% CAP --- Macros for typesetting programs in C and Pascal %
% Micha\l{} Gulczy\'nski, Szczecin, Feb 1997 / Feb 1998 %
% mgulcz@we.tuniv.szczecin.pl %
+% Some (non-essential) changes to support COLORDVI output %
+% Danilo \v Segan, Beograd, Sep 2002 %
+% mm01142@alas.matf.bg.ac.yu %
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%
+% version 1.2d
+% Added DVIPS color support (actually, any output is replaced with
+% a macro call to \Ispis --- search for it to see the changes)
+% Also extended a mechanism for marking "special" symbols, so they
+% would get applicable color in a string, comment, or otherwise
+% NOTE: It should be backwards compatible, so there is no need to
+% change anything else, except of course adding color
+% settings if you wish
+% -- by Danilo {\v S}egan, mm01142@alas.matf.bg.ac.yu
% version 1.2
% This file contains common definitions used in the CAP package.
% It does not contain any useful macros itself.
%
+% If you don't have dvips's colordvi.tex, then fetch it from somewhere
+% to avoid errors in processing (it inserts specials which will
+% probably be ignored by anything other than COLORDVI aware software)
+% The alternate solution is to comment out all color definitions
+% (\let's) and to define writeout function as \def\Ispis#1{#1}
+\input colordvi
+
+% If you don't have color printer, you may choose to remain compatible
+% with those that do, and only use analogous dvips's input file
+%\input blackdvi
