But, alas, I do — I need to understand what the differences are between two JARs, and I haven’t looked into Java decompilers since JAD (goes to show… something).

P.S. The humility of the author in designating a pretty good product as a 0 version (a propos — this is silly) led me to dig further into this project and it is cool stuff. Look forward to digging some more.
