+\section{PEP 324: New subprocess Module}
+
+The standard library provides a number of ways to
+execute a subprocess, each of which offers different features and
+levels of difficulty. \function{os.system(\var{command})} is easy, but
+slow -- it runs a shell process which executes the command --
+and dangerous -- you have to be careful about escaping metacharacters.
+The \module{popen2} module offers classes that can capture
+standard output and standard error from the subprocess, but the naming
+is confusing.
+
+The \module{subprocess} module cleans all this up, providing a unified
+interface that offers all the features you might need.
+
+% XXX finish writing this section by adding some examples
