+=item affects_distribution_tags
+
+List of tags which restrict the buggy state to a set of distributions.
+
+The set of distributions that are buggy is the intersection of the set
+of distributions that would be buggy without reference to these tags
+and the set of these tags that are distributions which are set on a
+bug.
+
+Setting this to [] will remove this feature.
