Haskell API for memory useage

I don't want to do this in the shell, but if I did "-RTS -t" already
dumps it to a file and I can get the answer from there.

The example I want is:

do
     x <- getCPUTime
     compute
     y <- getCPUTime
     z <- getMemoryUse
     print "Your computation took {y-x}ms and {z}kb"

Thanks
