/***********************
* INTRODUCTION         *
***********************/

rnp_trace is a command line linux tool for tracing the of execution flows
of x86 linux applications easier.

rnp_trace
	1) forks a given executable
	2) loads the structure of ELFs in the forked process
	3) SINGLE_STEPs the forked process
	4) prints information about each instruction, including FUNCTION symbols
