+
+```
+[core]
+	repositoryformatversion = 0
+	filemode = true
+	bare = false
+	logallrefupdates = true
+[remote \"origin\"]
+	url = m0:/mnt/a/annex.git
+	fetch = +refs/heads/*:refs/remotes/origin/*
+	annex-uuid = c5c012cc-2080-481f-81bc-7f449f33490b
+[branch \"master\"]
+	remote = origin
+	merge = refs/heads/master
+[annex]
+	uuid = a71d805d-df77-42e7-97b0-ba7686c05083
+	version = 5
