I wrote a small change to run.py so that you can now pass it e.g. - s 1-3,5,8-10 to run a list of specified scenarios (but not others) instead of just one at a time. This was very handy for what I was doing on Friday, especially with slower tests, and it seems unlikely I'd be the only person who might find it useful.-
