HepMCTraitsBase is a convenient base class for specializing the HepMCTraits class to deal with different flavours of HepMC in the HepMCConverter class.
The default version will work for the CLHEP implementation of HepMC. To use the HepMCConverter class for any flavour of HepMC you have to specialize the HepMCTraits class accordingly, possibly inheriting the functionality from the HepMCTraitsBase class and only overriding the functions and typedefs which are different. For the CLHEP flavour of HepMC you only need to do template<> struct HepMCTraits<HepMC::GenEvent>: public HepMCTraitsBase<HepMC::GenEvent,HepMC::GenParticle,HepMC::GenVertex, HepMC::Polarization> {};
somewhere inside the ThePEG namespace. The boolean template argument determines whether the HepMC implementation is specifying units or not.
