I'll get the lawyers to comment on this in more detail, but here are
some answers as I understand them:
Big picture: it has been vetted by lawyers for reducing ambiguity
and risk for corporate legal departments, while protecting Boost
developers by disclaiming implicit guarantees.
It uses the correct legal terms for granting copy rights: "use,
reproduce, display, distribute, execute, and transmit"...
It is explicit about the differing requirements on source
vs. object code.

Sure, at some level. Contributors want to guarantee nothing and legal
departments want us to guarantee everything. Everyone benefits from
better clarity, though, and that's what this license accomplishes.

The 2nd one, IMO, because it doesn't hurt contributors at all while
it helps the legal departments. In fact, it probably helps
contributors by giving them a standard license with some legal
foundation behind it that is less likely to cause legal SNAFUs

I don't think we have to choose. Nobody is willing to sacrifice
contribution to the interests of corporate users, AFAICT, but IMO we
can make the legal situation more solid and that will smooth things

Just my opinion, but yes: it means that legal departments are getting
communication in a language they understand and aggressive lawyers are
less likely to mess with us.

I'm not sure about that. The problem is that the old version didn't
distinguish source code copies from object code copies.

Good point. A simple "copies of the source" might work better than
the wording we have now.

Heh. Did that point kill this discussion <wink> ? I'll ask the

Some, IIUC. Remember that the law here is applied in civil suits, so
the kind of protection you need is "discourages lawyers from suing
because it weakens their case". That's what the disclaimer does.

I don't understand that.
