+# This .inc file contains functionality for automatically splitting

+# package is also set up that has no files of its own, but contains
+# the names of all plugin packages in its RDEPENDS list.
+#
+# This is mainly used by the gstreamer1.0-plugins-* plugin set recipes,
+# but can be used in any recipe that produces GStreamer plugins.
+
+# Dynamically generate packages for all enabled plugins
