-- | Main module for defining Shake build systems. You may also want to include
--   "Development.Shake.FilePath", for manipulating file paths. As a simple example,
--   let us build a @result.tar@ file from the contents of @result.txt@:
--
-- @
--import "Development.Shake"
--import "Development.Shake.FilePath"
--
--main = 'shake' 'shakeOptions' $ do
--    'want' [\"result.tar\"]
--    \"*.tar\" *> \\out -> do
--        contents <- 'readFileLines' $ replaceExtension out \"txt\"
--        'need' contents
--        'system'' \"tar\" $ [\"-cf\",out] ++ contents
-- @
