herringbone is a Haskell library for compiling and serving web assets.
It aims to make it dead simple to create a 'Network.Wai.Middleware' or
'Network.Wai.Application' which deals with all of your static assets, including
preprocessing for languages like Fay, CoffeeScript, Sass, and LESS.

It takes most of its inspiration from the Ruby library,
<https://github.com/sstephenson/sprockets Sprockets>, hence the name.

Example:

> import Web.Herringbone
>
> fay, sass :: PP
>
> hb = Herringbone
> hb = herringbone
>     ( addSourceDir "assets"
>     . setDestDir   "compiled_assets"
>     . addPreprocessors [fay, sass]
>     )
>
> -- You can now access assets programmatically
> asset <- findAsset hb (fromJust . makeLogicalPath $ ["application.js"])
>
> -- Or serve them with a Wai application
> app = toApplication hb
