feature_request(path): Custom packages path support

[Kristinita]

1. Summary

It would be nice, if yolk3k will support check licenses from custom path.

Similar issue for pip-licenses package.

2. Argumentation

Example: I use Pelican — static site generator and plugins for it, written by Python. Pelican plugins must installed to custom folder — usually pelican-plugins, not to default site-packages. I don't know, how possible check licenses from pelican-plugins folder.

3. Example of expected behavior

If:

yolk -l -f license --path output/pelican-plugins

yolk3k will check licenses from output/pelican-plugins folder recursively.

4. Not helped

I don't find already existing packages, that solve this problem. For example, I try:

• license_lister,
• license_info,
• plicense,
• pip-licenses,
• pylicense.

Thanks.
