For each ref namespace, git stores the corresponding +refs in a directory under `refs/namespaces/`. For example, +`GIT_NAMESPACE=foo` will store refs under `refs/namespaces/foo/`. You +can also specify namespaces via the `--namespace` option to +linkgit:git[1]. + +Note that namespaces which include a `/` will expand to a hierarchy of +namespaces; for example, `GIT_NAMESPACE=foo/bar` will store refs under +`refs/namespaces/foo/refs/namespaces/bar/`.
