/*
 * Wizard routines for creating objects and modifying them
 *
 * This has been rewritten to make the whole procedure
 * of debugging objects much easier and more comfortable.
 *
 * Here are the low-level functions
 *
 * - wiz_display_item()
 *     display an item's debug-info
 * - wiz_create_itemtype()
 *     specify tval and sval (type and subtype of object)
 * - wiz_tweak_item()
 *     specify pval, p2val, +AC, +tohit, +todam
 *     Note that the wizard can leave this function anytime,
 *     thus accepting the default-values for the remaining values.
 *     pval and p2val come first now, since they are the most important.
 * - wiz_reroll_item()
 *     apply some magic to the item or turn it into an artifact.
 * - wiz_roll_item()
 *     Get some statistics about the rarity of an item:
 *     We create a lot of fake items and see if they are of the
 *     same type (tval and sval), then we compare pval, p2val and +AC.
 *     If the fake-item is better or equal it is counted.
 *     Note that cursed items that are better or equal (absolute values)
 *     are counted, too.
 *     HINT: This is *very* useful for balancing the game!
 * - wiz_quantity_item()
 *     change the quantity of an item, but be sane about it.
 *
 * And now the high-level functions
 * - do_cmd_wiz_play()
 *     play with an existing object
 * - wiz_create_item()
 *     create a new object
 *
 * Note -- You do not have to specify "pval" and other item-properties
 * directly. Just apply magic until you are satisfied with the item.
 *
 * Note -- For some items (such as wands, staffs, some rings, etc), you
 * must apply magic, or you will get "broken" or "uncharged" objects.
 *
 * Note -- Redefining artifacts via "do_cmd_wiz_play()" may destroy
 * the artifact.  Be careful.
 *
 * Hack -- this function will allow you to create multiple artifacts.
 * This "feature" may induce crashes or other nasty effects.
