     "PDFmarks is a technique that accompanies PDF, and that is used to store
metadata such as author or title, but also structural information such as
bookmarks or hyperlinks.

When Ghostscript reads the main PDF generated by the TeX system with embedded
PDF files and outputs the final PDF, the PDF page mode and name targets
etc. are not preserved.  Therefore, when you open the final PDF, it is not
displayed correctly.  Also, remote PDF links do not work correctly.

This program is able to extract the page mode and named targets as PDFmark
from PDF.  In this way, you can obtain embedded PDF files that have kept this
information.")

From a technical point of view, WeasyPrint is a visual rendering engine for
HTML and CSS that can export to PDF and PNG.  It aims to support web standards
for printing.

It is based on various libraries but not on a full rendering engine like
WebKit or Gecko.  The CSS layout engine is written in Python, designed for
pagination, and meant to be easy to hack on.  Weasyprint can also be used as a
python library.
