I'm pleased to announce Publican for openSUSE.

Publican is a Docbook publication system, not just a DocBook processing tool. As well as ensuring your DocBook XML is valid, publican works to ensure your XML is up to publishable standard.
Because upstream depreached FOP support and prefers wkhtmltopdf, this version comes without FOP package dependencies. If you want to use FOP, then deinstall wkhtmltopdf. After the next start publican will use FOP again.

More on: https://sourceware.org/publican/en-US/index.html.

How to install:

1. sudo zypper ar http://download.opensuse.org/repositories/Documentation:/Publican/openSUSE_Leap_42.2 (for openSUSE Leap 42.2) or
   sudo zypper ar http://download.opensuse.org/repositories/Documentation:/Publican/openSUSE_Tumbleweed (for openSUSE Tumbleweed)
2. sudo zypper in publican

On https://build.opensuse.org/project/show/Documentation:Publican you can find more packages, which names beginning with "publican-". That are brands for publican. You can use that brands, or can use it as base for your own brand.

Place Bugreports there.
