The tests and examples in the tests directory show how to read, write, and use these types in your code.

Status

This project is in a beta stage -- feedback and use of it in production is encouraged, but expect changes until a stable version is released in some weeks.

Dependencies

Required:

• PODIO >= v00-15
• ROOT >= v6.22/06

Optional:

• Doxygen (to build code reference)
• HepMC (integration test)
• HepPDT (integration test)
