Definitely 2.2.1!

It should be automatically downloaded and installed by the bootstrap --
was it not?

We don't install AGILe anymore, since the world mostly moved on from the
Fortran MC generators and the LCG directory structure that contained
them has also changed. We might bring AGILe back to life at some point,
but there's not a lot of demand (i.e. no-one has asked!)

If you want a generator code to try out, I think Pythia8 is the easiest
to install and use. Sherpa and Herwig++ are also quite easy to install
-- not *quite* as easy -- but they are more configurable, which means a
bit more complexity.

Ah, I see: we should update that example to not mention agile-runmc...

Hopefully the bootstrap will download everything you need, other than a
copy of Pythia8 or whichever generator you prefer. I find the Sacrifice
interface a nice way to steer Pythia8 -- we have a link to that from the
Rivet web page, IIRC.

Cheers,
Andy
