Subject: [PATCH v4 5/5] Reftable support for git-core
Date: Thu, 06 Feb 2020 22:55:56 +0000
Message-ID: <2786a6bf61d732570335f181540b0d1f7dd47b13.1581029756.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.539.v4.git.1581029756.gitgitgadget@gmail.com>

From: Han-Wen Nienhuys <hanwen@google.com>

For background, see the previous commit introducing the library.

TODO:

 * Make CI on gitgitgadget compile.
 * Redo interaction between repo config, repo storage version
 * Resolve the design problem with reflog expiry.
 * Resolve spots marked with XXX

Example use:
