There is one thing that took me a while to understand when starting to use
that: This doesn't preserve your local changes. Instead, after uploading a new
upstream version, you have to apply your local changes again. Merging helps
though.

I agree. If you know Perl, you might come up with something different/better
or just more suitable for your case.

The at sign has a special meaning in SVN URL, it is used for peg revisions.
Question is, are there files with a trailing at sign in the tree that you want
to import? If yes, they are not handled correctly. If not, wrong filenames
have been generated at some point. It is probably a bug either in the import
script or SVN itself.

This looks strange. I know I had issues with virus scanners during imports,
but I never managed to fully explain why and when.

Those with the trailing "@"?

The script is checking out a working copy, then copying the version to be
imported over it. For any missing/added files, it then prompts you if those
were new file or if they were moved etc. It then performs the according "svn
add/move/delete" calls and commits the new version. It shouldn't be looking
for anything in already existing working copies - did you perhaps run it
inside a working copy?
