%C details.

%D This style is used for producing explanationary documents. Don't misuse it for
%D other purposes, since it may confuse users. Don't change the title either, since
%D it provides a way to categorize documents. Numbers are disabled in instances
%D produced outside PRAGMA ADE.
%D
%D The layout setup is such that one has several text areas available: headers and
%D footers, margins and edges as well as the main text area. The surrounding (gray)
%D makes the main page stand out and is suitable for viewing in spread mode.
%D
%D Since this style is under constant construction, messing around with settings
%D will produce unwanted side effects. So, if some feature or settings is needed,
%D let me know.

%D By now (2019) it's an old style that needs an overhaul ...

This is the zero issue of a range of \CONTEXT\ related publications, in most
cases short introductions to new functionality. The style may be used by users
for providing similar documents, but preferably not for other purposes, since it
may confuse readers in their expectations.

We've chosen a layout which is more functional than beautiful. This layout
provides several text areas: headers and footers, margins and edges as well as a
main text area. The surrounding (gray or color) makes the main page (which is
slightly smaller than A4) stand out and is suitable for viewing in spread mode.

The documents produced at \PRAGMA\ are called {\bf This Way}, user documents gets
the title {\bf My Way}. The \PRAGMA\ issues are numbered. We strongly advise you
not to use the \type {mag-} prefix for your issues, since this may lead to
clashes with files distributed by \PRAGMA.
