svn mkdir — Create a new directory under version control.
Create a directory with a name given by the final
            component of the PATH or URL.
            A directory specified by a working copy
            PATH is scheduled for addition
            in the working copy.  A directory specified by a URL is
            created in the repository via an immediate commit.
            Multiple directory URLs are committed atomically.  In both
            cases, all the intermediate directories must already exist
            unless the --parents option is
            used.
