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.")
