  ### Install the software.
  make DESTDIR="${pkgdir}" install

  ### 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 "${pkgdir}/usr/share/doc/wwwoffle/html"
  ln -sv "/var/spool/wwwoffle/html"/{de,en,es,fr,it,nl,pl,ru} "${pkgdir}/usr/share/doc/wwwoffle/html/"

  ### Install startup scripts for different init systems.
  install -D -m755 "${srcdir}/initscript_sysvinit" "${pkgdir}/etc/rc.d/wwwoffle"

  install -D -m644 "${srcdir}/initscript_systemd" "${pkgdir}/usr/lib/systemd/system/wwwoffle.service"

  ### Install a default initscript configuration file (for openrc and sysvinit only; for systemd user has to manually edit the systemd service file).
  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 ${install}-script.)
  sed -i -e 's/^#run-uid.*/ run-uid           = wwwoffle/' "${pkgdir}/etc/wwwoffle/wwwoffle.conf"
  sed -i -e 's/^#run-gid.*/ run-gid           = wwwoffle/' "${pkgdir}/etc/wwwoffle/wwwoffle.conf"

  ### Move config into final place (such that it is not automatically used, but user actually has to do some manual work).
  mv "${pkgdir}/etc/wwwoffle/wwwoffle.conf" "${pkgdir}/etc/wwwoffle/wwwoffle.conf.template"
