+Synopsis:               Happy Haskell programming on Emacs
+Description:            This packages includes Elisp files
+			and a Haskell command, "ghc-mod".
+			"ghc*.el" enable completion of
+			Haskell symbols on Emacs.
+                        Flymake is also integrated.
+			"ghc-mod" is a backend of "ghc*.el".
+			It lists up all installed modules
+                        or extracts names of functions, classes,
+                        and data declarations.
