Jason suggested that it should create just:


by default. This is now what mkcabal does. So you can use it to generate
stub .cabal files for existing projects.

    $ runhaskell mkcabal.hs
    Project name: x
    Created Setup.hs and x.cabal

For entirely new projects, mkcabal --init-project
creates an entire new project tree.

    $ runhaskell mkcabal.hs --init-project
    Project name: ruby-on-rails-killer
    Created new project directory: ruby-on-rails-killer

    $ ls ruby-on-rails-killer 
    LICENSE                           Ruby-on-rails-killer.hs
    README                            Setup.hs

Further wishlists would be for the default to scan for src files to
populate the .cabal file with, and to distinguish libraries from
