* 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 meaning of section 10. If the Program as you received it, or any part of it, contains
a notice stating that it is governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains a further
restriction but permits relicensing or conveying under this License, you may add to a
covered work material governed by the terms of that license document, provided that
the further restriction does not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you must place, in the
relevant source files, a statement of the additional terms that apply to those files, or a
notice indicating where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the form of a
separately written license, or stated as exceptions; the above requirements apply either
way.
8. Termination.
You may not propagate or modify a covered work except as expressly provided
under this License. Any attempt otherwise to propagate or modify it is void, and will
automatically terminate your rights under this License (including any patent licenses
granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your license from a particular
copyright holder is reinstated (a) provisionally, unless and until the copyright holder
explicitly and finally terminates your license, and (b) permanently, if the copyright holder
fails to notify you of the violation by some reasonable means prior to 60 days after the
cessation.
Moreover, your license from a particular copyright holder is reinstated permanently if
the copyright holder notifies you of the violation by some reasonable means, this is the
first time you have received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after your receipt of the
notice.
Termination of your rights under this section does not terminate the licenses of parties
who have received copies or rights from you under this License. If your rights have been
terminated and not permanently reinstated, you do not qualify to receive new licenses
for the same material under section 10.
