-
-The idea is to make it easy to build procedures that extend Guile’s read
-procedure.  Readers supporting various syntax variants can easily be written,
-possibly by re-using existing “token readers” of a standard Scheme
-readers.  For example, it is used to implement Skribilo’s R5RS-derived
-document syntax.
-
-Guile-Reader’s approach is similar to Common Lisp’s “read table”, but
-hopefully more powerful and flexible (for instance, one may instantiate as
-many readers as needed).")

-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
