| * contains the content of one URI. The URI and name of the frame can |
| * be retrieved, the load status and progress can be observed using the |

| * A #WebKitWebFrame can have any number of children and one child can |
| * be found by using #webkit_web_frame_find_frame. |
| * |
| * <informalexample><programlisting> |
