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
