28 * AnjutaDock provides an alternative to the traditional menu and toolbar based
29 * methodologies used by most GNOME programs. Instead, it focuses on tasks, or
30 * related sets of tasks. Each pane in the dock corresponds to a different set
31 * of related tasks.
32 *
33 * Optionally, you can also associate an #AnjutaCommandBar with an AnjutaDock to
34 * provide contextually appropriate sets of commands depending on the currently
35 * visible pane
