By default, a work is copyrighted regardless of whether that copyright
is expressed or claimed. I don't see anything in the documentation that
actually gives permission to use it, much less copy or modify it. Of
course, that's not what the author wants. It would be best to contact
the author and ask him to agree to "rerelease" it under an actual
license, Scipy's for preference.

Every time I use a new Python installation, I'm never sure if I've
installed it or where to get it again. It's useful for when you are
evaluating an expression a few times and want to get that extra digit or
20.
