  longDescription = ''
  grap takes patterns and binary files, uses a Casptone-based disassembler to obtain the control flow graphs from the binaries, then matches the patterns against them.
 
  Patterns are user-defined graphs with instruction conditions ("opcode is xor and arg1 is eax") and repetition conditions (3 identical instructions, basic blocks...).
