NAME="git"
VERSION=2.44.1
RELEASE=1
CATEGORY="Devel"
SUMMARY="Distributed version control system"
DESCRIPTION="Git is a free and open source distributed version control system
designed to handle everything from small to very large projects with speed and
efficiency. Git is easy to learn and has a tiny footprint with lightning fast
performance. It outclasses SCM tools like Subversion, CVS, Perforce, and
ClearCase with features like cheap local branching, convenient staging areas,
and multiple workflows."
