We certainly don't want spurious output, so that means we need to get creative.

We have the last version before the license changed. We haven't been cleared to use the file under the newer license. We have so far made the interpretation that we should not modify the file we imported directly, which is why we have a wrapper script. The wrapper script just has to do what's necessary to compensate for the older version of the real script.
