I do 'man python', and the first thing I see is
-B Don't write .py[co] files on import. See also PYTHONDONTWRITEBYTECODE.
I'd say, go for it! Unfortunately, you can't add it directly in the #!
line of the script because all the arguments are concatenated together.
So I guess the PYTHONDONTWRITEBYTECODE environment variable should be set
when calling the script.
