time command output

[David Rich]

What do the numbers mean in the output of the (csh) time
command? The documentation simply says that you get user,
system and elapsed time (along with a "utilization" percentage).
How do these numbers relate to each other (typically, user and
system don't add up to elapsed)? What are the other numbers?
pf=page faults? io?

In general, what do these numbers say about a particular
application?

e.g., 52.7u 15.4s 1:59 56% 0+3092k 33+0io 102pf+0w
