Probably I'm one of those, then! At least sometimes. ;-)

As Marco said, you can do some interesting stuff using pyPDF. I'm
using it in some overview tools of mine, see table below (with my
own code for stuff like the number of images). If you want to
verify the figures, google for the filenames... ;-)

Of course, there is even more interesting stuff like extracting
content for verification, etc. I've done this for images. And
even cooler stuff can be done when you analyse the PDF structure.
I'm attaching a short example as illustration (open the .dot file
with GraphViz).

All this isn't quite finished, but very promising...
