-// The interface used for implementing context-menu items. The following
-// instruction describe how to implement a context-menu item with this
-// interface.
-//
-// 1. Add command IDs for the context-menu items to 'chrome_command_ids.h'.
-//
-//   #define IDC_MY_COMMAND 99999
-//
-// 2. Add strings for the context-menu items to 'generated_sources.grd'.
-//
-//   <message name="IDS_MY_COMMAND" desc="...">
-//     My command
-//   </message>
-//
-// 3. Create a class that implements this interface. (It is a good idea to use
-// the RenderViewContextMenuDelegate interface to avoid accessing the
-// RenderViewContextMenu class directly.)
-//
-//  class MyMenuObserver : public RenderViewContextMenuObserver {
-//   public:
-//    MyMenuObserver(RenderViewContextMenuDelegate* d);
-//    ~MyMenuObserver();
-//
-//    virtual void InitMenu(const content::ContextMenuParams& params) OVERRIDE;
-//    virtual bool IsCommandIdSupported(int command_id) OVERRIDE;
-//    virtual bool IsCommandIdEnabled(int command_id) OVERRIDE;
-//    virtual void ExecuteCommand(int command_id) OVERRIDE;
-//
-//   private:
-//    RenderViewContextMenuDelgate* delegate_;
-//  }
-//
-//  void MyMenuObserver::InitMenu(const content::ContextMenuParams& params) {
-//    delegate_->AddMenuItem(IDC_MY_COMMAND,...);
-//  }
-//
-//  bool MyMenuObserver::IsCommandIdSupported(int command_id) {
-//    return command_id == IDC_MY_COMMAND;
-//  }
-//
-//  bool MyMenuObserver::IsCommandIdEnabled(int command_id) {
-//    DCHECK(command_id == IDC_MY_COMMAND);
-//    return true;
-//  }
-//
-//  void MyMenuObserver::ExecuteCommand(int command_id) {
-//    DCHECK(command_id == IDC_MY_COMMAND);
-//  }
-//
-// 4. Add this observer class to the RenderViewContextMenu class. (It is good
-// to use scoped_ptr<> so Chrome can create its instances only when it needs.)
-//
-//  class RenderViewContextMenu {
-//    ...
-//   private:
-//    scoped_ptr<MyMenuObserver> my_menu_observer_;
-//  };
-//
-// 5. Create its instance in InitMenu() and add it to the observer list of the
-// RenderViewContextMenu class.
-//
-//  void RenderViewContextMenu::InitMenu() {
-//    ...
-//    my_menu_observer_.reset(new MyMenuObserver(this));
-//    observers_.AddObserver(my_menu_observer_.get());
