> its being maintained by a tiny number of maintainers That is true, but it is quite stable and it works well. The last released version is from 2015. The last LaTeX release was 2e in 1994. LaTeX 3 is apparently still being developed by a small number of maintainers.

The source code is released irregularly and placed at the http://www.pragma-ade.com http://www.pragma-ade.com website." There's a git mirror of the releases.[1] > Also it is difficult to install It's in TeXLive and works fine. There was a time of intensive development a few years ago, and TeXLive decided to include older, more stable versions. > and hard to find documentation for. The main documentation is the reference manual, linked to from the home page [2]. That said, it's a real shame there isn't more web-friendly documentation. The Wiki has some commands documented, but others are either missing or out of date.
