python-ptrace is a debugger using ptrace written in Python.
Fearures:
 o High level Python object API : PtraceDebugger and PtraceProcess
 o Able to control multiple processes: catch fork events on Linux
 o Read/write bytes to arbitrary address: take care of memory alignment
   and split bytes to cpu word
 o Execution step by step using ptrace_singlestep()
   or hardware interruption 3
 o Dump registers, memory mappings, stack, etc.
 o Syscall tracer and parser (strace.py command)
 o Can use distorm disassembler (if available)
