... or as

    sys.stdout = TeeStream(sys.stdout, open('myfile.txt', "w")

in which case print should work as standard, whearas the original example
requires

    print >> stream, things

BTW, was TeeStream (sys.stdout, open ('...', 'wt')) a typo? Don't see any
't' mode character in the docs for file()/open().
