JEST will be the Java bytecode engineering Swiss-Army Jackhammer.
It will include a disassembler, class browser, obfuscator, optimizer, class editor, and bytecode debugger, and have an intuitive GUI.
A collection of ACS tools. It will have an ACS disassembler, because I intend to get a method of decompiling as quickly as possible. After that, there will be: compiler, decompiler, linker and translator, etc...
