Feedback: package polices code?

I discovered `pipreqs` via [this SO answer](https://stackoverflow.com/a/31684470/3333992), and it seemed like just what I needed... except for the fact that it polices my code? I have a big set of non-production-level code for which I wanted a `requirements.txt`. While running `pipreqs` on my target folder, I kept getting errors like `IndentationError: unexpected indent` or `IndentationError: unexpected indent`. I can't polish the code now, I just need someone else to be able to replicate my environment and run the code by checking only for the modules I use, otherwise I would just go for `pip freeze`.

I don't see an option to run `pipreqs` in non-linting mode, is there one? In any case, it would also be useful to have this behavior documented somewhere.

Start with pipreqs' command-line handling and the code that parses Python files in the target folder; the issue does not name specific files or tests. Check whether a non-linting mode exists and how parsing errors are handled. Done means malformed or non-production code can be processed as requested, with the behavior documented if an option is available.
