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. Johnson <> X-Thanks: Alec Warner <> - did the GSoC 2006 migration tests X-Thanks: Robin H. Johnson <> - infra guy, herding this project X-Thanks: Nguyen Thai Ngoc Duy <> - Former Gentoo developer, wrote Git features for the migration X-Thanks: Brian Harring <> - wrote much python to improve cvs2svn X-Thanks: Rich Freeman <> - validation scripts X-Thanks: Patrick Lauer <> - Gentoo dev, running new 2014 work in migration X-Thanks: Michał Górny <> - scripts, QA, nagging X-Thanks: All of other Gentoo developers - many ideas and lots of paint on the bikeshed

+ 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.
