ghc-haddock binary package in Ubuntu Trusty i386

 Haddock is a tool for automatically generating documentation from
 annotated Haskell source code. It is primary intended for documenting
 libraries, but it should be useful for any kind of Haskell code.
 .
 Haddock lets you write documentation annotations next to the
 definitions of functions and types in the source code, in a syntax
 that is easy on the eye when writing the source code (no heavyweight
 mark-up). The documentation generated by Haddock is fully hyperlinked:
 click on a type name in a type signature to go straight to the
 definition, and documentation, for that type.
 .
 Haddock can generate documentation in multiple formats; currently HTML
 is implemented, and there is partial support for generating DocBook.
 .
 This package contains Haddock version 2.10.0.
