Is there any existing library code to parse a DNS response in binary form?

[Jarrod Roberson]

I am writing a native erlang Bonjour / ZeroConf implementation and need to
parse the resulting binary DNS response I get.
Before I start down the road of bit syntax and all that I figured something
this fundamental had to already exist.
When I did a Python version of this there was already library code I could
use to parse the results.
I have searched Google and come up with nothing useful. Thanks in advance.
