As I said, jtreg is (just) a relatively simple n-way diff program for  
comparing sets of jtreg results.

By itself, it does not provide any infrastructure for maintaining  
those results for wider later
comparison. However, if you were to organize your results into a  
directory tree such as
then it should be reasonably easy to write scripts to the platform- 
wide or date-based
comparison runs.  I don't think I mentioned yesterday, jtdiff has an  
Ant task too,
so maybe you can do the processing you need inside Ant. You should  
also be able to
invoke jtdiff directly from other Java code too.
