from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is
permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such
measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the
extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any
intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal
rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-
permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you
may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under
the terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This
requirement modifies the requirement in section 4 to “keep intact all notices”.
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will
therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they
are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you
have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with
other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined
with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the
compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the
individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the
aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-
readable Corresponding Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written
offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give
anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is
covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your
reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network
server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is
allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection
6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear
directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding
Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and
Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of
the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in
conveying the object code work. 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
