The text is written by Ton Otten and Hans Hagen and the
illustrations and photographs are drawn and taken by Johan
Jonker. The overall layout of this manual is adapted to
{\em Baskerville}. Thanks to Sebastian Rahtz for his positive
input. 

The original manual has about 1000 random generated
\METAPOST\ graphics and looks a bit less formal. One can
upload a version meant for printing as well as one for
viewing on the screen from \type{www.ntg.nl/context}. The
public part of the sources of \CONTEXT\ can be found at the
same location. 

We're currently updating the Dutch reference manual, which
will also be available in English and German. The latest
quick reference documents, as well as some example
documents, can be downloaded from the site mentioned.

  I first realised that Hans Hagen had something
  rather special in the way of a macro package when he talked about
  his PDF work at the 1995 Euro\TeX\ meeting in Arnhem. But it was not
  until I saw a serious demonstration of \CONTEXT\ at the 1997 TUG
  meeting in San Francisco that the scale and sophistication of the
  package became apparent. After Hans talked about his work at the
  1997 UKTUG meeting, my respect increased, and we started to talk in
  the UKTUG committee about putting something substantial into
  {\em Baskerville} for our members. This double issue is the result,
  a complete introduction to \CONTEXT, to complement the macros which are
  already available on the \TeX\ Live CD-ROM.
\vskip2pt
  \CONTEXT\ is a macro package. It does the same job as \LaTeX, but
  the setup is very different. \LaTeX\ consists of a core, a
  set of `official' document classes, and a set of interface
  conventions;  the rest is composed of
  packages contributed by hundreds of people over the last 15 years.
  The result is hugely powerful, but chaotic, and on the verge
  of becoming unmanageable. \CONTEXT\ is different; all the facilities
  you need are provided up front, there is no system of
  user-contributed packages. The code is all maintained and controlled
  by Hans Hagen and his small company, and you do not need to worry
  about having to go off and look for that extra \LaTeX\
  package. \CONTEXT\ was {\em designed} to include most of the
  facilities which \LaTeX\ accumulated over the years. There are no
  `document classes', just an enormously powerful set of commands to
  define the formatting of your document.
\vskip2pt
  What you are about to read is, I must stress, an {\em Introduction};
  the full reference manual is currently only in Dutch, but it is in
  the process of being translated. It contains details of many more
  commands whose existence is only hinted at here.
\vskip2pt
  Obviously we needed to make this manual look as much like the {\em
  Baskerville} style as we could; Hans did most of the work, but
  Robin Fairbairns, Malcolm Clark and I
  had a sudden baptism by fire of \CONTEXT\ when we decided to try and
  massage the text into double columns. {\em Do not blame Hans or
  \CONTEXT\ for the results!} 
\vskip2pt
  A word of warning to those who want to rush straight off and try out
  this package: it is {\em big}. It eats \TeX\ memory like there is
  no tomorrow, and you cannot expect to run it on a small \TeX\
  implementation. Persevere: all modern \TeX\ implementations can
  increase their memory size. You may have to experiment a bit to get
  things working.
