To$“propagate”$a$work$means$to$do$anything$with$it$that,$without$permission,$would$make$you$directly$or$secondarily$liable for infringement under applicable copyright
law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To$“convey”$a$work$means$any$kind$of$propagation$that$enables$other$parties$to$make$or$receive$copies.$Mere$interaction$with$a user through a computer network,
with no transfer of a copy, is not conveying.
An interactive user interface displays$“Appropriate$Legal$Notices”$to$the$extent$that$it$includes$a$convenient$and$prominently$visible$feature$that$(1)$displays an
appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey
the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in
the list meets this criterion.
1. Source Code.
The$“source$code”$for$a$work$means$the$preferred$form$of$the$work$for$making$modifications$to$it.$“Object$code”$means$any$non-source form of a work.
A$“Standard$Interface”$means$an$interface$that$either$is$an$official$standard$defined$by$a$recognized$standards body, or, in the case of interfaces specified for a
particular programming language, one that is widely used among developers working in that language.
The$“System$Libraries”$of$an$executable$work$include$anything,$other$than$the$work$as$a$whole,$that (a) is included in the normal form of packaging a Major
Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard
Interface for which an implementation is$available$to$the$public$in$source$code$form.$A$“Major$Component”,$in$this$context,$means$a$major$essential$component$(kernel,
window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code
interpreter used to run it.
The$“Corresponding$Source”$for$a$work$in$object$code$form$means$all$the$source$code$needed$to$generate,$install,$and$(for$an$executable work) run the object code
and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally
available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes
interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is
specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
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.
