Name

Syntax: name <object> as <name>
       unname <object>

With this command you can name an object. After that, you can refer to it
as "name" (INCLUDING the quotation marks). The name cannot be longer than
ten letters, and you can only name objects you are carrying. The 'unname'
command removes the name. Do not confuse this with having a piece of
equipment marked by a smith; markings are permanent, while names given with
the 'name'- command can be changed.

To handle named items, use "" around the name. For example, if you named
your torch as Slayer, you can do: 'give "Slayer" to idles'

Note: Giving objects offensive names and showing them publicly might be bad
for your health.
