<h2>Alternatives</h2>
There are quite a few Java class file shrinkers, optimizers, obfuscators, and
preverifiers out there. Users of <b>ProGuard</b> tell me it easily compares
with the best of them. However, you may want to check that out yourself.
<p>
This is a list of the programs of which I'm aware. Obviously, I've never
personally tested all of them. Many programs, even commercial ones, have been
abandoned. Please drop me a note if you know of any other shrinkers,
optimizers, obfuscators, or preverifiers, or if some information provided
below is incorrect.
