit multiple times but there's no logic I can use besides adding all files in the provided directories.

Here's what I'm trying to implement:

It's just a project wide search so what can we do besides just add all files found in the project?
