DESCRIPTION="Lund Monte Carlo high-energy physics event generator"
HOMEPAGE="http://projects.hepforge.org/pythia6/"

# pythia6 from root is needed for some files to interface pythia6 with root.
# To produce a split version on mirror do, replace the 6.4.x by the current version
# svn export http://svn.hepforge.org/pythia6/tags/v_6_4_x/ pythia-6.4.x
# tar cjf pythia-6.4.x.tar.bz2
