<h2><a name='sect2' href='#toc2'><b>Description</b></a></h2>
<p>
The obgen tool will generate 3D coordinates for molecules in a file
(e.g. multi-molecule SMILES files). The resulting structure will be
optimized using the given forcefield and checked for the
lowest-energy conformer using a Monte Carlo search.
Output will be sent to standard output in the SDF file format.
<p>
<h2><a name='sect3' href='#toc3'><b>Options</b></a></h2>
<p>
If no filename is given, obminimize will give all options including the
available forcefields.
