haskell.org libraries and tools page needs some fixing

[Neil Mitchell]

Hi,

> example, I think that http://www.haskell.org/haskellwiki/GUILibraries is

Thanks for all your work. Earlier there was a discussion about the
naming of pages, and it was specifically decided that names should be
something like:

Program_development

rather than:

ProgramDevelopment

The old wiki used to force CamelCase, but the new one doesn't, so
better named pages might help people.

Thanks

Neil
