Python subprocess emulating a filter.
infile = open(inputfilename, "r")
outfile = open(outputfilename, "w")
filter1 = subprocess.Popen(commandline1, stdin=infile, stdout=subprocess.PIPE, stderr=None)
filter2 = subprocess.Popen(commandline2, stdin=filter1.stdout, stdout=outfile, stderr=None)
filter1.stdout.close() # required so filter2 can get SIGPIPE, apparently
filter1.wait()
filter2.wait()
