OOoMacros

OOoMacros: "ExtendedPDF is an OpenOffice.org macro that converts an OOo document into a PDF document. The output includes the original document's headings as PDF bookmarks, and includes the original hyperlinks as PDF hyperlinks. Document meta-information (such as title, author, and keywords) is also added. A user manual is available as a seperate download.
There is PDF creation support in OpenOffice.org. However, this is quite basic, and does not include support for hyperlinks or PDF bookmarks.

ExtendedPDF is developed by JDiSoftware. The open edition is released under the GNU General Public License (GPL). Commercial versions with extra features and full support are available from JDiSoftware."
