6    The \LUAMETATEX\ engine is a follow up on \LUATEX. It integrates the \TEX\
7    text rendering engine, the \METAPOST\ graphic engine and the \LUA\ script
8    interpreter. The development is part of the \CONTEXT\ macro package
9    development. This macro package tightly integrates the three subsystems. The
10    \LUAMETATEX\ code is part of the \CONTEXT\ distribution.

14    The \LUAMETATEX\ engine is lean and mean. There is for instance no backend
15    code present. In \CONTEXT\ this is handled in \LUA. Graphic inclusion is also
16    delegated to \LUA. The \TEX\ frontend is a slightly extended version of the
17    \LUATEX\ one. System depedencies are minimized. Where possible we stay close
18    to the original \TEX\ concept because that is a well documented reference.
19    The binary can also be used as stand alone \LUA\ engine.

23    The \METAPOST\ library also has access to \LUA, which means that the language
24    can be enhanced and functionality added on demand. There are several graphic
25    libraries provided in \CONTEXT. This graphical language is efficient in
26    runtime and graphical output. In combination with \LUA\ we have a high
27    performance graphical subsystem that can handle a huge amount of data.
28    Additional text (like labels) is typeset at high quality.

32    The \LUA\ code that comes with \CONTEXT\ contains a lot of helper code which
33    means that one can set up selfcontained workflows without many extra
34    dependencies. Documents can be encoded in \TEX, \LUA, \XML\ or whatever
35    suits. There is support for databases too.

39    The \CONTEXT\ code base evolved over time. The basic functionality is quite stable.
40    The move from \MKII\ to \MKIV\ to \LMTX\ has been gradual. The efficiency in terms
41    of code and performance has been improved stepwise. Development continues and beta
42    releases occur on a regular basis. The \CONTEXT\ user community is quite willing
43    to experiment with betas that can be installed alongside stable snapshots.

47    The installation is relatively small (fonts make up much of it) and updating is
48    easy. We operate in the \TEX\ Directory Structure, which is a proven concept.
