 	Print the parents of the commit.
 
+--left-right::
+
+	Mark which side of a symmetric diff a commit is reachable from.
+	Commits from the left side are prefixed with `<` and those from
+	the right with `>`.  If combined with `--boundary`, those
+	commits are prefixed with `-`.
++
+For example, if you have this topology:

+-----------------------------------------------------------------------
