+/**
+ * SECTION:gtkstatusbar
+ * @title: GtkStatusbar
+ * @short_description: Report messages of minor importance to the user
+ *
+ * A #GtkStatusbar is usually placed along the bottom of an application's
+ * main #GtkWindow. It may provide a regular commentary of the application's
+ * status (as is usually the case in a web browser, for example), or may be
+ * used to simply output a message when the status changes, (when an upload
+ * is complete in an FTP client, for example).
+ *
+ * Status bars in GTK+ maintain a stack of messages. The message at
+ * the top of the each bar's stack is the one that will currently be displayed.
+ *
+ * Any messages added to a statusbar's stack must specify a
+ * <emphasis>context id</emphasis> that is used to uniquely identify
+ * the source of a message. This context id can be generated by
+ * gtk_statusbar_get_context_id(), given a message and the statusbar that
+ * it will be added to. Note that messages are stored in a stack, and when
+ * choosing which message to display, the stack structure is adhered to,
+ * regardless of the context identifier of a message.
+ *
+ * One could say that a statusbar maintains one stack of messages for
+ * display purposes, but allows multiple message producers to maintain
+ * sub-stacks of the messages they produced (via context ids).
+ *
+ * Status bars are created using gtk_statusbar_new().
+ *
+ * Messages are added to the bar's stack with gtk_statusbar_push().
+ *
+ * The message at the top of the stack can be removed using
+ * gtk_statusbar_pop(). A message can be removed from anywhere in the
+ * stack if its message id was recorded at the time it was added. This
+ * is done using gtk_statusbar_remove().
