@@ -63,15 +70,17 @@ Item, over, and back require a little more explanation: "=over" starts a
 section specifically for the generation of a list using "=item" commands. At
 the end of your list, use "=back" to end it. You will probably want to give
 "4" as the number to "=over", as some formatters will use this for indentation.

-items consistent: either use "=item *" for all of them, to produce bullets,
