<br>
there is actually documentation inside of EHFinder itself, eg:<br>

<a href="http://einsteintoolkit.org/documentation/ThornDoc/EinsteinAnalysis/EHFinder/" target="_blank">http://einsteintoolkit.org/<wbr>documentation/ThornDoc/<wbr>EinsteinAnalysis/EHFinder/</a><br>

and a pdf version is available via the<br>
