ANTLR-Rust: anybody tried it out?

I haven't tried it yet, but looking over the documentation, I couldn't find any step-by-step instructions for ANTLR newbies. I'm somewhat experienced in Rust, and plan to try to get it working, but figured I'd ask first in case I missed some crucial documentation.

I realize it's "brand new, hot off the presses, likely buggy" and all. Just want to get a feel for how it's coming along since someday I would want to use it.
