I wouldn't have expected this to be a situation that would occur
often enough to warrant creating a script.
Maybe you're using externals more frequently than I, but I would just
make it a policy that developers shall not move, rename or delete a
directory that is shared code used by other projects. No, Subversion
doesn't provide a list of such places, but maybe the item's name or
its location in the repository would give a clue. For example, if all
your shared code is in a directory called "shared" then developers
should know not to move/rename/delete those items as they're probably
in use elsewhere.
You could create your own database of externals. Yes, you'd have to
crawl the entire repository, examining all directories for their
svn:externals property, to build the initial database, but then you
could use a post-commit hook to keep it up to date as the repository
changes revision by revision, which shouldn't be too bad. Then you
can make that database available to developers so they can know
what's where, and/or you can implement a hook script. I wouldn't try
to automate making a copy of the code, as you suggested; I'd instead
fail the commit if the developer tries to move/rename/delete
something that's in use elsewhere.
