Suggested replacement, mapshaper, is a Node package instead of a Python package…?

It looks like it's intended for people writing programs using Node, but I'm using Python (as is, presumably, just about everybody who used Kartograph.py). So how do I install and use it? I tried doing some Google searches but found nothing helpful.

Also, kartograph.org has kartograph.py right there on the front page and says nothing about it being deprecated.
