% Cropmark.sty or .tex
% version 1.1 (minor enhancements see below)
%
% This will put crop marks on everythings that's \shipout'ed.
% It will work with any format, since it relies on redefinition
% of \shipout. Exception: if you declare \output{} you will
% not get crop marks.
%
% Cut along the center of the rules to get exactly the shipped
% out box. To get padding around this box, use the parameters below.
%
% User adjustable parameters:
% \croplength    length of the crop rules
% \cropwidth     width of the crop rules
% \cropsep       separation between rule and page box
% \croppadtop    padding in case page box looks bigger than it is
% \croppadbot    (for instance with plain TeX head/footline)
% \croppadlr
