Minimal version

[tbarbette]

We need a way to specify a script needs a specific version of NPF

In the %require section it will only start at the same time than tests.

Maybe a new section, a "%globalrequire" that runs directly before any test, or a config option like npf_min_ver=1.1.0

This works in NPF v2 (only a branch for now):

%require
npfv=${NPF_VERSION}
function version { echo "$@" | awk -F. '{ printf("%d%03d%03d%03d\n", $1,$2,$3,$4); }'; }
if [ -z "$npfv" $(version $npfv) -lt $(version "2.0.1") ]; then
    echo "You must update NPF (current version $npfv)! v2 is only available through NPF's github branch. Set the path in launch.sh."
    exit 1
fi

It should be documented so I leave this open.
