+ * @short_description: A container structure to maintain an array of
+ * generic values
+ * @see_also: #GValue, #GParamSpecValueArray, g_param_spec_value_array()
+ * @title: Value arrays
+ *
+ * The prime purpose of a #GValueArray is for it to be used as an
+ * object property that holds an array of values. A #GValueArray wraps
+ * an array of #GValue elements in order for it to be used as a boxed
+ * type through %G_TYPE_VALUE_ARRAY.
+ *
+ * #GValueArray is deprecated in favour of #GArray since GLib 2.32. It
+ * is possible to create a #GArray that behaves like a #GValueArray by
+ * using the size of #GValue as the element size, and by setting
+ * g_value_unset() as the clear function using g_array_set_clear_func(),
+ * for instance, the following code:
+ *
+ * |[<!-- language="C" -->
+ * GValueArray *array = g_value_array_new (10);
+ * ]|
+ *
+ * can be replaced by:
+ *
+ * |[<!-- language="C" -->
+ * GArray *array = g_array_sized_new (FALSE, TRUE, sizeof (GValue), 10);
+ * g_array_set_clear_func (array, (GDestroyNotify) g_value_unset);
