Hey folks, is

build_file_aliases

undocumented? and is that intentional?

Hmm, I don't think it's intentional? Looks like a bunch of backends use it

neato. I was looking into it as a way to provide git information (ticket), and couldn't find anything on it. I'm not sure that approach will work: the class that provides git information needs to run rules (to locate git, among other), but I think a BUILD file would need that before any rules can run.
