    In order to use cups-pdf with the Mac OS X printing system change the file
    permissions, symlink the necessary files to their System location and
    have cupsd re-read its configuration using:

    chmod 0700 #{(lib+'cups/backend')}/cups-pdf
    sudo chown root #{(lib+'cups/backend')}/cups-pdf
    sudo ln -sf #{(etc+'cups')}/cups-pdf.conf /etc/cups/cups-pdf.conf
    sudo ln -sf #{(lib+'cups/backend')}/cups-pdf /usr/libexec/cups/backend/cups-pdf
    sudo ln -sf #{(share+'cups/model')}/CUPS-PDF.ppd /usr/share/cups/model/CUPS-PDF.ppd
    sudo killall -HUP cupsd

    NOTE: When uninstalling cups-pdf these symlinks need to be removed manually.
