From 56bd759df1d0c750a065b8c845e93d5dfa6b549d Mon Sep 17 00:00:00 2001 From: "Robin H. Johnson" Date: Sat, 8 Aug 2015 13:49:04 -0700 Subject: proj/gentoo: Initial commit MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
