 Lwt is a library of cooperative threads implemented in monadic style.
 With respect to preemptive threads, cooperative threads are not using
 a scheduler to distribute processor time between threads. Instead of
 this, each thread must tell the others that he wants to let them
 work.

 This package contains the complete API reference for Lwt, including
 OpenSSL, GLib bindings and examples.
