54    \starttitle[title={Using \CONTEXT}]
55
56    The \CONTEXT\ macro package is more than just a \TEX\ processor,
57    various input is possible, some we show here. An example of a
58    method not shown here is fetching data from a database. The
59    various input methods can be combined, so depending on what you
60    need you can mix \TEX\ (for typesetting text), \METAPOST\ (for
61    producing graphics) or \LUA\ (as language for manipulating
62    data.
63
64    All these methods are quite efficient and always have access to
65    the full power of the typesetting engine.
66
67    When you use \CONTEXT\ with \LUAMETATEX, you get a reasonable
68    small self contained component that can be used in workflows
69    that need quality rendering. The ecosystem is rather future
70    proof too.
71
72    The \CONTEXT\ macro package has been around for decades and
73    evolved from \MKII, to \MKIV\ and now \LMTX. The development
74    team has always been involved in the development of engines
75    like \PDFTEX, \LUATEX\ and \LUAMETATEX. There is an active
76    mailing list and there are \CONTEXT\ meetings.
