+Missing entries count as zero (and zeroes are not displayed in the output).
+In price, \`x' means the commodity is unavailable.
+
+The intended use is that at the start of the pillage you run:
+   ypp-restock-rum have ... want ...
+to check that stocks are sufficient, or perhaps:
+   ypp-restock-rum have ... want ... price ...
+if you want to stock up some more.  At the end of the pillage,
+run the same thing again with some extra parameters:
+   ypp-restock-rum have .. want ... have ... price ...
+and it will tell you how you did and what the restock should be like.
