  ### Move documentation into the place we want it.
  mkdir -p "${pkgdir}/usr/share"
  mv -v "${pkgdir}/usr/doc" "${pkgdir}/usr/share/doc"

  ### Symlink the HTML-Documentation under wwwoffle's spool directory to the documentation directory. Note: The html documentation needs to stay at wwwoffle's spool directory, since it serves it from there when it's webinterface is accessed.
  mkdir -p "${pkgdir}/usr/share/doc/wwwoffle/html"

  install -D -m644 "${srcdir}/conf_d_wwwoffle" "${pkgdir}/etc/conf.d/wwwoffle"

  ### Change config such that wwwoffle runs as user wwwoffle and group wwwoffle. (Adding user and group is handled by the ${install}-script.)

  mv "${pkgdir}/etc/wwwoffle/wwwoffle.conf" "${pkgdir}/etc/wwwoffle/wwwoffle.conf.template"

  ### Install contrib(uted) scripts and files for the user's disposal
  cp -av "${srcdir}/${_pkgname}"/{contrib,contrib-win32,doc/scripts} "${pkgdir}/usr/share/doc/wwwoffle/"

  ### Set permissions of spool directory.
  chmod -R ug=Xwr "${pkgdir}/var/spool/wwwoffle"
