+    longDescription = ''
+      This library can be used to easily access XML data of
+      the iso-codes package. It will provide an abstraction
+      layer to handle both the version 3 and the upcoming
+      version 4 of iso-codes. Moreover, all available
+      translations can be used as well.
+
+      This library makes use of the GObject introspection
+      features, so that it is accessible from a variety of
+      programming languages, for example C, Vala, Ruby,
+      Python, Perl, Lua, JavaScript, PHP and many more.
