usage:
- .../ypp-restock-rum [<prices>] [<ship> <stocks>]
-where
- <prices> is three arguments: the prices for swill, grog and fine rum
- <ship> is a ship name or an amount of fine rum
- <stocks> are amounts on board for swill, grog and fine rum
+ .../ypp-restock-rum [<information> ...]
+
+where <information> is
+
+ have [<swill> <grog>] <fine> [<hold_shot>+<loaded_shot>]
+ want [<swill> <grog>] <fine> [<shot>]
+ price <swill> <grog> <fine> [<shot>]
+
+Each of which may appear only once, except \`have' which may appear
+more than once which case we calculate the financial implications
+at each stage.
+
+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.
