10%D This style is mostly for myself \unknown\ to get an idea of what I need to
11%D talk about, in this case the rather drastic transformation of the \CONTEXT\
12%D code base to \MKIV\ and \LUA.

20\startitem Most users now use \MKIV, with an occasional fall-back on \MKII. \stopitem \FlushStep
21\startitem The code base is now completely split, with the exception of some modules. \stopitem \FlushStep
22\startitem Some solutions are implemented in \LUA\ with only a small wrapper at the \TEX\ end. \stopitem \FlushStep

47\startitem The complete \CONTEXT\ user interface is available at the \LUA\ end (context namespace). \stopitem \FlushStep
48\startitem Eventually all \LUA\ solutions will have a dual interface: \LUA\ (all kind of namespaces) and
49towards \TEX\ (the command namespace). \stopitem \FlushStep
50\startitem Some of the support \LUA\ modules can also be used independent from \CONTEXT. \stopitem \FlushStep
