<para>
#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.
