Reveng is a disassembler for BeOS. As some other elf disassemblers, reveng uses objdump GNU tool to create a first disassembly of the file, and then creates a more a readable output file. So what's the difference with these disassemblers? Reveng (tries to) get as much references as possible by analysing some parts of the code, allowing it to guess what is behind a "push %eax" for example. It also gets all dynamic symbols references.
The aim of this tools is to find almost all functions, strings and other ressources references.
