       # ==== Examples
+      # Because it relies on +url_for+, +link_to+ supports both older-style controller/action/id arguments
+      # and newer RESTful routes.  Current Rails style favors RESTful routes whenever possible, so base
+      # your application on resources and use
+      #
+      #   link_to "Profile", profile_path(@profile)
+      #   # => <a href="/profiles/1">Profile</a>
+      #
+      # or the even pithier
+      #
+      #   link_to "Profile", @profile
+      #   # => <a href="/profiles/1">Profile</a>
+      #
+      # in place of the older more verbose, non-resource-oriented
+      #
+      #   link_to "Profile", :controller => "profiles", :action => "show", :id => @profile
+      #   # => <a href="/profiles/show/1">Profile</a>
+      # 
+      # Similarly, 
+      #
+      #   link_to "Profiles", profiles_path
+      #   # => <a href="/profiles">Profiles</a>
+      #
+      # is better than
+      #
+      #   link_to "Profiles", :controller => "profiles"
+      #   # => <a href="/profiles">Profiles</a>
+      #
+      # Classes and ids for CSS are easy to produce:
+      #
+      #   link_to "Articles", articles_path, :id => "news", :class => "article"
+      #   # => <a href="/articles" class="article" id="news">Articles</a>
+      #
+      # Be careful when using the older argument style, as an extra literal hash is needed:
+      #
+      #   link_to "Articles", { :controller => "articles" }, :id => "news", :class => "article"
+      #   # => <a href="/articles" class="article" id="news">Articles</a>
+      #
+      # Leaving the hash off gives the wrong link:
+      #
+      #   link_to "WRONG!", :controller => "articles", :id => "news", :class => "article"
+      #   # => <a href="/articles/index/news?class=article">WRONG!</a>
+      #
+      # +link_to+ can also produce links with anchors or query strings:
+      #
+      #   link_to "Comment wall", profile_path(@profile, :anchor => "wall")
+      #   # => <a href="/profiles/1#wall">Comment wall</a>
+      #
+      #   link_to "Ruby on Rails search", :controller => "searches", :query => "ruby on rails"
+      #   # => <a href="/searches?query=ruby+on+rails">Ruby on Rails search</a>
+      #
+      #   link_to "Nonsense search", searches_path(:foo => "bar", :baz => "quux")

+      #
