The sell command sells an item to a shopkeeper. Most items sell back for
half of the original cost of the item. Drink and food sell back for 10% of
their original price, jewelry sells back for 80% its cost, and treasures
sell back at full price. Quest items can only be sold at questpoint
shopkeepers and will sell back for half their original cost. Shopkeepers
will only accept an item if they themselves sell that item type.
The command 'sell *all*' will attempt to sell all of the items in your
inventory. Bags which contain items must be emptied before being sold.
Using 'sell all.<keyword>' such as 'sell all.po' will attempt to sell any
item in your inventory which has a keyword matching 'po'.
It's also possible to sell all of an item type using keywords prefixed with
the number sign, such as 'sell all.#weapon' to sell weapons.
Syntax: value <object>
The value command asks the shopkeeper how much he, she, or it will buy the
item for. This does not include extra gold earned through the haggle skill.
