* @short_description: introduction to the GVariant type system
* @see_also: #GVariantType, #GVariant
*
* This section introduces the GVariant type system. It is based, in
- * large part, on the DBus type system, with two major changes and some minor
+ * large part, on the D-Bus type system, with two major changes and some minor
* lifting of restrictions. The <ulink
* url='http://dbus.freedesktop.org/doc/dbus-specification.html'>DBus
* specification</ulink>, therefore, provides a significant amount of
* information that is useful when working with GVariant.
*
- * The first major change with respect to the DBus type system is the
+ * The first major change with respect to the D-Bus type system is the
* introduction of maybe (or "nullable") types. Any type in GVariant can be
* converted to a maybe type, in which case, "nothing" (or "null") becomes a
* valid value. Maybe types have been added by introducing the
*
* The second major change is that the GVariant type system supports the
* concept of "indefinite types" -- types that are less specific than
- * the normal types found in DBus. For example, it is possible to speak
- * of "an array of any type" in GVariant, where the DBus type system
+ * the normal types found in D-Bus. For example, it is possible to speak
+ * of "an array of any type" in GVariant, where the D-Bus type system
* would require you to speak of "an array of integers" or "an array of
* strings". Indefinite types have been added by introducing the
* characters "<literal>*</literal>", "<literal>?</literal>" and
* types are lifted along with the restriction that dictionary entries
* may only appear nested inside of arrays.
*
- * Just as in DBus, GVariant types are described with strings ("type
+ * Just as in D-Bus, GVariant types are described with strings ("type
* strings"). Subject to the differences mentioned above, these strings
- * are of the same form as those found in DBus. Note, however: DBus
+ * are of the same form as those found in DBus. Note, however: D-Bus
* always works in terms of messages and therefore individual type
* strings appear nowhere in its interface. Instead, "signatures"
* are a concatenation of the strings of the type of each argument in a
* message. GVariant deals with single values directly so GVariant type
* strings always describe the type of exactly one value. This means
- * that a DBus signature string is generally not a valid GVariant type
+ * that a D-Bus signature string is generally not a valid GVariant type
* string -- except in the case that it is the signature of a message
* containing exactly one argument.
*
* indefinite type as its type, but values can exist that have types
* that are subtypes of indefinite types. That is to say,
* g_variant_get_type() will never return an indefinite type, but
- * calling g_variant_is_a() with an indefinite type may return %TRUE.
- * For example, you can not have a value that represents "an array of no
- * particular type", but you can have an "array of integers" which
- * certainly matches the type of "an array of no particular type", since
- * "array of integers" is a subtype of "array of no particular type".
+ * calling g_variant_is_of_type() with an indefinite type may return
+ * %TRUE. For example, you cannot have a value that represents "an
+ * array of no particular type", but you can have an "array of integers"
+ * which certainly matches the type of "an array of no particular type",
+ * since "array of integers" is a subtype of "array of no particular
+ * type".
*
* This is similar to how instances of abstract classes may not
* directly exist in other type systems, but instances of their
