-The popen2.Popen3 and popen2.Popen4 basically works as subprocess.Popen,
-except that:
-
-\begin{itemize}
-\item subprocess.Popen raises an exception if the execution fails
-
-\item the \var{capturestderr} argument is replaced with the \var{stderr}
- argument.
-
-\item stdin=PIPE and stdout=PIPE must be specified.
-
-\item popen2 closes all file descriptors by default, but you have to
- specify close_fds=True with subprocess.Popen.
