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

+# The bzr.eclass provides functions to fetch, unpack, patch, and
+# bootstrap sources from repositories of the Bazaar distributed version
+# control system. The eclass was originally derived from git.eclass.
+#
+# Note: Just set EBZR_REPO_URI to the URI of the branch and src_unpack()
+# of this eclass will export the branch to ${WORKDIR}/${P}.

+# @DEFAULT_UNSET
+# @DESCRIPTION:

+
+# @ECLASS-VARIABLE: EBZR_REPO_URI
+# @DEFAULT_UNSET
+# @REQUIRED
+# @DESCRIPTION:
+# The repository URI for the source package.
+#
+# Note: If the ebuild uses an sftp:// URI, then in EAPI 0 or 1 it must
+# make sure that dev-vcs/bzr was built with USE="sftp". In EAPI 2 or
+# later, the eclass will depend on dev-vcs/bzr[sftp].
+
+# @ECLASS-VARIABLE: EBZR_INITIAL_URI
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# The URI used for initial branching of the source repository. If this
+# variable is set, the initial branch will be cloned from the location
+# specified, followed by a pull from ${EBZR_REPO_URI}. This is intended
+# for special cases, e.g. when download from the original repository is
+# slow, but a fast mirror exists but may be out of date.
+#
+# Normally, this variable needs not be set.
+
+# @ECLASS-VARIABLE: EBZR_BOOTSTRAP
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# Bootstrap script or command like autogen.sh or etc.
+
+# @ECLASS-VARIABLE: EBZR_PATCHES
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# bzr.eclass can apply patches in bzr_bootstrap(). You can use regular
+# expressions in this variable like *.diff or *.patch and the like.
+# Note: These patches will be applied before EBZR_BOOTSTRAP is processed.
+#
+# Patches are searched both in ${PWD} and ${FILESDIR}. If not found in
+# either location, the installation dies.
+
+# @ECLASS-VARIABLE: EBZR_PROJECT
+# @DESCRIPTION:
+# The project name of your ebuild. Normally, the branch will be stored
+# in the ${EBZR_STORE_DIR}/${EBZR_PROJECT} directory.
+#
+# If EBZR_BRANCH is set (see below), then a shared repository will be
+# created in that directory, and the branch will be located in
+# ${EBZR_STORE_DIR}/${EBZR_PROJECT}/${EBZR_BRANCH}.
+: ${EBZR_PROJECT:=${PN}}
+
+# @ECLASS-VARIABLE: EBZR_BRANCH
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# The directory where to store the branch within a shared repository,
+# relative to ${EBZR_STORE_DIR}/${EBZR_PROJECT}.
+#
+# This variable should be set if there are several live ebuilds for
+# different branches of the same upstream project. The branches can
+# then share the same repository in EBZR_PROJECT, which will save both
+# data traffic volume and disk space.
+#
+# If there is only a live ebuild for one single branch, EBZR_BRANCH
+# needs not be set. In this case, the branch will be stored in a
+# stand-alone repository directly in EBZR_PROJECT.
+
+# @ECLASS-VARIABLE: EBZR_REVISION
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# Revision to fetch, defaults to the latest
+# (see http://bazaar-vcs.org/BzrRevisionSpec or bzr help revisionspec).
+
+# @ECLASS-VARIABLE: EBZR_OFFLINE
+# @DESCRIPTION:
+# Set this variable to a non-empty value to disable automatic updating
+# of a bzr source tree. This is intended to be set outside the ebuild
+# by users.
+: ${EBZR_OFFLINE=${EVCS_OFFLINE}}
+
+# @ECLASS-VARIABLE: EBZR_WORKDIR_CHECKOUT
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# If this variable is set to a non-empty value, EBZR_CHECKOUT_CMD will
+# be used instead of EBZR_EXPORT_CMD to copy the sources to WORKDIR.
+
