GNU Guile")
   (description
"Guile-Reader is a simple framework for building readers for GNU Guile.

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).")
