Note that the front-end convenience tools the docbook-utils and sgml2x packages provide (the various docbook2* and docbook-2-* utilities such as docbook2html) are, like the older db2* utilities, (mostly) just scripts that act as "wrappers" around Openjade. So if you run into problems using the docbook2* or docbook-2-* or db2* wrapper scripts, you may want to consult the Openjade documentation and use Openjade directly instead.
