For information Parabola is *trying to* start to works on a fully free
port for ARM.

Like every type of project we need more hackers!

So you are all welcome to join.

The goal is to make ASAP a fully free ARM port and next a fully free ROS
that will works with it.

That mean, fully free solution for the internet of things and robotics.
