I guess then the user should have called `command script import awesome_backtrace_analyzer` to import the package rather than the `main.py` inside it. But I get your point. FWIW just adding the `$ROOT` is how I did the original implementation before adding the tests for the nested directories and `.py` files that Dave suggested. It would solve this issues but then doesn't support those scenarios. I don't know if it would be less confusing that you can't pass a relative path to a `.py` file or that you can't import another module as you described. > I think setting the import path to $ROOT would actually make the sys.path > manipulation serve some useful purpose (and also reduce the number of > sys.path entries we add).

I would prefer this approach if it didn't require to name the module ourself. Any heuristic will have the risk of being ambitious as well (which is probably why the API makes you specify the module name).
