-
-   Decorator to wrap a function with a memoizing callable that saves up to the
-   *maxsize* most frequent calls.  It can save time when an expensive or I/O
-   bound function is periodically called with the same arguments.
-
-   The *maxsize* parameter defaults to 100.  Since a dictionary is used to cache
-   results, the positional and keyword arguments to the function must be
-   hashable.
-
-   The wrapped function is instrumented with two attributes, :attr:`hits`
-   and :attr:`misses` which count the number of successful or unsuccessful
-   cache lookups.  These statistics are helpful for tuning the *maxsize*
-   parameter and for measuring the cache's effectiveness.
-
-   The wrapped function also has a :attr:`clear` attribute which can be
-   called (with no arguments) to clear the cache.
-
-   A `LFU (least frequently used) cache
-   <http://en.wikipedia.org/wiki/Cache_algorithms#Least-Frequently_Used>`_
-   is indicated when the pattern of calls does not change over time, when
-   more the most common calls already seen are the best predictors of the
-   most common upcoming calls (for example, a phonelist of popular
-   help-lines may have access patterns that persist over time).
