The used rsync command only updates files, but doesn't delete no longer existing files on the destination.
Thus pages like http://pingus.seul.org/press.html still exist although it has long ago been renamed to links.html
Normally I would just add the --delete flag but currently the destination htdocs folder holds an unknown amount of files (e.g. todo/, development/ and levels/ folders, other html pages, images, ...) which are not in the repository and thus would get delete.
If some of them are potentially still of interest they should probably be saved somehow or another way should be found to remove "no longer existing" files
