Of course, thanks.

Regarding "this distribution": if I obtain a copy of the Mercury Core
Libraries from an intermediary (e.g. a Linux distribution), is that the
same distribution or a new distribution? If the latter, do we have to
add anything to ensure the special exception extends to the
re-distributed Mercury Core Libraries, or is clause 10 is enough?
