Android: How to add menu items to a ActionBarSherlock MapActivity
===

I am using [ActionBarSherlock][1] with [ActionBarSherlock-Plugin-Maps][2] in my project. I would like to add menu items to the actionbar of my `MapActivity` as it is possible for a standard activity that inherits from `SherlockActivity`. The following code sample shows how to create an icon.

    public class CustomSherlockActivity extends SherlockActivity {
        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            menu.add("Save")
                .setIcon(R.drawable.ic_compose)
                .setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
            return true;
        }

However, I can **not** use the same method in my `MapActivity` that extends `SherlockMapActivity`. The method `SherlockMapActivity#onCreateOptionsMenu` is defined `final`. Here is the [source code of `SherlockMapActivity`][3]. How then, am I supposed to add actions to the actionbar?
