A network connection establishment library

The conduit library takes care of establishing and listening for TCP and SSL/TLS connections for the Lwt and Async libraries.

The reason this library exists is to provide a degree of abstraction from the precise SSL library used, since there are a variety of ways to bind to a library (e.g. the C FFI, or the Ctypes library), as well as well as which library is used (just OpenSSL for now).

By default, OpenSSL is used as the preferred connection library, but you can force the use of the pure OCaml TLS stack by setting the environment variable CONDUIT_TLS=native when starting your program.

The useful opam packages available that extend this library are:

• conduit: the main Conduit module
• conduit-lwt: the portable Lwt implementation
• conduit-lwt-unix: the Lwt/Unix implementation
• conduit-async the Jane Street Async implementation
• conduit-mirage: the MirageOS compatible implementation
