-When you are finished with a DOM, you should clean it up. This is necessary
-because some versions of Python do not support garbage collection of objects
-that refer to each other in a cycle. Until this restriction is removed from all
-versions of Python, it is safest to write your code as if cycles would not be
-cleaned up.
-
-The way to clean up a DOM is to call its :meth:`unlink` method::
-
- dom1.unlink()
- dom2.unlink()
- dom3.unlink()
-
-:meth:`unlink` is a :mod:`xml.dom.minidom`\ -specific extension to the DOM API.
-After calling :meth:`unlink` on a node, the node and its descendants are
-essentially useless.

+When you are finished with a DOM tree, you may optionally call the

Decompresses the data in *string*, returning a string containing the
uncompressed data. The *wbits* parameter controls the size of the window
- buffer. If *bufsize* is given, it is used as the initial size of the output

+ If *bufsize* is given, it is used as the initial size of the output
buffer. Raises the :exc:`error` exception if any error occurs.
The absolute value of *wbits* is the base two logarithm of the size of the
history buffer (the "window size") used when compressing data. Its absolute
value should be between 8 and 15 for the most recent versions of the zlib
library, larger values resulting in better compression at the expense of greater
- memory usage. The default value is 15. When *wbits* is negative, the standard
+ memory usage. When decompressing a stream, *wbits* must not be smaller
+ than the size originally used to compress the stream; using a too-small
+ value will result in an exception. The default value is therefore the
+ highest value, 15. When *wbits* is negative, the standard
:program:`gzip` header is suppressed.
*bufsize* is the initial size of the buffer used to hold decompressed data. If
