I ended up cherry-picking different parts from each implementation.
I liked David's changes to the read state machine to implement SASL.
I used Stephene's implementation of the binary protocol integrated with
the ASCII protocol.
This is extracted from another git repo. This is the first release, and
the prior commit history is not terribly interesting, so I'm not going
to bother using filter-branch to try to cleanly isolate the history for
this tool.
Cheers.
