LuaTeX uses Lua scripting both as an extension to the TeX macro language and as an extension to the typesetting engine itself. A (growing) number of TeX internals are made available to the embedded lua interpreter. . LuaTeX uses code and interfaces from Aleph to improve the typesetting of non-latin alphabet languages, instead of the TeXXeT code present in the current releases of pdfTeX. . Unicode and OpenType font support are added progressively, and regular pdfTeX development will continue in this branch as well. . The multi-lingual extensions are coded and merged by Taco Hoekwater. Swift progress in that area is made possible by a joint grant from Colorado State University and TUG, under the 'Oriental TeX' project. . This package only contains the barebone binary. If you are searching for support file, formats etc install texlive-luatex.
