        Maybe, but that doesn't help people that have to deal with them.

        Furthermore, Mac OS X doesn't actually use resource forks any more, it
emulates them with extended attributes, which are available in many
other operating systems. So it is a pretty unfortunate that Subversion
doesn't properly handle them.
