[Scribus] Automatic export to png?

[Frank Cox]

Is it possible (would it be possible?) to make Scribus automatically
load a .sla file and export the contents to png images?

I create a weekly subsribers-only web page for the Bargain Hunter
containing the current paper, and have managed to script every part of
the page building and uploading process except for the initial export
to png images step which requires that I sit here and do that part
manually.

If I could automate that part too, the whole process should just run on rails.

(Incidentally, for anyone who has a web page to keep updated, I highly
recommend http://www.lyra.org/sitecopy/, which is a truly valuable
utility for webmasters.)
