-/**
- * @defgroup Pager Pager
- *
- * The pager is an object that allows flipping (with animation) between 1 or
- * more “pages” of objects, much like a stack of windows within the window.
- *
- * Objects can be pushed or popped from the stack or deleted as normal.
- * Pushes and pops will animate (and a pop will delete the object once the
- * animation is finished). Any object in the pager can be promoted to the top
- * (from its current stacking position) as well. Objects are pushed to the
- * top with elm_pager_content_push() and when the top item is no longer
- * wanted, simply pop it with elm_pager_content_pop() and it will also be
- * deleted. Any object you wish to promote to the top that is already in the
- * pager, simply use elm_pager_content_promote(). If an object is no longer
- * needed and is not the top item, just delete it as normal. You can query
- * which objects are the top and bottom with elm_pager_content_bottom_get()
- * and elm_pager_content_top_get().
