A "User Product" is either (1) a "consumer product", which means any tangible personal property
which is normally used for personal, family, or household purposes, or (2) anything designed or sold
for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful
cases shall be resolved in favor of coverage. For a particular product received by a particular user,
"normally used" refers to a typical or common use of that class of product, regardless of the status of
the particular user or of the way in which the particular user actually uses, or expects or is expected
to use, the product. A product is a consumer product regardless of whether the product has
substantial commercial, industrial or non-consumer uses, unless such uses represent the only
significant mode of use of the product.
"Installation Information" for a User Product means any methods, procedures, authorization keys, or
other information required to install and execute modified versions of a covered work in that User
Product from a modified version of its Corresponding Source. The information must suffice to ensure
that the continued functioning of the modified object code is in no case prevented or interfered with
solely because modification has been made.
If you convey an object code work under this section in, or with, or specifically for use in, a User
Product, and the conveying occurs as part of a transaction in which the right of possession and use
of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how
the transaction is characterized), the Corresponding Source conveyed under this section must be
accompanied by the Installation Information. But this requirement does not apply if neither you nor
any third party retains the ability to install modified object code on the User Product (for example, the
work has been installed in ROM).
The requirement to provide Installation Information does not include a requirement to continue to
provide support service, warranty, or updates for a work that has been modified or installed by the
recipient, or for the User Product in which it has been modified or installed. Access to a network may
be denied when the modification itself materially and adversely affects the operation of the network
or violates the rules and protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided, in accord with this section
must be in a format that is publicly documented (and with an implementation available to the public in
source code form), and must require no special password or key for unpacking, reading or copying.
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
