Since we've moved to a newer version of Tika, we've had on-and-off trouble (mostly on!) with aut working with --packages. The current state yields this:

I see two options:

1. We support it.

I can dive back into dependency tree, and do a lot of pom.xml surgery again to see if I can get us to a state to run --packages again. Last time I tried this with the two 3.0.0 previews, the results were not fruitful, and I'm highly doubtful I can get it work again.

2. We don't support it.

aut can be loaded by Spark to driver and executor classpaths with --jars.

If we go with option 2 (which is my preference), I'll work on getting the documentation updated.
