# PATCH-FIX-OPENSUSE Herwig-disable-repo-install.patch badshah400@gmail.com -- Disable post-install hooks intended to set up the Herwig repo, this doesn't work inside the build script because of missing LHAPDF data that needs to be installed by the user; the install-hook doesn't serve any purpose while building the rpm and users can easily set this up on their own

%description
Herwig is a multi-purpose particle physics event generator.
Herwig 7.0 (Herwig++ 3.0) replaces any prior HERWIG or Herwig++ versions.

Herwig features coherent parton showers (including angular-ordered
and dipole-based evolution), the cluster hadronization model, an
eikonal multiple-interaction model, highly flexible BSM capabilities
and improved perturbative input using next-to-leading order QCD.

Herwig is based on ThePEG.
