9# @BLURB: Fetching and unpacking of git repositories
10# @DESCRIPTION:
11# The git eclass provides functions to fetch, patch and bootstrap
12# software sources from git repositories and is based on the subversion eclass.
13# It is necessary to define at least the EGIT_REPO_URI variable.
14# @THANKS TO:
8# improved by Fernando J. Pereda <ferdy@gentoo.org> 15# 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.
