• SR-1503 Can't test module under linux that has main.swift in it

Issue Description:

Currently SwiftPM forces all code to be put into a separate module in order to be testable. This is extra work and really isn't necessary for CLI tools.

At the very least, the result error is non-obvious.

{{

For instance, the attached project, I would need to move Utilities.swift out into a module to test it.
