[Rivet] agile interface with Alpgen

[treccani at ugr.es]

Dear Rivet & Agile developers,
I would like to interface Rivet with alpgen+Pythia and alpgen+Herwig for
MonteCarlo validation and tuning.
I have followed your suggestion installing Agile interface, but I can't
find the way to install alpgen and make it visible to Agile.
can you please give more hints?
p.s. I have read also about rivetgun without finding any further
reference: has it been superseded by Agile?
I work on fresh new Fedora 13.

Cheers, Michele Treccani
