    function for :keyword:`with` statement context managers, without needing to
    create a class or separate :meth:`__enter__` and :meth:`__exit__` methods.
 
-   A simple example (this is not recommended as a real way of generating HTML!)::
+   While many objects natively support use in with statements, sometimes a
+   resource needs to be managed that isn't a context manager in its own right,
+   and doesn't implement a ``close()`` method for use with ``contextlib.closing``
+
+   An abstract example would be the following to ensure correct resource
+   management::
 
       from contextlib import contextmanager
 
       @contextmanager
-      def tag(name):
-          print("<%s>" % name)
-          yield
-          print("</%s>" % name)

+          try:
+              yield resource
+          finally:

+      >>> with managed_resource(timeout=3600) as resource:

    The function being decorated must return a :term:`generator`-iterator when
    called. This iterator must yield exactly one value, which will be bound to
