DraftSight - which version, to use with batch process?

Hi to all, we use another CAD to draw all our projects, but when we've to communicate with ours clients we've to use DWG format, for this reason we need a very basic program to make some basics command on dwg before sending it outside.

Basically we use purge and a batch script (scr extension).

Do you know if we can buy the Standard version of DraftSight, or we need to buy the Professional one? Do you also know if the overkill command is included in the standard version?

I searched a bit but I can't find any answer to my question.

Thanks and have a nice day.
