sci-physics@gentoo.org Gentoo Physics Project Herwig++ is a completely new event generator, written in C++. It is built on the experience gained with the well-known event generator HERWIG. The aim is to provide a multi purpose event generator with similar or improved capabilities (like angular ordered parton evolution and the cluster hadronization model). Build Herwig++ using the C++11 standard. Experimental feature, not for production use. Adds support for sci-physics/fastjet
