svn cleanup — Recursively clean up the working copy
Recursively clean up the working copy, removing
            working copy locks and resuming unfinished operations.  If
            you ever get a working copy locked
            error, run this command to remove stale locks and get your
            working copy into a usable state again.
If, for some reason, an svn update
            fails due to a problem running an external diff program
            (e.g., user input or network failure), pass the
            --diff3-cmd to allow cleanup to complete
            any merging with your external diff program.  You can also
            specify any configuration directory with the
            --config-dir option, but you should need
            these options extremely infrequently.
