NAME

       hoogle - A Haskell API search engine.

SYNOPSIS

       hoogle EXPRESSION|COMMAND [OPTIONS]

DESCRIPTION

       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.
