There is a good library for communicating through AMQP protocol https://github.com/andersfugmann/amqp-client but its documentation too scarce (to the point of not existing at all) and examples are too basic. Searching through opam repository and GitHub revealed no projects using it. Is this ever used somewhere? I am searching for more practical examples of creating multiple queues in the application and publishing an answer as a response of processing those queues.
