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
