-<para>
-A GtkBuilder is an auxiliary object that reads textual descriptions
-of a user interface and instantiates the described objects. To pass a
-description to a GtkBuilder, call gtk_builder_add_from_file() or
-gtk_builder_add_from_string(). These functions can be called multiple
-times; the builder merges the content of all descriptions.
-</para>
-<para>
-A GtkBuilder holds a reference to all objects that it has constructed
-and drops these references when it is finalized. This finalization can
-cause the destruction of non-widget objects or widgets which are not
-contained in a toplevel window. For toplevel windows constructed by a
-builder, it is the responsibility of the user to call gtk_widget_destroy()
-to get rid of them and all the widgets they contain.
-</para>
-<para>
-The functions gtk_builder_get_object() and gtk_builder_get_objects()
-can be used to access the widgets in the interface by the names assigned
-to them inside the UI description. Toplevel windows returned by these
-functions will stay around until the user explicitly destroys them
-with gtk_widget_destroy(). Other widgets will either be part of a
-larger hierarchy constructed by the builder (in which case you should
-not have to worry about their lifecycle), or without a parent, in which
-case they have to be added to some container to make use of them.
-Non-widget objects need to be reffed with g_object_ref() to keep them
-beyond the lifespan of the builder.

-The function gtk_builder_connect_signals() and variants thereof can be
-used to connect handlers to the named signals in the description.

-<para>
-The toplevel element is <interface>.
-It optionally takes a "domain" attribute, which will make
-the builder look for translated strings using dgettext() in the
-domain specified. This can also be done by calling
-gtk_builder_set_translation_domain() on the builder.
-Objects are described by <object> elements, which can
-contain <property> elements to set properties, <signal>
-elements which connect signals to handlers, and <child>
-elements, which describe child objects (most often widgets
-inside a container, but also e.g. actions in an action group,
-or columns in a tree model). A <child> element contains
-an <object> element which describes the child object.
-The target toolkit version(s) are described by <requires>
-elements, the "lib" attribute specifies the widget library in
-question (currently the only supported value is "gtk+") and the "version"
-attribute specifies the target version in the form "<major>.<minor>".
-The builder will error out if the version requirements are not met.
-</para>
-<para>
-Typically, the specific kind of object represented by an
-<object> element is specified by the "class" attribute.
-If the type has not been loaded yet, GTK+ tries to find the
-<function>_get_type()</function> from the class name by applying
-heuristics. This works in most cases, but if necessary, it is
-possible to specify the name of the <function>_get_type()</function>
-explictly with the "type-func" attribute. As a special case,
-GtkBuilder allows to use an object that has been constructed
-by a #GtkUIManager in another part of the UI definition by
-specifying the id of the #GtkUIManager in the "constructor"
-attribute and the name of the object in the "id" attribute.
-</para>
-<para>
-Objects must be given a name with the "id" attribute, which
-allows the application to retrieve them from the builder with
-gtk_builder_get_object(). An id is also necessary to use the
-object as property value in other parts of the UI definition.
-</para>
-<note><para>Prior to 2.20, GtkBuilder was setting the "name"
-property of constructed widgets to the "id" attribute. In GTK+
-2.20 or newer, you have to use gtk_buildable_get_name() instead
-of gtk_widget_get_name() to obtain the "id", or set the "name"
-property in your UI definition.
-</para></note>
-<para>
-Setting properties of objects is pretty straightforward with
-the <property> element: the "name" attribute specifies
-the name of the property, and the content of the element
-specifies the value. If the "translatable" attribute is
-set to a true value, GTK+ uses gettext() (or dgettext() if
-the builder has a translation domain set) to find a translation
-for the value. This happens before the value is parsed, so
-it can be used for properties of any type, but it is probably
-most useful for string properties. It is also possible to
-specify a context to disambiguate short strings, and comments
-which may help the translators.
-</para>
-<para>
-GtkBuilder can parse textual representations for the most
-common property types: characters, strings, integers, floating-point
-numbers, booleans (strings like "TRUE", "t", "yes", "y", "1" are
-interpreted as %TRUE, strings like "FALSE, "f", "no", "n", "0" are
-interpreted as %FALSE), enumerations (can be specified by their
-name, nick or integer value), flags (can be specified by their name,
-nick, integer value, optionally combined with "|", e.g.
-"GTK_VISIBLE|GTK_REALIZED") and colors (in a format understood by
-gdk_color_parse()). Objects can be referred to by their name.
-Pixbufs can be specified as a filename of an image file to load.
-In general, GtkBuilder allows forward references to objects —
-an object doesn't have to constructed before it can be referred to.
-The exception to this rule is that an object has to be constructed
-before it can be used as the value of a construct-only property.
-</para>
-<para>
-Signal handlers are set up with the <signal> element.
-The "name" attribute specifies the name of the signal, and the
-"handler" attribute specifies the function to connect to the signal.
-By default, GTK+ tries to find the handler using g_module_symbol(),
-but this can be changed by passing a custom #GtkBuilderConnectFunc
-to gtk_builder_connect_signals_full(). The remaining attributes,
-"after", "swapped" and "object", have the same meaning as the
-corresponding parameters of the g_signal_connect_object() or
-g_signal_connect_data() functions. A "last_modification_time" attribute
-is also allowed, but it does not have a meaning to the builder.
-</para>
-<para>
-Sometimes it is necessary to refer to widgets which have implicitly
-been constructed by GTK+ as part of a composite widget, to set
-properties on them or to add further children (e.g. the @vbox
-of a #GtkDialog). This can be achieved by setting the "internal-child"
-propery of the <child> element to a true value. Note that
-GtkBuilder still requires an <object> element for the internal
-child, even if it has already been constructed.
-</para>
-<para>
-A number of widgets have different places where a child can be
-added (e.g. tabs vs. page content in notebooks). This can be reflected
-in a UI definition by specifying the "type" attribute on a <child>
-The possible values for the "type" attribute are described in
-the sections describing the widget-specific portions of UI definitions.
