 \code{sys.stderr}.

! \code{sys.excepthook} is called when an exception is raised
! and uncaught. In an interactive session this happens just before
 control is returned to the prompt; in a Python program this happens
 just before the program exits.
 The handling of such top-level exceptions can be customized by
! assigning another function to \code{sys.excepthook}.
 \end{funcdesc}

--- 59,70 ----
 \code{sys.stderr}.

! When an exception is raised and uncaught, the interpreter calls
! \code{sys.excepthook} with three arguments, the exception class,
! exception instance, and a traceback object.
! In an interactive session this happens just before
 control is returned to the prompt; in a Python program this happens
 just before the program exits.
 The handling of such top-level exceptions can be customized by
! assigning another three-argument function to \code{sys.excepthook}.
