(Hopper is a binary disassembler and decompiler for 32bits and
64bits executables. This tool will let you disassemble any binary
you want, and provide you all the information about its content,
like imported symbols, or the control flow graph! Hopper can
retrieve procedural information about the disassembled code like
the stack variables, and lets you name all the objects you want.
Hopper is now able to transform the assembly language into a
pseudo-code that is easier to understand! You can even use its
internal Python scripting engine to analyze binaries the way you
want (this feature works only with Lion)!)
