+     "Fibers is a Guile library that implements a a lightweight concurrency
+facility, inspired by systems like Concurrent ML, Go, and Erlang.  A fiber is
+like a \"goroutine\" from the Go language: a lightweight thread-like
+abstraction.  Systems built with Fibers can scale up to millions of concurrent
+fibers, tens of thousands of concurrent socket connections, and many parallel
+cores.  The Fibers library also provides Concurrent ML-like channels for
+communication between fibers.
+
+Note that Fibers makes use of some Guile 2.1/2.2-specific features and
+is not available for Guile 2.0.")
