                  // This is weird, so bear with me. The best thing we can
                  // have is something straightforward and in our own
                  // language. If it has a description, then it is
                  // probably used for something other than an actual
                  // comment. If that doesn't work, we'd still rather have
                  // something in our language than something in another.
                  // After that all we have left are things in other
                  // languages, so we'd rather have one with actual
                  // content, so we try to get one with no description
                  // first.
