I've decided to release my mapping application StarBase under the GPL.
It's a bit of a beast, so even just adding the license to each file, cleaning up the directory structure and making sure it's basically stable is non-trivial. I'm not ready to upload it to github yet, but if anyone wants a copy of the source in the meantime you're welcome. Maybe actually talking to people about it and answering questions might kick my arse into gear to get more done with it. Either of your world generation scripts should be adaptable into rules files for StarBase with a bit of work.
PM me and I'll send a link to a ZIP archive.
As a teaser, here's a link to the draft user guide:http://goo.gl/pPa4e
