I'm a long-time user of the pyPdf library, but now I'm having to work with
bigger volumes -- larger PDFs and thousands of them at a shot. So performance
is starting to become a problem.
Does anyone know of an analogue to pyPdf that is faster? (Maybe something
based on C with Python bindings?
just a note that the "Windows 2007 Server" is actually a "Windows 2008

I'm trying to get this invocation right, and it is escaping me. How
can I capture the stdout and stderr if I launch a subprocess using
