+/**
+ * SECTION:gtkscale
+ * @Short_description: A slider widget for selecting a value from a range
+ * @Title: GtkScale
+ *
+ * A GtkScale is a slider control used to select a numeric value.
+ * To use it, you'll probably want to investigate the methods on
+ * its base class, #GtkRange, in addition to the methods for GtkScale itself.
+ * To set the value of a scale, you would normally use gtk_range_set_value().
+ * To detect changes to the value, you would normally use the
+ * #GtkRange::value-changed signal.
+ *
+ * Note that using the same upper and lower bounds for the #GtkScale (through
+ * the #GtkRange methods) will hide the slider itself. This is useful for
+ * applications that want to show an undeterminate value on the scale, without
+ * changing the layout of the application (such as movie or music players).
+ *
+ * GtkScale as GtkBuildable
+ * GtkScale supports a custom <marks> element, which
+ * can contain multiple <mark> elements. The "value" and "position"
+ * attributes have the same meaning as gtk_scale_add_mark() parameters of the
+ * same name. If the element is not empty, its content is taken as the markup
+ * to show at the mark. It can be translated with the usual "translatable and
+ * "context" attributes.
