 * #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.
 *
 * Parameter names need to start with a letter (a-z or A-Z). Subsequent
 * characters can be letters, numbers or a '-'.
 * All other characters are replaced by a '-' during construction.
