ReportLab vs. PDFLib for python?

[Johan]

Hi people,

Im right now building a application that will create an PDF file for
printing. (High-quality printing). The basic solutions is that I have build
a Service server in Python. It get some commands and will then create some
PDF files from the template that is requested.

But here I get the problem. I would love to use ReportLab, but I can't find
any way to import an existing PDF file into a other PDF file? Is it
possible? (Something like PDFLib's commercial PDI module?). Or do I have to
switch to PDFLib to get this?

I hope someone can help me :)

Regards,
Johan
