cx_freeze is almost irrelevant here; all the following considerations are
about your application structure, it doesnt matter if you use cx_freeze
later (or any other tool).

No, usually the main function is outside the package. The package is a
library, and main() *uses* that library, as a client.

I would say, "In the main script, obviously :)" But since you're asking it
may not be so obvious...
It appears that your main script is exec.py - so there should be it.
I suppose you run your application this way:
exec.py -some -options file.ext
(perhaps a bare exec.py is enough) so using the idiom above, inside exec.py
you can detect when someone is running it as a script.

exec.py is not a good name, since this is the "public" entry point to your
application, and should be more meaningful.
Usually it is not inside the package, just uses it.
I suggest you look into other Python applications, to see how they are
