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).")

    (description
     "MiniKanren is a relational programming extension to the Scheme
programming Language, written as a smaller version of Kanren suitable for
pedagogical purposes.  It is featured in the book, The Reasoned Schemer,
written by Dan Friedman, William Byrd, and Oleg Kiselyov.

This is Ian Price's r6rs packaged version of miniKranen, which deviates
slightly from miniKanren mainline.

See http://minikanren.org/ for more on miniKanren generally.")
