-// compression_generate.go is meant to run with go generate. It will use
-// go/{importer,types} to track down all the RR struct types. Then for each type
-// it will look to see if there are (compressible) names, if so it will add that
-// type to compressionLenHelperType and comressionLenSearchType which "fake" the
-// compression so that Len() is fast.
