libcohttp-ocaml-dev 5.1.0-2build3 (amd64 binary) in ubuntu mantic

 Cohttp is an OCaml library for creating HTTP daemons. It has a
 portable HTTP parser, and implementations using various asynchronous
 programming libraries.
 .
 It has concrete implementations for many targets, including lwt,
 lwt-unix, lwt-jsoo.
 .
 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.
 .
 This package contains development files.
