%C details.

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