cygnus-stylesheets obsolete

[Christian Marillat <marillat.christian@wanadoo.fr>]

Hi,

The new package docbook-utils has been installed yesterday, and this
package replace cygnus-stylesheets.

I'll do a cygnus-stylesheets package today who only depends on
docbook-utils.

Maintainers need to replace cygnus-stylesheets by docbook-utils in
Build-Depends.

For packages who are using the DocBook PNG Variant, Mr Bean
<jules@debian.org> will package gnome-doc-tools.
