7.    /* KMH -- Differences between the three weapon slots.
8.     *
9.     * The main weapon (uwep):
10.    * 1.  Is filled by the (w)ield command.
11.    * 2.  Can be filled with any type of item.
12.    * 3.  May be carried in one or both hands.
13.    * 4.  Is used as the melee weapon and as the launcher for
14.    *     ammunition.
15.    * 5.  Only conveys intrinsics when it is a weapon, weapon-tool,
16.    *     or artifact.
17.    * 6.  Certain cursed items will weld to the hand and cannot be
18.    *     unwielded or dropped.  See erodeable_wep() and will_weld()
19.    *     below for the list of which items apply.
20.    *
21.    * The secondary weapon (uswapwep):
22.    * 1.  Is filled by the e(x)change command, which swaps this slot
23.    *     with the main weapon.  If the "pushweapon" option is set,
24.    *     the (w)ield command will also store the old weapon in the
25.    *     secondary slot.
26.    * 2.  Can be field with anything that will fit in the main weapon
27.    *     slot; that is, any type of item.
28.    * 3.  Is usually NOT considered to be carried in the hands.
29.    *     That would force too many checks among the main weapon,
30.    *     second weapon, shield, gloves, and rings; and it would
31.    *     further be complicated by bimanual weapons.  A special
32.    *     exception is made for two-weapon combat.
33.    * 4.  Is used as the second weapon for two-weapon combat, and as
34.    *     a convenience to swap with the main weapon.
35.    * 5.  Never conveys intrinsics.
36.    * 6.  Cursed items never weld (see #3 for reasons), but they also
37.    *     prevent two-weapon combat.
38.    *
39.    * The quiver (uquiver):
40.    * 1.  Is filled by the (Q)uiver command.
41.    * 2.  Can be filled with any type of item.
42.    * 3.  Is considered to be carried in a special part of the pack.
43.    * 4.  Is used as the item to throw with the (f)ire command.
44.    *     This is a convenience over the normal (t)hrow command.
45.    * 5.  Never conveys intrinsics.
46.    * 6.  Cursed items never weld; their effect is handled by the normal
47.    *     throwing code.
48.    *
49.    * No item may be in more than one of these slots.
