+This is the vapi for GEGL. The GEGL API coverrage is not complete due
+to API stability and maturity issues.
+
+Currently, it is not yet possible to write GEGL Operation from
+Vala. You can build a pipeline and process it.
+
+See http://live.gnome.org/Vala for more details about Vala programming
+language.
