Subject: Re: equation numbering in html and latex export

Unfortunately this is not what jsMath expects. We get this in the html
file (see attached files for full source)
---
<p>This is what we want
$$
\label{eq:1}
y = ax + b
$$
</p>
<p>This is what we get
<div class="EQUATION">
\label{eq:1}
y = ax + b
</div>
</p>

What we need to do is to replace \begin{equation} ... \end{equation}
with $$ ... $$ in the HTML export. Any idea of how to do this?
