Well spotted. See also:

That starts:

# DerivedCoreProperties-5.2.0.txt
# Date: 2009-08-26, 00:45:22 GMT [MD]
# Unicode Character Database

# It is ok to redistribute this file "solely for informational

# We don't nee to add a Boost License to this file: boostinspect:nolicense.

Note that I don't know who wrote that, nor where the "solely for
informational purposes..." quote comes from. And what are
"informational purposes" anyway? - it doesn't sound to me as
if that were written by a lawyer.

This really needs an expert to look at it, IMO.

Regards, Phil.
