travis-avr-gcc

I wanted to get AVR-GCC running on Travis-CI. So I did.

This repository contains:

• A sample AVR codebase (demo.c / iocompat.h), lifted from AVR Libc
• A Makefile, lifted from mfile
• A .travis.yml to make it dance

Travis-CI checks that it builds, which is better than nothing. Suggestions of where to go from here:

1. Use travis-artifacts to export build artifacts.
2. Unit test the hardware-agnostic parts of your app using standard tools.
