    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 chmod -h 0700 /usr/libexec/cups/backend/cups-pdf
    sudo ln -sf #{share}/cups/model/CUPS-PDF.ppd /usr/share/cups/model/CUPS-PDF.ppd

    sudo mkdir -p /var/spool/cups-pdf/${USER}
    sudo chown ${USER}:staff /var/spool/cups-pdf/${USER}
    ln -s /var/spool/cups-pdf/${USER} ${HOME}/Documents/cups-pdf
    sudo killall -HUP cupsd

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