hoogle - A Haskell API search engine.

       The text for this page was constructed from the Hoogle search engine's web page and written  by  Erik  de
       Castro Lopo <erikd@mega-nerd.com> and Kiwamu Okabe <kiwamu@debian.or.jp>, for the Debian GNU/Linux system
       (but may be used by others).

       Hoogle  is  a  Haskell  API search engine which allows you to search Haskell libraries by either function
       name, or by approximate type signature.
       Example searches with EXPRESSION:

           map
           (a -> b) -> [a] -> [b]
           Ord a => [a] -> [a]
           Data.Map.insert

       The Hoogle manual (http://www.haskell.org/haskellwiki/Hoogle) contains more  details,  including  further
       details  on  search  queries,  how  to  install Hoogle as a command line application and how to integrate
       Hoogle with Firefox/Emacs/Vim etc.

       This program also has some command for special usage.
