 Description:
     The resource generator creates an empty model, controller, and functional
-    suitable for inclusion in a REST-like, resource-oriented application.

     The generator takes the name of the model as its first argument. This
     model name is then pluralized to get the controller name. So "resource
-    post" will generate a Post model and a PostsController and will be 
+    post" will generate a Post model and a PostsController and will be
     intended for URLs like /posts and /posts/45.

     As additional parameters, the generator will take attribute pairs
     described by name and type. These attributes will be used to
-    prepopulate the migration to create the table for the model. For

     published:boolean" will give you a Post model with those four attributes.

     You don't have to think up all attributes up front, but it's a good
     idea of adding just the baseline of what's needed to start really
     working with the resource.

-    The generator also adds an appropriate map.resources declaration to 
-    your config/routes.rb file, hooking up the rules that'll point URLs to

     Unlike the scaffold generator, the resource generator does not
     create views or add any methods to the generated controller.
