Is this a if-you-want-it-make-a-pr situation or a this-project-is-done situation?

Want feedback from author

@saiichihashimoto @evilebottnawi Sorry guys, had a 2nd kid born this year and haven't been using this tool for a while since CSS-in-JS took over (well not quite).

A PR is more than welcome, I promise to review promptly.

All the magic is in 1 file: cli.js Please also see the README and Contributing Guidelines

I can also add a collaborator if anyone is interested.
Someone already forked (copied) this package and I was planning to check out their additions:
https://github.com/Donov4n/stylelint-find-new-rules/issues/2

Are you up for a small PR?

[alexander-akait]

@alexilyaev I can take care of the project, but also have very limited time

[alexilyaev]

@evilebottnawi Added you as a collaborator, you should receive an email. This is a low maintenance project, not too much to do here. Opening a new issue to discuss further action.

[alexander-akait]

thanks!
