% Name:
%	side.sty
% Purpose:
%	Include sideways (landscape) tables and figures in LaTeX documents
%	by defining new environments called sidetable and sidefigure.
%	Three options are available for placement along the width of the
%	printed page:
%		flush top		[t]
%		centered (default)	[c]
%		flush bottom		[b]
%	Standard LaTeX behavior (flush left) is preserved in the other
%	direction.
% Usage:
%	\documentstyle[side,...]{...}
%
%	\begin{sidetable}
%	  \caption{\label{mysidetable} A landscape floating table on a page.}
%	  \begin{center}
%	    \begin{tabular}{|l|c|}
%	  	\hline
%		Column1&Column2\\
%		Line1&\\
%		&Line2\\
%		\hline
%	    \end{tabular}
%	  \end{center}
%	\end{sidetable}
%
%	\begin{sidefigure}
%	  \hbox to \textheight{\hss \fbox{CENTERED FIGURE}\hss}
%	  \caption{\label{mysidefigure} A landscape floating figure on a page.}
%	\end{sidefigure}
% Restrictions:
%	Works only with PostScript.
%       Requires rotate.tex (part of dvips distribution)
% Modification History:
%	write, 17 Oct 91, F.K.Knight and M.F.Ryba, MIT Lincoln Laboratory
%	add placement options, 3 Dec 91, FKK
