Syntax: sell <object>
Syntax: value <object>
BUY buys an object from a shop keeper.
When multiple items of the same name are listed, type 'buy N.item', where N
is the position of the item in a list of that name. So if there are two
swords, buy 2.sword will buy the second. If you want to buy multiples of
an item, use an * (buy 5*pie will buy 5 pies). These can be combined into
(for example) buy 2*2.shield, as long as the * is first.
LIST lists the objects the shopkeeper will sell you.
List <name> shows you only objects of that name.
SELL sells an object to a shopkeeper.
VALUE asks the shopkeeper how much he, she, or it will buy the item for.
