 DESCRIPTION
 -----------
+The command takes various subcommands, and different options
+depending on the subcommand:
+
+[verse]
+git reflog expire [--dry-run] [--stale-fix]
+	[--expire=<time>] [--expire-unreachable=<time>] [--all] <refs>...
+
+git reflog [show] [log-options]
 
 Reflog is a mechanism to record when the tip of branches are
 updated.  This command is to manage the information recorded in it.
@@ -25,11 +30,28 @@ Entries older than `expire` time, or entries older than
 tip, are removed from the reflog.  This is typically not used
 directly by the end users -- instead, see gitlink:git-gc[1].
 
+The subcommand "show" (which is also the default, in the absense of any
+subcommands) will take all the normal log options, and show the log of
+the current branch. It is basically an alias for 'git log -g --abbrev-commit
+--pretty=oneline', see gitlink:git-log[1].
 
 
 OPTIONS
 -------
 
+--stale-fix::
+	This revamps the logic -- the definition of "broken commit"
+	becomes: a commit that is not reachable from any of the refs and
+	there is a missing object among the commit, tree, or blob
+	objects reachable from it that is not reachable from any of the
+	refs.
++
+This computation involves traversing all the reachable objects, i.e. it
+has the same cost as 'git prune'.  Fortunately, once this is run, we
+should not have to ever worry about missing objects, because the current
+prune and pack-objects know about reflogs and protect objects referred by
+them.
+
 --expire=<time>::
 	Entries older than this time are pruned.  Without the
 	option it is taken from configuration `gc.reflogExpire`,
