Nice work, Kovid! I was testing this out before the release.
Ran into some initial trouble

trying to deposit my test libraries inside the temporary folder I created for the configuration data, no libraries actually got created. I am not really sure that that is a bug per se...
Other than that it looks great!

(@BetterRed, no need for me to edit the FAQ now.

I really was going to, but Kovid's edit is better...)
