 by a weak reference.
 
 A weak reference to an object is not enough to keep the object alive: when the
-only remaining references to a referent are weak references, garbage collection
-is free to destroy the referent and reuse its memory for something else.  A
-primary use for weak references is to implement caches or mappings holding large
-objects, where it's desired that a large object not be kept alive solely because
-it appears in a cache or mapping.  For example, if you have a number of large
-binary image objects, you may wish to associate a name with each.  If you used a
-Python dictionary to map names to images, or images to names, the image objects
-would remain alive just because they appeared as values or keys in the
-dictionaries.  The :class:`WeakKeyDictionary` and :class:`WeakValueDictionary`
-classes supplied by the :mod:`weakref` module are an alternative, using weak
-references to construct mappings that don't keep objects alive solely because
-they appear in the mapping objects.  If, for example, an image object is a value
-in a :class:`WeakValueDictionary`, then when the last remaining references to
-that image object are the weak references held by weak mappings, garbage
-collection can reclaim the object, and its corresponding entries in weak
-mappings are simply deleted.

 This approach works fine for most applications but occasionally there is a need
 to track objects only as long as they are being used by something else.
