7. Additional Terms.
'Additional permissions' are terms that supplement the terms of this License by making
exceptions from one or more of its conditions. Additional permissions that are applicable
to the entire Program shall be treated as though they were included in this License, to
the extent that they are valid under applicable law. If additional permissions apply only
to part of the Program, that part may be used separately under those permissions, but
the entire Program remains governed by this License without regard to the additional
permissions.
When you convey a copy of a covered work, you may at your option remove any
additional permissions from that copy, or from any part of it. (Additional permissions may
be written to require their own removal in certain cases when you modify the work.) You
may place additional permissions on material, added by you to a covered work, for which
you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you add to a covered
work, you may (if authorized by the copyright holders of that material) supplement the
terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16
of this License; or
b) Requiring preservation of specified reasonable legal notices or author attributions in
that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or requiring that modified
versions of such material be marked in reasonable ways as different from the original
version; or
d) Limiting the use for publicity purposes of names of licensors or authors of the material;
or
e) Declining to grant rights under trademark law for use of some trade names,
trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by anyone who
conveys the material (or modified versions of it) with contractual assumptions of liability
to the recipient, for any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered 'further restrictions' within the
