Module documentation for 0.4.2.3

Lens
- Lens.Micro
  - Lens.Micro.TH

Depends on 6 packages(full list with versions):

base, containers, microlens, template-haskell, th-abstraction, transformers

Used by 15 packages in lts-14.27(full list with versions):

async-refresh, async-refresh-tokens, bitx-bitcoin, brick, butcher, cubicbezier, hledger-iadd, katip, microlens-platform, mmark, persistent-sqlite, plotlyhs, pushbullet-types, vty, web3

This package lets you automatically generate lenses for data types; code was extracted from the lens package, and therefore generated lenses are fully compatible with ones generated by lens (and can be used both from lens and microlens).

This package is a part of the microlens family; see the readme on Github.
