Is there a way to perform a SVN checkout (or export), which would fetch only the directory structure; that is to say, no files?
svn ls -R {svnrepo} | grep "/$" | xargs -n 1 mkdir -p
Export, not a checkout.
[Updated]
With checkout:
env REPO={repo} sh -c 'svn ls -R $REPO | grep "/\$" | xargs -n 1 svn co --depth=empty $REPO'
This will be pretty slow for anything too large.
