# Haddock ![CI][CI] [![Hackage][Hackage badge]][Hackage page]

Haddock is the standard tool for generating documentation from Haskell code.
Full documentation about Haddock itself can be found in the `doc/` subdirectory,
in [reStructedText format][ReST] format.

## Project overview

This project consists of three packages:

 * `haddock`: provides the `haddock` executable. It is implemented as a tiny
    wrapper around `haddock-api`'s `Documentation.Haddock.haddock` function.

 * `haddock-api`: contains the program logic of the `haddock` tool.
   [The haddocks for the `Documentation.Haddock` module][Documentation.Haddock]
   offer a good overview of the functionality.

 * `haddock-library`: is concerned with the parsing and processing of the
   Haddock markup language. Unlike the other packages, it is expected to build
   on a fairly wide range of GHC versions.
