Examples 
-------- 

Igor is a new player. He sets his description by typing:

@desc me=Igor is a ferret with an evil glint in his eye.

Igor wants to make an object called 'Ferret chow'. He types:

@create Ferret Chow 
@desc Ferret Chow=This is a big bag full of yummy ferret chow.  
@succ Ferret Chow=You tear into the end of the bag, stuffing yourself. 
@osucc Ferret Chow=tears into the Ferret Chow bag, eating greedily. 

Now Igor decides that he wants to be the only one who can pick up the 
bag. 

@lock Ferret Chow=me
@fail Ferret Chow=It's icky Ferret Chow. It would probably taste 
gross. 
@ofail Ferret Chow=decides Ferret Chow is icky. 

If Igor picks up the bag: Igor types:   

get Ferret Chow

Igor sees:    

You tear into the end of the bag, stuffing yourself. 

all else see: 

Igor tears into the Ferret Chow bag, eating greedily.

Igor is now carrying the bag. He must drop it if he wants to see the 
messages again.  If Murf picks up the bag: Murf types: 

get Ferret Chow

Murf sees:    

It's icky Ferret Chow. It would probably taste gross.

all else see:

Murf decides Ferret Chow is icky.

Because the bag was locked to Igor, Murf cannot get the bag.
