By the way, I had trouble importing PDFs into Scribus 1.3.3. However,
Scribus 1.4.0rc3 had no problem opening multi-page PDFs, assuming the
appropriate Ghostscript was also installed (I'm on Windows 7 at the moment).
So Matthieu might be able to combine all of his figures into a single PDF,
convert to spot color in Scribus, then break the PDF apart again for Latex.
