The normal os.popen(cmd, mode) call spawns a shell command and provides a
file interface to just the input or output of the process depending on
whether mode is 'r' or 'w'.  This module provides the functions popen2(cmd)
and popen3(cmd) which return two or three pipes to the spawned command.
i�Ns<The popen2 module is deprecated.  Use the subprocess module.t

        sub-process.  On UNIX, 'cmd' may be a sequence, in which case arguments
        will be passed directly to the program without shell intervention (as
        with os.spawnv()).  If 'cmd' is a string it will be passed to the shell
        (as with os.system()).   The 'capturestderr' flag, if true, specifies
        that the object should capture standard error output of the child
        process.  The default is false.  If the 'bufsize' parameter is
        specified, it specifies the size of the I/O buffers to/from the child
        process.iiitwtrN(R
