setupEvtGen.sh

#!/bin/bash

# This script installs EvtGen with all external dependencies. The variable VERSION specifies the
# tag of EvtGen you want to use. The list of available tags can be found by either going to the url
# http://evtgen.hepforge.org/git?p=evtgen.git;a=tags
# or issuing the command (without the need to clone the git repository)
# git ls-remote --tags http://evtgen.hepforge.org/git/evtgen.git | cut -d '/' -f3
# Note that some earlier EvtGen versions will not be compatible with all external dependency
# versions given below, owing to C++ interface differences; see the specific tagged version of
# the EvtGen/README file for guidance.
# To obtain this script, use
# wget -O setupEvtGen.sh "http://evtgen.hepforge.org/git?p=evtgen.git;a=blob_plain;f=setupEvtGen.sh;hb=HEAD"

# Version or tag number. No extra spaces on this line!
VERSION=R01-07-00
# Pythia version number with no decimal points, e.g. 8230 corresponds to version 8.230. This
# follows the naming convention of Pythia install tar files. Again, no extra spaces allowed
