Good Question there is a WoC Full Beta that has all modules except modules released on 10/11/2008. So depending on what you want to play you could add in just those modules you want with the core. Or if you want a full mod pack you could download the full modpack and add in the modules released on 10/11/2008. Here is the download link for the full modpack

HTML:
<Module>
<Directory>Units</Directory>
<bLoad>1</bLoad>
</Module>
TO
HTML:
<Module>
<Directory>Units</Directory>
<bLoad>0</bLoad>
</Module>
Setting anything to <bLoad>0</bLoad> will turn it off. There are several MLF's.
