/* the ordering of this is actually doesn't make a difference
 * However, for ease of use, new entries should go at the end
 * so those people that debug the code that get used to something
 * being in the location 4 don't get confused.
 *
 * The ordering in save_name, use_name, nonuse_name.
 * save_name is the name used to load/save it from files.  It should
 * match that of the doc/Developers/objects.  The only
 * real limitation is that it shouldn't have spaces or other characters
 * that may mess up the match code.  It must also start with body_
 * use_name is how we describe the location if we can use it.
 * nonuse_name is how we describe it if we can't use it.  I think
 * the values below will make it pretty clear how those work out
 * They are basically there to make life a little easier - if a character
 * examines an item and it says it goes on 'your arm', its pretty clear
 * they can use it.  See the last sample (commented out) for a dragon
 * Note that using the term 'human' may not be very accurate, humanoid
 * may be better.
 * Basically, for the use/nonuse, the code does something like:
 * "This item goes %s\n", with the use/nonuse values filling in the %s
