/**
* SECTION:gtkaboutdialog
* @Short_description: Display information about an application
* @Title: GtkAboutDialog
*
* 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 `About` option from the `Help` menu.
* All parts of the dialog are optional.
*
* About dialogs 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 specify a person with an email address, use a string like
* "Edgar Allan Poe <edgar\@poe.com>". To specify a website with a title,
* use a string like "GTK+ team http://www.gtk.org".
*
* 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 `_("About %s")` on the dialog
* window (where \%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:
* |[<!-- language="C" -->
* gtk_show_about_dialog (NULL,
* "program-name", "ExampleCode",
* "logo", example_logo,
* "title" _("About ExampleCode"),
* NULL);
* ]|
*
* 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.
