This is Lua 5.5.1, released on 24 Jul 2026. For installation instructions, license details, and further information about Lua, see doc/readme.html.
The Lua interpreter from the official source code tarballs at https://lua.org/download.html which are contained in the master branch and modifications for Mhatxotic/Engine are in a separate branch with a suffix of -mxe. This layout is more manageable than using a fork of the official Lua repository. Lua has a MIT license and is © Lua.Org, PUC-Rio.
