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

+\startitem We have passed the point of no return already years ago. \stopitem \FlushStep
+\startitem Most users now use \MKIV, with an occasional fall-back on \MKII. \stopitem \FlushStep
+\startitem The code base is now completely split, with the exception of some modules. \stopitem \FlushStep
+\startitem Some solutions are implemented in \LUA\ with only a small wrapper at the \TEX\ end. \stopitem \FlushStep

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