+    # Returns an `li` element with an 'active' class if the supplied
+    # controller(s) and/or action(s) are currently active. The content of the
+    # element is the value passed to the block.
+    #
+    # options - The options hash used to determine if the element is "active" (default: {})
+    #           :controller   - One or more controller names to check (optional).
+    #           :action       - One or more action names to check (optional).
+    #           :path         - A shorthand path, such as 'dashboard#index', to check (optional).
+    #           :html_options - Extra options to be passed to the list element (optional).
+    # block   - An optional block that will become the contents of the returned
+    #           `li` element.
+    #
+    # When both :controller and :action are specified, BOTH must match in order
+    # to be marked as active. When only one is given, either can match.
+    #
+    # Examples
+    #
+    #   # Assuming we're on TreeController#show
+    #
+    #   # Controller matches, but action doesn't
+    #   nav_link(controller: [:tree, :refs], action: :edit) { "Hello" }
+    #   # => '<li>Hello</li>'
+    #
+    #   # Controller matches
+    #   nav_link(controller: [:tree, :refs]) { "Hello" }
+    #   # => '<li class="active">Hello</li>'
+    #
+    #   # Shorthand path
+    #   nav_link(path: 'tree#show') { "Hello" }

+    #   # Supplying custom options for the list element
