I wrote a TeXnicard export template for exporting to Multiverse. I intend to make the card set in TeXnicard, and only add a mirror to Multiverse (for the convenience of users who use Multiverse). If there are improvements to that template which could be made, then I hope that it can be done. If you see a bug in my program, you can report that, too.

It is my intention that the output from this export template can then be piped to curl (instead of xclip) in order to do this import.

Also I would hope for better documentation, for how to make adventurer cards, split cards, etc in the import. Maybe it might also be helpful to have a import format that can import other things too, all in one file, so that you can import mechanics and so on as well.
