    /* We have implemented our 'metal' property as an

    AppleScript enumeration.  As such, each of the items in the

    enumeration is identified by a unique four character code

    stored in a long integer.

    The following enumeration lists those four character codes

    that we have defined in our scripting definition file.  We can

    use these codes to decode the enumeration values we receive

    from Cocoa */

    kTinMetal = 'PmTn',

    /* The Treasure class adds a few new properties to the Trinket class.

    One point of interest in this class is the metal property that uses

    an AppleScript enumeration.  The decodeMetal class method illustrates

    how you can decode enumeration values and use them in your program.

    We take care of most of the 'infrastructure' type operations

    needed for scripting in the Element class (the superclass of the

    Trinket class), so all we have to worry about here is storage management

    and providing accessors for the properties.*/
