CLHep 2.06.08

A set of HEP-specific foundation and utility classes
CLHep is intended to be a set of HEP-specific foundation and utility classes such as random generators, physics vectors, geometry, and linear algebra.

Some of the files in the examples directory are aimed at showing you how to use HepMC with Pythia. Currently it links to Pythia6.1.

Some platforms require the initialization of pythia PYDATA block data as external this is accomplished by the initpydata() call. If you get pythia initialization errors try commenting in/out the initpydata() call in the MyPythia examples.

Note the Pythia wrappers are not intended to be part of the HepMC package, they are only provided to make the examples run.

What's New in This Release:
  • GenEvent has a new method, define_units() which can be used when the units in this event do not match the default units. Define_units() does not convert momenta or lenght.
  • In addition, fix a bug so that IO_GenEvent::use_input_units() is properly consulted for all input cases.
  • fix a typo in cmake/Modules/HepMCVariables.cmake
  • add more testing of the Units functionality
