put and get are variables that receive the result of the call to
popen4(). The docs for popen4() are here:
http://docs.python.org/lib/os-newstreams.html#os-newstreams

It says popen4() "returns the file objects (child_stdin,
child_stdout_and_stderr)", so put is linked to stdin for the child
process.
