%%
%% DESCRIPTION:
%% poster.tex/poster.sty contains a macro for making posters and banners
%% with TeX. It is compatible with most TeX macro packages, including Plain
%% TeX, LaTeX, AmSTeX, and Ams-LaTeX. The only special requirement is that
%% your printer not be bothered by text that lies off the page. This is
%% true of most printers, including laser printers and PostScript printers.
%%
%% COPYING:
%% This program can be redistributed and/or modified under the terms
%% of the LaTeX Project Public License Distributed from CTAN archives
%% in directory macros/latex/base/lppl.txt.
%%
%% CODE:
% These macros use TeX primitives, plus the Plain TeX commands:
% \dimen@, \dimen@i, \count@, \newcount, \newtoks,
%
% Check if file is loaded, announce file on terminal, and take care of @:
