LGTM! Thanks a bunch for the PR. Any idea if this works under Windows? If not I can check.

Seems like it doesn't work under Win.

Thanks for checking. I'll then rewrite it to node script. Will get to this within a couple of hours.

Moved from Shell script to Nodejs script. Works on Windows as well.

Awesome - tested that out locally too and it works well. Only thing I'd like to see (and I don't mind doing it myself post-merge) is instead of using ./scripts, put the script in the existing config/ dir.

Moved to config/
