| 27 | ;;; Commentary: |
| 28 | ;;; |
| 29 | ;;; This module provides an SXML pattern matcher, written by Jim Bender. This |
| 30 | ;;; allows application code to match on SXML nodes and attributes without having |
| 31 | ;;; to deal with the details of s-expression matching, without worrying about |
| 32 | ;;; the order of attributes, etc. |
| 33 | ;;; |
| 34 | ;;; It is fully documented in the Guile Reference Manual. |
