 ..  function:: cmp_to_key(func)
 
-    Transform an old-style comparison function to a key-function.  Used with
-    tools that accept key functions (such as :func:`sorted`, :func:`min`,
-    :func:`max`, :func:`heapq.nlargest`, :func:`heapq.nsmallest`,
-    :func:`itertools.groupby`).
-    This function is primarily used as a transition tool for programs
-    being converted from Py2.x which supported the use of comparison
-    functions.
-
-    A compare function is any callable that accept two arguments, compares
-    them, and returns a negative number for less-than, zero for equality,
-    or a positive number for greater-than.  A key function is a callable
-    that accepts one argument and returns another value that indicates
-    the position in the desired collation sequence.
-
-    Example::
-
-        sorted(iterable, key=cmp_to_key(locale.strcoll))  # locale-aware sort order
