It is part of rabbitmq, which I'm guessing it's reasonable to call *fairly
stable and production worthy* lol. I keep a copy as a standalone OTP
library application on github, which I update/synchronise periodically with
updates from the rabbit hg/git repository. I haven't refreshed it in a
while, as we're largely >= R14 now, but I find this approach (of bundling
it as a standalone library app) works nicely for making it available across
projects, though I'm less reliant on it now as I'm not using the extra
features it provides in addition to message queue draining.
