Radreise-Wiki:DownloadRoute.pl

Das Perl-Skript downloadRoute.pl wird mit dem Streckennamen als Parameter aufgerufen. Ein Beispiel ist

perl downloadRoute.pl Rhein

Daraufhin loggt sich das Skript selbsttätig ins Wiki ein (Internetverbindung vorausgesetzt) und lädt den Source-Text der Strecke ins text-Verzeichnis.
