Yes, that is actually what I have now, except that there are no command line arguments. If there were any command line args, then I would keep what I have (a very short driver program). All of this code that spews out explanations to the user about the config file is already part of the object. This is not a module test target, it is more analogous to a regex decompile thing.

At the end of the day, I may or may not do this. But if I want to do it, I know how to do it. This is actually not a "big deal" either way. I have already released the 6th year code and as such this is more of an academic question. However major revisions are planned for year #7. I've got months to think about this. I just wanna understand the options that I have.
