-- | A library and an executable that provide an easy API for a Haskell IDE
--   
--   Buildwrapper is an alternative to scion. It provides services to
--   configure, build and give information on source files to help IDEs
--   manage Haskell projects. You can use buildwrapper to build project and
--   retrieve errors, get outline for each module source, get the type of
--   something inside a source file, get lexer tokens, etc. Buildwrapper is
--   used in the EclipseFP project (Eclipse plugins for Haskell
--   development)
