My version of automated checking - I use a linux server, with XVFB configured to reduce the X interaction from Stars!

<primo code>

Basically plots a text grid (see the xrange and yrange parameters) of the universe, wth just the HWs marked.
I do have one that marks secondaries as well (although not their affiliation).

Allows for some serious automation - you could use the p files to verify the mineral concentrations are as you want to find as well.
