* The [[git-annex assistant|assistant]] is included in git-annex,
  and extends its use cases into new territory.
 
* [gitlab-shell](https://gitlab.com/gitlab-org/gitlab-shell) supports
  git-annex. So git-annex can be used with repositories served by GitLab,
  including gitlab.com, or deploy your own.
