Can you elaborate on this? I have some very simple command-line utilities I
would like to make available on different platforms, but what little I knew
about Windows is fading into the past.

This example:

    import sys
    print sys.stdin.read()

...works in the Windows XP dos box if I do:

    python demo.py < file.txt

...but I get the error 9 for:

    demo.py < file.txt

Is there any way to make the second version work on Windows?
