This one is more recent, though the  format specs are basically the same in the CrashUtils docs. I condensed the 4 swapping node formats  in the CrashUtils docs  to 2 formats with optional extension (i.e. an optional "follow-up node"). So the "format A" specified in those docs corresponds to format A without the extension, as listed above, "format B" to format A with the extension, "format C" to format B with the extension, and "format D " to format B without the extension.
