License Information
To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring
copyright permission, other than the making of an exact copy. The resulting work is called a
“modified version” of the earlier work or a work “based on” the earlier work.
A “covered work” means either the unmodified Program or a work based on the Program.
To “propagate” a work means to do anything with it that, without permission, would make you
directlyor secondarilyliable forinfringement underapplicablecopyright law,except executingit
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 anykind of propagation that enables otherparties 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 thatthere is no warrantyfor the work (exceptto the extent
that warrantiesare provided), that licenseesmay convey thework under thisLicense, and howto
view acopy of thisLicense. Ifthe interface presentsa listof user commandsor 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 ofthe 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 anexecutable work include anything, other than thework as a whole,
that (a) isincluded in the normalform of packaginga Major Component, butwhich is not partof
that Major Component,
and (b) serves only to enable use of the work with that Major Component, or to implement a
Standard Interface forwhich an implementation is available tothe public in source codeform. 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 workin object code formmeans all the sourcecode 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, andthe source codefor sharedlibraries and dynamicallylinked subprograms thatthe 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 permissionto run theunmodified Program.The output fromrunning a covered workis
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, withoutconditions so
long asyour license otherwiseremains in force.You mayconvey covered worksto others forthe
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
