Recursive directory creation function. Like :func:`mkdir`, but makes all
intermediate-level directories needed to contain the leaf directory.
- The default *mode* is ``0o777`` (octal). On some systems, *mode* is
- ignored. Where it is used, the current umask value is first masked out.
+ The *mode* parameter is passed to :func:`mkdir`; see :ref:`the mkdir()
+ description <mkdir_modebits>` for how it is interpreted.
If *exist_ok* is ``False`` (the default), an :exc:`OSError` is raised if the
target directory already exists.
