;;; Commentary:
;;;
;;; This module provides an SXML pattern matcher, written by Jim Bender.  This
;;; allows application code to match on SXML nodes and attributes without having
;;; to deal with the details of s-expression matching, without worrying about
;;; the order of attributes, etc.
;;;
;;; It is fully documented in the Guile Reference Manual.
