How can I remove all untracked files from an SVN checkout with the svn command line tool? Git and Hg offer clean and purge commands for this purpose, but I can't find the corresponding command in SVN.
I don't care if I have to revert all my local modifications in the process (in which case I'd essentially want to restore my checkout to a pristine state) or whether local modifications to tracked files can remain intact; either situation is acceptable.
