I was trying to get the "Hello World" program up and running with an Aruino Mega board.

I finished the entire thing but got stuck on compiling the actual example code.

http://www.ros.org/wiki/avr_bridge/Tutorials/Hello%20World#main.cpp

It has an include which is not in the downloadable eclipse project:

#include "avrRos/Ros.h" //main avrRos library
#include "avrRos/String.h" //std_msg/String library

I couldn't find the String.h file on the git hub either:
