To my knowledge db2ps is the show-stopper - I only eats
Try the following - Note line no 2. with magic
<!doctype book PUBLIC "-//OASIS//DTD DocBook V3.1//EN" [
<!ENTITY % magic-entities SYSTEM "magic.sgml">
%magic-entities; <!-- This is where we include it -->
<!entity frihedendato SYSTEM "dato.sgml">
<!entity frihedenversion SYSTEM "version.sgml">
<!entity frihedenappendixRevHist SYSTEM "apprevhist.sgml">
I include three files here....
I have a makefile, where I do
echo '<!ENTITY magic "png">' > magic.sgml
if I output pdf or html
If I do ps-output, then I have
echo '<!ENTITY magic "eps">' > magic.sgml
Then I use ImageMagick to convert all my png-files to
eps if ps-output
find images/*.png | sed 's/.png//' | sed 's=images/==' | \
xargs -i% /usr/X11R6/bin/convert -antialias images/%.png eps2:bogps/%.eps

have the setup of the first makefile, then I works.
You can see a Makefile in
