+                    When a recipe inherits the
+                    <filename>distro_features_check</filename> class, this
+                    variable identifies distribution features that would
+                    be in conflict should the recipe
+                    be built.
+                    In other words, if the
+                    <filename>CONFLICT_DISTRO_FEATURES</filename> variable
+                    lists a feature that also appears in
+                    <filename>DISTRO_FEATURES</filename> within the
+                    current configuration, an error occurs and the
+                    build stops.
