%description
It is built based on the experience gained with both the HERWIG 6 and 
Herwig++ 2 event generators. Continuing the Herwig++ 2 development, 
Herwig 7.0 (Herwig++ 3.0) replaces any prior HERWIG or Herwig++ versions.
Herwig provides significantly improved and extended physics capabilities 
when compared to both its predecessors, HERWIG 6 and Herwig++ 2, while 
keeping the key model motivations such as 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.
