synopsis:            A tiny lens library with no dependencies
description:
  NOTE: If you're writing an app, you probably want <http://hackage.haskell.org/package/microlens-platform microlens-platform> – it has the most features. <http://hackage.haskell.org/package/microlens microlens> is intended more for library writers who want a tiny lens library (after all, lenses are pretty useful for everything, not just for updating records!).
  .
  This library is an extract from <http://hackage.haskell.org/package/lens lens> (with no dependencies). It's not a toy lenses library, unsuitable for “real world”, but merely a small one. It is compatible with lens, and should have same performance. It also has better documentation.
  .
  There's a longer readme <https://github.com/stevenfontanella/microlens#readme on Github>. It has a migration guide for lens users, a description of other packages in the family, a discussion of other lens libraries you could use instead, and so on.
  .
  Here are some usecases for this library:
  .
    * You want to define lenses or traversals in your own library, but don't want to depend on lens. Having lenses available often make working with a library more pleasant.
  .
    * You just want to be able to use lenses to transform data (or even just use @over _1@ to change the first element of a tuple).
  .
    * You are new to lenses and want a small library to play with.
  .
  However, don't use this library if:
  .
    * You need @Iso@s, @Prism@s, indexed traversals, or actually anything else which isn't defined here (though some indexed functions are available elsewhere – containers and vector provide them for their types, and <http://hackage.haskell.org/package/ilist ilist> provides indexed functions for lists).
  .
    * You want a library with a clean, understandable implementation (in which case you're looking for <http://hackage.haskell.org/package/lens-simple lens-simple>).
  .
  As already mentioned, if you're writing an application which uses lenses more extensively, look at <http://hackage.haskell.org/package/microlens-platform microlens-platform> – it combines features of most other microlens packages (<http://hackage.haskell.org/package/microlens-mtl microlens-mtl>, <http://hackage.haskell.org/package/microlens-th microlens-th>, <http://hackage.haskell.org/package/microlens-ghc microlens-ghc>).
  .
  If you want to export getters or folds and don't mind the <http://hackage.haskell.org/package/contravariant contravariant> dependency, please consider using <http://hackage.haskell.org/package/microlens-contra microlens-contra>.
  .
  If you haven't ever used lenses before, read <http://hackage.haskell.org/package/lens-tutorial/docs/Control-Lens-Tutorial.html this tutorial>. (It's for lens, but it applies to microlens just as well.)
  .
  Note that microlens has no dependencies starting from GHC 7.10 (base-4.8). Prior to that, it depends on transformers-0.2 or above.
