666
gets used in extracting all members from every zipfile specified on the
667
command line. Note that under FlexOS, if a candidate extract-to
668
directory specification includes a drive letter (leading "x:"), it is
669
treated just as if it had a trailing '/'--that is, one directory level
670
will be created if the path doesn't exist, unless this is otherwise pro-
671
hibited (e.g., freshening).
