Boost smart pointers.

Hello All,
 I have been trying to understand the smart pointer library. One thing that
I did not understand was in the documentationin quite beginning:

"T may be an incomplete type at the point of smart pointer declaration.
Unless otherwise specified, it is required that T be a complete type at
points of smart pointer instantiation."

 So what exactly does this incomplete/complete type mean?  Does this have
anything to do with  the class pointed to being abstract /concrete ?

thanks,
regards,
amit.
