\code{sys.exitfunc} variable.

Note: This module is unlikely to work correctly when used with other code
that sets \code{sys.exitfunc}. In particular, other core Python modules are
free to use \module{atexit} without the programmer's knowledge. Authors who
use \code{sys.exitfunc} should convert their code to use
\module{atexit} instead. The simplest way to convert code that sets
\code{sys.exitfunc} is to import \module{atexit} and register the function
that had been bound to \code{sys.exitfunc}.
\begin{funcdesc}{register}{func\optional{, *args\optional{, **kargs}}}
Register \var{func} as a function to be executed at termination. Any
optional arguments that are to be passed to \var{func} must be passed
