| #GValue provides an abstract container structure which can be copied, |
| transformed and compared while holding a value of any (derived) type, which |
| is registered as a #GType with a #GTypeValueTable in its #GTypeInfo structure. |
| Parameter specifications for most value types can be created as |
| #GParamSpec derived instances, to implement e.g. #GObject properties which |
| operate on #GValue containers. |
