description:
    This package comes \"Batteries Included\" 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 <https://github.com/ekmett/lens#lens-lenses-folds-and-traversals README>.
    .
    An introductory video on the style of code used in this library by Simon Peyton Jones is available from <http://skillsmatter.com/podcast/scala/lenses-compositional-data-access-and-manipulation Skills Matter>.
    .
    A video on how to use lenses and how they are constructed is available on <http://youtu.be/cefnmjtAolY?hd=1 youtube>.
    .
    Slides for that second talk can be obtained from <http://comonad.com/haskell/Lenses-Folds-and-Traversals-NYC.pdf comonad.com>.
    .
    More information on the care and feeding of lenses, including a brief tutorial and motivation
    for their types can be found on the <https://github.com/ekmett/lens/wiki lens wiki>.
    .
    A small game of @pong@ and other more complex examples that manage their state using lenses can be found in the <https://github.com/ekmett/lens/blob/master/examples/ example folder>.
    .
    /Lenses, Folds and Traversals/
    .
    With some signatures simplified, the core of the hierarchy of lens-like constructions looks like:
    .
    .
    <<http://i.imgur.com/ALlbPRa.png>>
    .
    <Hierarchy.png (Local Copy)>
    .
    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'\''t exist).
    .
    For instance:
    .
    * You can use any '\''Traversal'\'' as a '\''Fold'\'' or as a '\''Setter'\''.
    .
    * The composition of a '\''Traversal'\'' and a '\''Getter'\'' yields a '\''Fold'\''.
    .
    /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:
    .
    > data Foo a = Foo Int Int a
    .
    You can define lenses such as
    .
    > -- bar :: Lens'\'' (Foo a) Int
    > bar :: Functor f => (Int -> f Int) -> Foo a -> f (Foo a)
    > bar f (Foo a b c) = fmap (\a'\'' -> Foo a'\'' b c) (f a)
    .
    > -- quux :: Lens (Foo a) (Foo b) a b
    > quux :: Functor f => (a -> f b) -> Foo a -> f (Foo b)
    > quux f (Foo a b c) = fmap (Foo a b) (f c)
    .
    without the need to use any type that isn'\''t already defined in the @Prelude@.
    .
    And you can define a traversal of multiple fields with '\''Control.Applicative.Applicative'\'':
    .
    > -- traverseBarAndBaz :: Traversal'\'' (Foo a) Int
    > traverseBarAndBaz :: Applicative f => (Int -> f Int) -> Foo a -> f (Foo a)
    > traverseBarAndBaz f (Foo a b c) = Foo <$> f a <*> f b <*> 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).
