+/**
+ * Check GtkMM version
+ *
+ * This is adapted from the upstream Gtk+ macro for use with GtkMM
+ *
+ * @todo Perhaps this should be in its own header?  However, this is likely to
+ *       be used very frequently, so It would be annoying to have to add another
+ *	 header inclusion in many files
+ *
+ *
+ * @major: major version (e.g. 1 for version 1.2.5)
+ * @minor: minor version (e.g. 2 for version 1.2.5)
+ * @micro: micro version (e.g. 5 for version 1.2.5)
+ *
+ * Returns %TRUE if the version of the GTK+ header files
+ * is the same as or newer than the passed-in version.
+ *
+ * Returns: %TRUE if GTK+ headers are new enough
