# 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 using either the 
# command "svn ls -v http://svn.cern.ch/guest/evtgen/tags" or by going to the url
# http://svn.cern.ch/guest/evtgen/tags in a web browser. 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

# Version or tag number. No extraneous spaces on this line!
VERSION=R01-06-00
