-   If *ignore_errors* is true, errors resulting from failed deletions will be
-   ignored. If *ignore_errors* is false or omitted, and a callable is given as
-   the optional *on_error* argument, it will be called with one argument of
-   type :exc:`OSError` each time an exception is raised. The callable can
-   handle the error to continue the deletion process or re-raise it to stop.

-      When deleting non-empty directories on platforms that lack the necessary
-      file descriptor-based functions, the :meth:`~Path.delete` implementation
-      is susceptible to a symlink attack: given proper timing and
-      circumstances, attackers can manipulate symlinks on the filesystem to
-      delete files they would not be able to access otherwise. Applications
-      can use the :data:`~Path.delete.avoids_symlink_attacks` method attribute
-      to determine whether the implementation is immune to this attack.
-
-   .. attribute:: delete.avoids_symlink_attacks
-
-      Indicates whether the current platform and implementation provides a
-      symlink attack resistant version of :meth:`~Path.delete`.  Currently
-      this is only true for platforms supporting fd-based directory access
-      functions.
