> One use case of DistCp is to sync two directories.  Currently, DistCp has an -update option for overwriting dst files if src is different from dst.  However, it is not enough for sync.  If there are some files in dst but not exist in src, there is no easy way to delete them.  We should add a new option, say -delete, so that DistCp will delete the non-existing in dst.
