Steps to reproduce:
1. Google search for "libreoffice import PDF"
2. Visit http://www.libreoffice.org/features/extensions/
3. It optimistically says
"Note that, in LibreOffice 3.3, many great extensions that were formerly separate downloads have now been included in the package as standard features:
PDF Import: the PDF Import extension ..."
But Ubuntu's packaging of LibreOffice *does not* include these extensions. Writer's Tools > Extension Manager lists only "Script provider for Python". In Ubuntu PDF import is a separate package, libreoffice-pdfimport , and best as I can tell this is not part of the default LO install.
Add a note to http://www.libreoffice.org/features/extensions/ e.g.
"Some Linux distributions provide these extensions separately; you can use your computer's package manager or software center to install them."
