Oops, yes. I didn't write that, and it doesn't convey my feelings
about file() vs. open(). Here's a suggestion for better words:
"The file class is new in Python 2.2. It represents the type (class)
of objects returned by the built-in open() function. Its constructor
is an alias for open(), but for future and backwards compatibility,
open() remains preferred."
