-= Render Caching
-
-Cache render calls in Rails controllers.
-
-
-== Install
-
-First install the gem.
-
-  gem install ryanb-render-caching --source=http://gems.github.com
-
-Then specify it in your Rails config.
-
-	config.gem 'ryanb-render-caching', :lib => 'render_caching', :source => 'http://gems.github.com'
-
-Rails 2.1 or later required.
-
-
-== Usage
-
-This gem adds the render_with_cache method to all controllers. Call 
-this inside of an action to cache the view.
-
-	def show
-	  @user = User.find(params[:id])
-	  render_with_cache
-	end
-
-This will cache the full rendered contents into a key matching the URL 
-path (similar to action caching). You can change this key by simply 
-passing any parameter.
-
-	def show
-	  @user = User.find(params[:id])
-	  render_with_cache @user.cache_key
-	end
-
-Cache key is a method supplied by Rails. This includes the updated_at 
-time which will give you an auto-expiring cache when the user record is 
-updated.
-
-You can also supply a block to the render call which will only get 
-executed if there is no cache. Here is a good place to do any custom 
-render calls.
-
-	def show
-	  @user = User.find(params[:id])
-	  render_with_cache @user.cache_key do
-	    render :layout => false
-	  end
-	end
-
-
