To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction witha 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 prominentlyvisible 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 acopy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the listmeets this criterion.. Source Code.The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means anynon-sourceform of a work.A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in thecase of interfaces specified for a particular programming language, one that is widely used among developers working in thatlanguage.The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in thenormal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enableuse of the work with that Major Component, or to implement a Standard Interface for which an implementation is available tothe public in source code form. A “Major Component”, in this context, means a major essential component (kernel, windowsystem, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to producethe 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 anexecutable work) run the object code and to modify the work, including scripts to control those activities. However, it does notinclude the work’s System Libraries, or general-purpose tools or generally available free programs which are used unmodifiedin performing those activities but which are not part of the work. For example, Corresponding Source includes interfacedefinition files associated with source files for the work, and the source code for shared libraries and dynamically linkedsubprograms that the work is specifically designed to require, such as by intimate data communication or control flow betweenthose subprograms and other parts of the work.The Corresponding Source need not include anything that users can regenerate automatically from other parts of theCorresponding Source.The Corresponding Source for a work in source code form is that same work.. Basic Permissions.All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided thestated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The outputfrom 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 andpropagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. Youmay convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provideyou with facilities for running those works, provided that you comply with the terms of this License in conveying all materialfor which you do not control copyright. Those thus making or running the covered works for you must do so exclusively onyour behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted materialoutside 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.. 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 obligationsunder article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restrictingcircumvention of such measures.When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extentsuch circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim anyintention 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.. Conveying Verbatim Copies.You may convey verbatim copies of the Program’s source code as you receive it, in any medium, provided that youconspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that thisLicense and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absenceof 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 afee.. 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 codeunder 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 undersection 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.––
