Reflog is a mechanism to record when the tip of branches are
updated. This command is to manage the information recorded in it.
Entries older than `expire` time, or entries older than
`expire-unreachable` time and are not reachable from the current
tip, are removed from the reflog. This is typically not used

The subcommand "show" (which is also the default, in the absence of any
subcommands) will take all the normal log options, and show the log of
-`HEAD`, which will cover all recent actions, including branch switches.

+The reflog is useful in various git commands, to specify the old value

+two moves ago", `master@\{one.week.ago\}` means "where master used to
+point to one week ago", and so on. See linkgit:git-rev-parse[1] for
