Jitsu is a meta build system for Ninja

A while back I hit upon Ninja, a very fast and very simple build system that is apparently used for building Chromium. Can’t remember where I first heard of it, might’ve been Hacker News or just somebody’s tweet, but having been interested in build systems for years, at least since setting up Linux builds from scratch for a big piece of software while working on my M.Sc. thesis, I immediately started playing around with it.
