Hi guys, We are planning to add git.eclass as presented in bug #132383 (as attachment 96300). I also attach it here in case someone wants to comment parts of it.
Please raise your concerns if you have any. - ferdy -- Fernando J. Pereda GarcimartÃn Gentoo Developer (Alpha,net-mail,mutt,git) 20BB BDC3 761A 4781 E6ED ED0B 0A48 5B0C 60BD 28D4

#
# The git eclass is written to fetch the software sources from
# git repositories like the subversion eclass.
#
#
# Description:
# If you use this eclass, the ${S} is ${WORKDIR}/${P}.
# It is necessary to define the EGIT_REPO_URI variable at least.
#

EGIT="git.eclass"
EXPORT_FUNCTIONS src_unpack
HOMEPAGE="http://git.or.cz/";
DESCRIPTION="Based on the ${ECLASS} eclass"
## -- add git in DEPEND
#
DEPEND=">=dev-util/git-1.4.0"
## -- EGIT_STORE_DIR: git sources store directory
#
EGIT_STORE_DIR="${PORTAGE_ACTUAL_DISTDIR-${DISTDIR}}/git-src"
## -- EGIT_FETCH_CMD: git clone command
#
EGIT_FETCH_CMD="git clone --bare"
## -- EGIT_UPDATE_CMD: git fetch command
#
EGIT_UPDATE_CMD="git fetch -f -u"
## -- EGIT_DIFFSTAT_CMD: Command to get diffstat output
#
EGIT_DIFFSTAT_CMD="git diff --stat"
## -- EGIT_OPTIONS:
#
# the options passed to clone and fetch
#
: ${EGIT_OPTIONS:=}
## -- EGIT_REPO_URI: repository uri
#
# e.g. http://foo, git://bar
#
# supported protocols:
# http://
# https://
# git://
# git+ssh://
# rsync://
# ssh://
#
: ${EGIT_REPO_URI:=}
## -- EGIT_PROJECT: project name of your ebuild
#
# git eclass will check out the git repository like:
#
# ${EGIT_STORE_DIR}/${EGIT_PROJECT}/${EGIT_REPO_URI##*/}
#
# so if you define EGIT_REPO_URI as http://git.collab.net/repo/git or
# http://git.collab.net/repo/git. and PN is subversion-git.
# it will check out like:
#
# ${EGIT_STORE_DIR}/subversion
#
# default: ${PN/-git}.
#
: ${EGIT_PROJECT:=${PN/-git}}
## -- EGIT_BOOTSTRAP:
#
# bootstrap script or command like autogen.sh or etc..
#
: ${EGIT_BOOTSTRAP:=}
## -- EGIT_PATCHES:
#
# git eclass can apply pathces in git_bootstrap().
# you can use regexp in this valiable like *.diff or *.patch or etc.
# NOTE: this patches will apply before eval EGIT_BOOTSTRAP.
#
# the process of applying the patch is:
# 1. just epatch it, if the patch exists in the path.
# 2. scan it under FILESDIR and epatch it, if the patch exists in FILESDIR.
# 3. die.
#
: ${EGIT_PATCHES:=}
## -- EGIT_BRANCH:
#
# git eclass can fetch any branch in git_fetch().
# Defaults to 'master'
#
: ${EGIT_BRANCH:=master}
## -- EGIT_TREE:
#
# git eclass can checkout any tree.
# Defaults to EGIT_BRANCH.
#
: ${EGIT_TREE:=${EGIT_BRANCH}}
## - EGIT_REPACK:
#
# git eclass will repack objects to save disk space. However this can take a
# long time with VERY big repositories. If this is your case set:
# EGIT_REPACK=false
#
: ${EGIT_REPACK:=false}
## - EGIT_PRUNE:
#
# git eclass can prune the local clone. This is useful if upstream rewinds and
# rebases branches too often. If you don't want this to happen, set:
# EGIT_PRUNE=false
#
: ${EGIT_PRUNE:=false}
