Comment (by LeadAssimilator):

 What in my answer is difficult to parse exactly?

 3.4.2 success
 4.0.0 fail
 4.0.1 fail
 4.0.2 fail
 4.1.0 fail
 4.1.1 fail
 4.1.3 fail
 4.2.0 fail
 4.2.1 fail
 4.2.2 fail
 master/head fail

 The commandlines are already in both the description and the report files.
 And the output is there as well, albeit intermixed with the stuff that
 -report adds.  I'm not sure why you encourage including them if you are
 just going to ignore them...

 The output w/o -report is this for the one sample I uploaded (I don't yet
 have an input sample to upload for the "invalid band type" error yet):

 And this would be a hell of a lot easier and less confusing if we could
 have the edit description grant for our own trac tickets...especially
 since I have to upload samples separately causing the names to mismatch
 what I originally specified.
