The Corresponding Source for a work in source code
form is that same work.
2. Basic Permissions.
All rights granted under this License are granted for the
term of copyright on the Program, and are irrevocable
provided the stated conditions are met. This License
explicitly affirms your unlimited permission to run the
unmodified Program. The output from running a
covered work is covered by this License only if the
output, given its content, constitutes a covered work.
This License acknowledges your rights of fair use or
other equivalent, as provided by copyright law.
You may make, run and propagate covered works that
you do not convey, without conditions so long as your
license otherwise remains in force. You may convey
covered works to others for the sole purpose of having
them make modifications exclusively for you, or provide
you with facilities for running those works, provided that
you comply with the terms of this License in conveying
all material for which you do not control copyright.
Those thus making or running the covered works for
you must do so exclusively on your behalf, under your
direction and control, on terms that prohibit them 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:
The work must carry prominent notices stating
that you modified it, and giving a relevant date.
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”.
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.
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:
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.
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
