Protocol Binary Helpers

[Reisen]

I'm planning to write protocol binaries in Haskell for IRC, Slack, etc. It would be nice to have a uniform interface for passing in configuration to these binaries, a walnut-binary of some sort would be useful to have. Something which provides:

• A common way of parsing configuration files.
• A common way of passing configuration arguments by command line.
• A common way of getting ZMQ details from the environment.
