+synopsis: "An OCaml library for HTTP clients and servers"
+description: """
+Cohttp is an OCaml library for creating HTTP daemons. It has a portable
+HTTP parser, and implementations using various asynchronous programming
+libraries.
+
+See the cohttp-async, cohttp-lwt, cohttp-lwt-unix, cohttp-lwt-jsoo and
+cohttp-mirage libraries for concrete implementations for particular
+targets.
+
+You can implement other targets using the parser very easily. Look at the `IO`
+signature in `lib/s.mli` and implement that in the desired backend.
+
+You can activate some runtime debugging by setting `COHTTP_DEBUG` to any
+value, and all requests and responses will be written to stderr.  Further
+debugging of the connection layer can be obtained by setting `CONDUIT_DEBUG`
+to any value."""
