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 <robbat2@gentoo.org> X-Thanks: Alec Warner <antarus@gentoo.org> - did the GSoC 2006 migration tests X-Thanks: Robin H. Johnson <robbat2@gentoo.org> - infra guy, herding this project X-Thanks: Nguyen Thai Ngoc Duy <pclouds@gentoo.org> - Former Gentoo developer, wrote Git features for the migration X-Thanks: Brian Harring <ferringb@gentoo.org> - wrote much python to improve cvs2svn X-Thanks: Rich Freeman <rich0@gentoo.org> - validation scripts X-Thanks: Patrick Lauer <patrick@gentoo.org> - Gentoo dev, running new 2014 work in migration X-Thanks: Michał Górny <mgorny@gentoo.org> - scripts, QA, nagging X-Thanks: All of other Gentoo developers - many ideas and lots of paint on the bikeshed

+# Other than the variables normally set by portage, this function's behavior

+# SNAPSHOT
+# If set, this variable signals that we should be using a snapshot of

+# the ebuild has a _pre suffix, this variable is ignored and the
+# prerelease tarball is used instead.
+#
+# BRANCH_UPDATE
+# If set, this variable signals that we should be using the main
+# release tarball (determined by ebuild version) and applying a
+# CVS branch update patch against it. The location of this branch
+# update patch is assumed to be in ${GENTOO_TOOLCHAIN_BASE_URI}.
+# Just like with SNAPSHOT, this variable is ignored if the ebuild
+# has a _pre suffix.
+#
+# PATCH_VER
+# PATCH_GCC_VER
+# This should be set to the version of the gentoo patch tarball.
+# The resulting filename of this tarball will be:
+# gcc-${PATCH_GCC_VER:-${GCC_RELEASE_VER}}-patches-${PATCH_VER}.tar.bz2
+#
+# PIE_VER
+# PIE_GCC_VER
+# These variables control patching in various updates for the logic
+# controlling Position Independant Executables. PIE_VER is expected
+# to be the version of this patch, and PIE_GCC_VER the gcc version of
+# the patch:
+# An example:
+# PIE_VER="8.7.6.5"
+# PIE_GCC_VER="3.4.0"
+# The resulting filename of this tarball will be:
+# gcc-${PIE_GCC_VER:-${GCC_RELEASE_VER}}-piepatches-v${PIE_VER}.tar.bz2
+#
+# SPECS_VER
+# SPECS_GCC_VER
+# This is for the minispecs files included in the hardened gcc-4.x
+# The specs files for hardenedno*, vanilla and for building the "specs" file.
+# SPECS_VER is expected to be the version of this patch, SPECS_GCC_VER
+# the gcc version of the patch.
+# An example:
+# SPECS_VER="8.7.6.5"
+# SPECS_GCC_VER="3.4.0"
+# The resulting filename of this tarball will be:
+# gcc-${SPECS_GCC_VER:-${GCC_RELEASE_VER}}-specs-${SPECS_VER}.tar.bz2
+#
+# HTB_VER

+# These variables control whether or not an ebuild supports Herman
