The docbook-utils is a set of a few small programs intended to ease
everyday's use of technical documentation software and more generally
use of SGML and XML. They are released under the GPL licence.

Tasks they currently accomplish are:
  - jw: convert SGML files to other formats (HTML, RTF, Postscript, PDF)
  - sgmldiff: detect the differerences in markup between two SGML files
