> 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.
