A poor man's mkdir -p. Useful on old systems that don't have the -p option.
It won't work right if a target directory includes whitespace; tough luck.
Options:
-h print this info, then exit.
-oxxx chown xxx any created directory (put no space between -o and xxx).
-gxxx chgrp xxx any created directory (put no space between -g and xxx).
-pxxx chperm xxx any created directory (put no space between -p and xxx).
END
