license

The license of the program.

This string is displayed in a text view in a secondary dialog, therefore it is fine to use a long multi-paragraph text. Note that the text is only wrapped in the text view if the "wrap-license" property is set to true; otherwise the text itself must contain the intended linebreaks. When setting this property to a non-null value, the license_type property is set to gtk_license_custom as a side effect.
