"Scribus (pasted from http://www.scribus.net/) is an open-source
program that brings award-winning professional page layout to
Linux/Unix, MacOS X, OS/2 and Windows desktops with a combination
of "press-ready" output and new approaches to page layout."

I am not involved or capable of being involved, but Scribus is an
excellent program with a devoted and highly competent community of
developers.

I have over the last year or so been contemplating my eventual need
for a CMS. I use Firebird as a backend for a major project I've been
developing for many years, as well as other smaller in-house
projects.

Scribus currently supports MySql (AFAIK), and is also apparently
attracting a wealth of interest via Google's Summer of Code.

Independently and in concert, I believe, with SoC, there appears to
be major interest in expanding Scribus into a CMS.

It would be a major loss (at least for me ;) if Scribus did not
provide access to Firebird.
