hevea.sty

% hevea  : hevea.sty
% This is a very basic style file for latex document to be processed
% with hevea. It contains definitions of LaTeX environment which are
% processed in a special way by the translator. 
%  Mostly :
%     - latexonly, not processed by hevea, processed by latex.
%     - htmlonly , the reverse.
%     - rawhtml,  to include raw HTML in hevea output.
%     - toimage, to send text to the image file.
% The package also provides hevea logos, html related commands (ahref
% etc.), void cutting and image commands.

\section{Introduction}\label{sec:intro}
This document has citations \citep{Ilg:2010vn}, using authoryear style
(\citealt{Wertheimer:1912aa}, \citeyear{Wertheimer:2012aa};
\citealp{Steinman:2000ap}). It should also have figure graphics and
internal references using cleveref or hyperref, such as the imminent reference
to \Xref{sec:graphics}.

\Xref{fig:label} has a picture in it, as was described in
\Xref{sec:intro} \citep{De-Valois:1991jt,Ramachandran:1990aa}.
