Comment:

 I wrote a patch. Could you check if you see "GhostScript available" after
 applying it?

 It seems to me that hasn't been working for some time - I think I fixed
 GhostScript detection but other things might still be broken.

 One day, I'd like to simplify the Python runner - currently options are
 set via `-e`, then `config/ghc`, then `--config`; there are possible
 conflicts. Ideally, there should be one pass that reads the commandline
 and sets every option.
