Moby is deprecated in favor of its successor, Whalesong.

Moby unfortunately didn't provide the performance I needed for
applications, so I needed to try a different approach.  Whalesong
takes a compile-to-Javascript approach that seems to perform a lot
better (on my benchmarks, at least 1000X faster), and it's where I'm
putting future development effort.
