Haskell in web browser/Haskell web toolkit

Haskell Web Toolkit (further referred to as HsWTK) is a thin layer built on top of DOM interfaces. It provides program interfaces to compose static layout of a web application page, and to hook up visual elements of an application to event handlers and XML HTTP communication means. HsWTK hides the low-level DOM APIs where possible; however their knowledge may be necessary to develop certain types of visual components and event handlers.
