+% A Class for those who care about brazilian rain forests
+% Copyright (C) Moshe Zadka, 1998
+% I wish to thank the LaTeX3 team, who provided the original ``article.cls''
+% file, which I hacked so it would allow 7pt size.
+%
+% I also wish to thank the authors of the xarticle package, which was the
+% typographical inspiration.
+%
+% This file is supposed to comply with LaTeX3 copyright restrictions:
+% I'm renaming the file, and clearly saying that I modified it, and that
+% I am responsible for its contents.

+% \title{A New Article-Like Class}
+% \author{Moshe Zadka\thanks{moshez@math.huji.ac.il}}
+% \maketitle
+%
+% \section{Introduction}
+% 
+% Finding size options for 10pt, 11pt, and 12pt, I was annoyed having no
+% package file for supporting a smaller point size. I took the typographical
+% guidelines from the old \LaTeX\ 2.09 package |xarticle|.

+% Put |\documentclass[...]{viiptart}| as the first line of your document.
+% Options are the same as in the standard \LaTeXe\ |article| class.

+% \section{Code From {\tt article.cls}}
+%
+% This code was copied almost entirely from the |article.cls| file in the
+% \LaTeXe\ distribution.
+% The only changes I made was to delete the option processing for point
+% size, and the |sizexx.clo| loading code.
