New ramp kits can be added to the ramp-kits GitHub organization. To simplify
the update of the .travis.yml, you can execute directly the file
configure_travis.py:
python configure_travis.yml
It will generate a new travis.yml containing all the ramp-kits. It is also
possible to update the python version by edition configure_travis.yml. Once
that you generated a new .travis.yml, do not forget to commit the change.
