Is this repo maintained?

[deankarn]

@drewjocham of course it is, you can clearly see that by looking at the recent activity. Please note the tone of what I write next is meant to be informative and not negative.

A while back I asked for help from the community to maintain this repo and only a hand full of people stepped up to help(thank you all whom did) but not enough to satisfy everyone.

This isn’t the only repository or even language I maintain open source work for and so people will just have to be patient with how and when I can find time to work on this codebase.
