This code is in early stages of development and contains more bugs than features. _Do not_ expect it to be compatible with normal documents. Also later versions will contain many breaking changes.
You need an up-to-date TeX Live installation and the latest version of LuaMetaTeX. Additionally a current development version of luaotfload is required. (Of course, luaotfload is not necessary if you only want to use `luametaplain` without Unicode fonts.)
IF you are not using Linux x64 or Windows x64, you additionally need to compile a special library version of LuaTeX's kpathsea Lua binding. The source is available under https://github.com/zauguin/luametalatex-kpse . After compiling, the resulting `kpse.so` or `kpse.dll` has to be stored in the main directory of luametalatex (the same directory where `luametalatex-init.lua` is stored)
Obtain `luametatex` from ConTeXt, drop the binary into the same location where your `luatex` binary is installed and copy (or sym-link) the file `luametalatex.lua` into the same directory. Additionally create a sym-link `luametalatex` to `luametatex` in the same directory. Then install `luametalatex` into your texmf tree by running `l3build install` in this repository.
to your local `fmtutil.cnf` and configure paths for luametalatex in your `texmf.cnf`. Then you should be able to run `mktexlsr` followed by `fmtutil-sys --byfmt luametalatex` to generate the format.
