Subject: [PATCH v8 05/14] commit-graph: create git-commit-graph builtin
Date: Tue, 10 Apr 2018 08:55:59 -0400
Message-ID: <20180410125608.39443-6-dstolee@microsoft.com> (raw)
In-Reply-To: <20180410125608.39443-1-dstolee@microsoft.com>

From: Derrick Stolee <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 an '--object-dir' option.
