5## --------------------------------------------------------------------------- # 5# @DEPRECATED
6# subversion.eclass author: Akinori Hattori <hattya@gentoo.org> 6# This eclass has been superseded by git-2 eclass.
7# modified for git by Donnie Berkholz <spyderous@gentoo.org> 7# Please modify your ebuilds to use that one instead.

12# @BLURB: Fetching and unpacking of git repositories
13# @DESCRIPTION:
14# The git eclass provides functions to fetch, patch and bootstrap
15# software sources from git repositories and is based on the subversion eclass.
16# It is necessary to define at least the EGIT_REPO_URI variable.
17# @THANKS TO:
8# improved by Fernando J. Pereda <ferdy@gentoo.org> 18# Fernando J. Pereda <ferdy@gentoo.org>
9#
10# The git eclass is written to fetch the software sources from
11# git repositories like the subversion eclass.
12#
13#
14# Description:
15# If you use this eclass, the ${S} is ${WORKDIR}/${P}.
16# It is necessary to define the EGIT_REPO_URI variable at least.
