20 | # \ \ / / | |

23 | # | |
24 | # The commits are laid out from left-to-right starting with | |
25 | # the root commit A and terminating at the tip commit L. | |
26 | # | |
27 | # There are a few places where we adjust the commit date or | |
28 | # author date to make the --topo-order, --date-order, and | |
29 | # --author-date-order flags produce different output. | |
