  A window is a rectangular portion of the physical terminal
! screen associated with a set of processes.  Its size and
! position can be changed by the user at any time.  Processes
  communicate with their window in the same way they normally
  interact with a terminal - through their standard input, output,
! and diagnostic file descriptors.  The window program handles the
  details of redirecting input and output to and from the
! windows.  At any one time, only one window can receive
  input from the keyboard, but all windows can simultaneously send output
  to the display.
