/**
* SECTION:gtkaboutdialog
* @Short_description: Display information about an application
* @Title: GtkAboutDialog
* @See_also: #GTK_STOCK_ABOUT
*
* The GtkAboutDialog offers a simple way to display information about
* a program like its logo, name, copyright, website and license. It is
* also possible to give credits to the authors, documenters, translators
* and artists who have worked on the program. An about dialog is typically
* opened when the user selects the <literal>About</literal> option from
* the <literal>Help</literal> menu. All parts of the dialog are optional.
*
* About dialog often contain links and email addresses. GtkAboutDialog
* displays these as clickable links. By default, it calls gtk_show_uri()
* when a user clicks one. The behaviour can be overridden with the
* #GtkAboutDialog::activate-link signal.
*
* To make constructing a GtkAboutDialog as convenient as possible, you can
* use the function gtk_show_about_dialog() which constructs and shows a dialog
* and keeps it around so that it can be shown again.
*
* Note that GTK+ sets a default title of <literal>_("About &percnt;s")</literal>
* on the dialog window (where &percnt;s is replaced by the name of the
* application, but in order to ensure proper translation of the title,
* applications should set the title property explicitly when constructing
* a GtkAboutDialog, as shown in the following example:
* <informalexample><programlisting>
* gtk_show_about_dialog (NULL,
* "program-name", "ExampleCode",
* "logo", example_logo,
* "title" _("About ExampleCode"),
* NULL);
* </programlisting></informalexample>
*
* It is also possible to show a #GtkAboutDialog like any other #GtkDialog,
* e.g. using gtk_dialog_run(). In this case, you might need to know that
* the 'Close' button returns the #GTK_RESPONSE_CANCEL response id.
