Notes on Writing Portable Programs in C: portableC.sty

[George V. Reilly]

% conf option for article.sty, created by DCH
% for Maths of Surfaces III, 15 May 89
% only modification: changing III to IV - AB 27 June 1990
%
% modified by ado at sauna.hut.fi for portable C notes.
% Everything was commented out except the page size definitions.
% If one uses art12.sty without these definitions it looks, well, stupid.
% One can format portableC.tex without this file; all you must do is
% remove the reference to portableC.sty in the \documentstyle command.
