 Aleph exposes data from the network as a [Manifold](https://github.com/clj-commons/manifold) stream, which can easily be transformed into a `java.io.InputStream`, [core.async](https://github.com/clojure/core.async) channel, Clojure sequence, or [many other byte representations](https://github.com/clj-commons/byte-streams).  It exposes simple default wrappers for HTTP, TCP, and UDP, but allows access to full performance and flexibility of the underlying [Netty](https://github.com/netty/netty) library.
