In less than ten minutes your Vim will transform into a beautiful
Haskell paradise. (Don't worry, it backs up your original
configuration.) It also builds all necessary support binaries
including codex, hscope, ghc-mod, hasktags, hoogle and more.
No more wading through plugins trying to make them all work together.
In ten minutes you will have a fully functional Vim that looks great
and lets you
inspect types
evaluate Haskell
lint and check
manipulate tags
hoogle lookup
pointfree refactor
tab compelete
unicode symbols
highlight DSLs
