    (description "@code{guile-chibi-match} is a portable hygienic
pattern matcher for Scheme.  This is a full superset of the popular
match package by Andrew Wright, written in fully portable syntax-rules
and thus preserving hygiene.  The most notable extensions are the
ability to use non-linear patterns---patterns in which the same
identifier occurs multiple times, tail patterns after ellipsis, and
the experimental tree patterns.")
