9# you should currently poke with updates Tomas Chvatal <scarabeus@gentoo.org> 9# @BLURB: This eclass provides functions for fetch and unpack git repositories
10# 10# @DESCRIPTION:
11# The git eclass is written to fetch the software sources from 11# The eclass is based on subversion eclass.
12# git repositories like the subversion eclass.

15# Description:
16# If you use this eclass, the ${S} is ${WORKDIR}/${P}. 12# If you use this eclass, the ${S} is ${WORKDIR}/${P}.
17# 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.
