BSD like license with strange wording?

[Robert-André Mauchin]

Hi,

The following license is lifted from a code coming from NetBSD 
(ftp://ftp.NetBSD.org/pub/NetBSD/misc/sjg/ ) but I cannot find exactly 
the text of this license anywhere else:

#	This file is provided in the hope that it will
#	be of use.  There is absolutely NO WARRANTY.
#	Permission to copy, redistribute or otherwise
#	use this file is hereby granted provided that
#	the above copyright notice and this notice are
#	left intact.

Is this considered BSD-like?

Best regards,

Robert-André

It doesn't say anything about modification.  I think it's non-free
because of that.

Thanks,
Florian

Maybe! How old is it?

There's a loose precedent of accepting these sorts of short permissive
licenses so long as there's nothing to indicate that they're intending
to disallow modification. "Otherwise use" could certainly be construed
to permit modification in this case. But it's generally applied to
text from, say, 25ish years ago. So if it's very old, we could permit
it. If it's from this century, it's probably better for upstream to
put a "real" license on it.

FYI: I managed to contact upstream and should be able to get an explicit answer in the coming days.

That's great! Thanks for working with upstream on this, Timothée.

Robert-André, you can proceed with this as a BSD-like license.
