7# modified for git by Donnie Berkholz <spyderous@gentoo.org> 7# Tomas Chvatal <scarabeus@gentoo.org>
8# improved by Fernando J. Pereda <ferdy@gentoo.org> 8# Donnie Berkholz <dberkholz@gentoo.org>
9# 9# @BLURB: This eclass provides functions for fetch and unpack git repositories
10# The git eclass is written to fetch the software sources from 10# @DESCRIPTION:
11# git repositories like the subversion eclass. 11# The eclass is based on subversion eclass.
12#
13#
14# Description:
15# If you use this eclass, the ${S} is ${WORKDIR}/${P}. 12# If you use this eclass, the ${S} is ${WORKDIR}/${P}.
16# It is necessary to define the EGIT_REPO_URI variable at least. 13# It is necessary to define the EGIT_REPO_URI variable at least.
