Thanks. I didn't realize that. The text as it stands is uncomfortable.

That's vastly clearer, or at least aligned with normal language. If
you are able to get the language updated (I know that can be hard), that
would be great.

I don't have any desire to depart from upstream defaults. I just
updated from 1.18 to 1.18.2 and ran our lint program which told me that
we don't set a license tag, so I read it, and then my head hurt.
As an aside, if there were some consolidation of licensing, or at least
a summary in NOTICE of the license flavors, that would help people to
more rapidly understand that this qualifies overall as non-copyleft Free
Software, that is some blend of X11 license, 3-clause BSD, 4-clause BSD,
and others that are similar enough that if you are ok with those three,
you won't mind. At least that was my sense from a too-quick read.
Thanks,
Greg
