Detailed Description

This a wrapper around HepMC::Pythia8ToHepMC in the Pythia8 namespace that simplify the most common use cases. It stores the current GenEvent and output stream internally to avoid cluttering of user code. This class is also defined in HepMC3.h with the same signatures, and the user can therefore switch between HepMC version 2 and 3, by simply changing the include file.
