Yep, something like this in its simplest form.
But I'd like to make it a little more generic and powerful, for
example allowing for some action before or after the main call, for
the user to express the name of the experiment, for actions before or
after the whole script, etc...

The question wasn't how to do it, but what would be the best way to do
it, if you see what I mean. I've got a few ideas and I am not sure
what will work because some (like a DSL) I've never done before and
others (like a Yaml file) may not be enough.
