Enats is an minimal erlang client module for connecting to a NATS Pub/Sub server.  It uses jsonerl's record_to_json and json_to_record for the communication that involve JSON.

General Usage:
Copy enats_client.erl, enats_raw_connection.erl and jsonerl.erl to your /src directory.  Copy jsonerl.hrl and enats_records.hrl to your /include directory.

Create client
enats_client:start_link().
Initialize connection
enats_client:connect({"localhost", 4222}, {"username", "password"}).
Subscribe to a subject
Sid = enats_client:subscribe("scooby.doo", fun (Subject, Message) -> io:format("Subject: ~s~nMessage: ~s~n", [Subject, Message]) end).
Publish a message
enats_client:publish("scooby.doo", "Where are you?").
Disconnect from the server
enats_client:disconnect().
