+% 2.  You can use \foxlevel to access the level/depth of nesting.
+% 3.  You can inset \csvbreak as an element of <list> to break
+%     out of the loop. Similarly, you can use \loopbreak within
+%     <callback> to break out of the loop.
+% 4.  You can insert \csvpause as an element of <list> to pause
