% This package is for using the aspect ratio symbol in math mode and in
% text mode by means of the command \AR.
%
% It is supposed to work both with LaTeX209 and LaTeXe
% It requires the METAFONT files ar5.mf, ar6.mf, ar7.mf, ar8.mf, ar9.mf,
% ar10.mf, ar12.mf
%
\ifx\documentclass\undefined
% With LaTeX209 the symbol is available in just one size (by default)
% but the user can edit the next line in order to get the size s/he wants
\newfont{\ar}{ar10 at 10pt}
\load{\normalsize}{\ar}
\def\AR{\mbox{\ar A}}
\else
% While with LaTeXe all standard sizes are available
% (no bold version available...sorry!)
