Sorry Kevin. :)

The version of wkhtmltopdf in Fedora right now does use system QT. However,
upstream also provides a heavily customised QT package that allows them to
provide considerably more functionality. From wkhtmltopdf --help:

================
Reduced Functionality:
  This version of wkhtmltopdf has been compiled against a version of QT without
  the wkhtmltopdf patches. Therefore some features are missing, if you need
  these features please use the static version.

  Currently the list of features only supported with patch QT includes:

 * Printing more then one HTML document into a PDF file.
 * Running without an X11 server.
 * Adding a document outline to the PDF file.
 * Adding headers and footers to the PDF file.
 * Generating a table of contents.
 * Adding links in the generated PDF file.
 * Printing using the screen media-type.
 * Disabling the smart shrink feature of webkit.
================

And this omits another key function: proper pagination.

Cumulatively, these features make wkhtmltopdf a full-featured PDF layout tool;
without them, the PDF output is not really any more sophisticated than
"printing" a long HTML page to PDF.

Of particular interest to Fedora docs people is the "Running without an X11
server" feature, which allows us to generate PDF at build-time in Koji. 

I'm certainly open to better ways of getting this functionality into Fedora,
though!

Cheers
Rudi
