Event Record for Monte Carlo Generators

Official package sites : ·

The HepMC package is an object oriented event record written in C++ for High Energy Physics Monte Carlo Generators. Many extensions from HEPEVT, the Fortran HEP standard, are supported: the number of entries is unlimited, spin density matrices can be stored with each vertex, flow patterns (such as color) can be stored and traced, integers representing random number generator states can be stored, and an arbitrary number of event weights can be included. Particles and vertices are kept separate in a graph structure, physically similar to a physics event. The added information supports the modularisation of event generators. The package has been kept as simple as possible with minimal internal/external dependencies. Event information is accessed by means of iterators supplied with the package. Reference: M. Dobbs and J.B. Hansen, Comput. Phys. Commun. 134 (2001)41.

Build with cm instead of default mm for length units
Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
Install examples, usually source code
Build with GeV instead of default MeV for momentum units
Build static versions of dynamic libraries as well
Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)

proj/gentoo: Initial commit
This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H.
