Subject: [PATCH v2 03/14] commit-graph: create git-commit-graph builtin
Date: Tue, 30 Jan 2018 16:39:32 -0500	[thread overview]
Message-ID: <1517348383-112294-4-git-send-email-dstolee@microsoft.com> (raw)
In-Reply-To: <1517348383-112294-1-git-send-email-dstolee@microsoft.com>

Teach git the 'commit-graph' builtin that will be used for writing and
reading packed graph files. The current implementation is mostly
empty, except for a '--pack-dir' option.
