+	<longdescription>
+		This package comes \&quot;Batteries Included\&quot; with many useful lenses for the types
+		commonly used from the Haskell Platform, and with tools for automatically
+		generating lenses and isomorphisms for user-supplied data types.
+		
+		The combinators in @Control.Lens@ provide a highly generic toolbox for composing
+		families of getters, folds, isomorphisms, traversals, setters and lenses and their
+		indexed variants.
+		
+		An overview, with a large number of examples can be found in the @README@: &lt;https://github.com/ekmett/lens#lens-lenses-folds-and-traversals&gt;
+		
+		A video on how to use lenses and how they are constructed is available from youtube: &lt;http://youtu.be/cefnmjtAolY?hd=1&gt;
+		
+		Slides can be obtained here: &lt;http://comonad.com/haskell/Lenses-Folds-and-Traversals-NYC.pdf&gt;
+		
+		More information on the care and feeding of lenses, including a brief tutorial and motivation
+		for their types can be found on the lens wiki: &lt;https://github.com/ekmett/lens/wiki&gt;
+		
+		A small game of @pong@ and other more complex examples that manage their state using lenses can be found in the example folder: &lt;https://github.com/ekmett/lens/blob/master/examples/&gt;
+		
+		/Lenses, Folds and Traversals/
+		
+		The core of the hierarchy of lens-like constructions looks like:
+		
+		
+		&lt;&lt;http://i.imgur.com/4fHw3Fd.png&gt;&gt;
+		
+		Local copy (&lt;Hierarchy.png&gt;)
+		
+		You can compose any two elements of the hierarchy above using @(.)@ from the @Prelude@, and you can
+		use any element of the hierarchy as any type it linked to above it.
+		
+		The result is their lowest upper bound in the hierarchy (or an error if that bound doesn&#39;t exist).
+		
+		For instance:
+		
+		* You can use any &#39;Traversal&#39; as a &#39;Fold&#39; or as a &#39;Setter&#39;.
+		
+		* The composition of a &#39;Traversal&#39; and a &#39;Getter&#39; yields a &#39;Fold&#39;.
+		
+		/Minimizing Dependencies/
+		
+		If you want to provide lenses and traversals for your own types in your own libraries, then you
+		can do so without incurring a dependency on this (or any other) lens package at all.
+		
+		/e.g./ for a data type:
+		
+		&gt; data Foo a = Foo Int Int a
+		
+		You can define lenses such as
+		
+		&gt; -- bar :: Lens&#39; (Foo a) Int
+		&gt; bar :: Functor f =&gt; (Int -&gt; f Int) -&gt; Foo a -&gt; f (Foo a)
+		&gt; bar f (Foo a b c) = fmap (\a&#39; -&gt; Foo a&#39; b c) (f a)
+		
+		&gt; -- baz :: Lens (Foo a) (Foo b) a b
+		&gt; quux :: Functor f =&gt; (a -&gt; f b) -&gt; Foo a -&gt; f (Foo b)
+		&gt; quux f (Foo a b c) = fmap (Foo a b) (f c)
+		
+		without the need to use any type that isn&#39;t already defined in the @Prelude@.
+		
+		And you can define a traversal of multiple fields with &#39;Control.Applicative.Applicative&#39;:
+		
+		&gt; -- traverseBarAndBaz :: Traversal&#39; (Foo a) Int
+		&gt; traverseBarAndBaz :: Applicative f =&gt; (Int -&gt; f Int) -&gt; Foo a -&gt; f (Foo a)
+		&gt; traverseBarAndBaz f (Foo a b c) = Foo &lt;$&gt; f a &lt;*&gt; f b &lt;*&gt; pure c
+		
+		What is provided in this library is a number of stock lenses and traversals for
+		common haskell types, a wide array of combinators for working them, and more
+		exotic functionality, (/e.g./ getters, setters, indexed folds, isomorphisms).
