Description:
    The rspec:skeleton generator creates a standard skeleton directory/file structure for using Rspec in a Rails 3 app.

Example:
    ./script/generate rspec:skeleton

    This will create the following directory structure inside the root of the Rails 3 app:
      /lib/tasks
        rspec.rake

      /scripts
        autospec
        spec
      
      /spec
        rcov.opts
        spec.opts
        spec_helper.rb
