Can you add a blurb before the tree that describes what it shows? Does it make sense to also add an indication which ones are abstract types since the `Abstract*`...

Could run the app test inside a container with no Julia install. (Would still be the same machine, but at least paths etc that are built into the app will...

Logging goes to `stderr`, normally.

It is not set for Julia's sake, but I agree that it is a bit annoying to set since it makes different Julia version clash with each other. How about...

No, my suggestion should leave `LD_LIBRARY_PATH` identical to what it was before (unset if unset, populated if populated).
