This is probably just an artifact of the software distribution area that
we maintain for a whole bunch of different tools. Sfio is completely free.
If you include its source in your distribution, then you must include the
included copyright notice.  That's all.

Me neither. But is true that Sfio offers no warranty. You use it
at your own risk.


Ok, I will start engineering study ( = open the package and read documents )
about how to use it, and how large an impact it will be when linked into
programs.  (In terms of binary footprint.)

Indeed ATT Research does have a habit of publishing some of its products
in BSD-like licenses where credit is called for, but no other strings are

Ken, thanks for the pointer!
