-The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
+The GNU General Public License is a free, copyleft license for software and
+other kinds of works.
 
-The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works. By contrast,
-the GNU General Public License is intended to guarantee your freedom
-to share and change all versions of a program--to make sure it remains
-free software for all its users. We, the Free Software Foundation, use
-the GNU General Public License for most of our software; it applies
-also to any other work released this way by its authors. You can apply
-it to your programs, too.

+We, the Free Software Foundation, use the GNU General Public License for most
+of our software; it applies also to any other work released this way by its
+authors. You can apply it to your programs, too.
 
-When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.

+receive source code or can get it if you want it, that you can change the
+software or use pieces of it in new free programs, and that you know you can do
+these things.
 
-To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights. Therefore, you
-have certain responsibilities if you distribute copies of the
-software, or if you modify it: responsibilities to respect the freedom
-of others.
+To protect your rights, we need to prevent others from denying you these rights
+or asking you to surrender the rights. Therefore, you have certain
+responsibilities if you distribute copies of the software, or if you modify it:
+responsibilities to respect the freedom of others.
 
-For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received. You must make sure that they, too, receive
-or can get the source code. And you must show them these terms so they
-know their rights.

+You must make sure that they, too, receive or can get the source code. And you
+must show them these terms so they know their rights.
 
 Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
 
-For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software. For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.

+  2. offer you this License giving you legal permission to copy, distribute
+     and/or modify it.
 
-Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the
-manufacturer can do so. This is fundamentally incompatible with the
-aim of protecting users' freedom to change the software. The
-systematic pattern of such abuse occurs in the area of products for
-individuals to use, which is precisely where it is most unacceptable.
-Therefore, we have designed this version of the GPL to prohibit the
-practice for those products. If such problems arise substantially in
-other domains, we stand ready to extend this provision to those
-domains in future versions of the GPL, as needed to protect the
-freedom of users.

+the GPL requires that modified versions be marked as changed, so that their
+problems will not be attributed erroneously to authors of previous versions.
 
-Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish
-to avoid the special danger that patents applied to a free program
-could make it effectively proprietary. To prevent this, the GPL
-assures that patents cannot be used to render the program non-free.

-"recipients" may be individuals or organizations.
+*Copyright* also means copyright-like laws that apply to other kinds of works,
+such as semiconductor masks.
 
-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.
+*The Program* refers to any copyrightable work licensed under this License.
+Each licensee is addressed as *you*. *Licensees* and *recipients* may be

-A "covered work" means either the unmodified Program or a work based
-on the Program.
+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.
 
-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.
+A *covered work* means either the unmodified Program or a work based on the
+Program.
 
-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.
+To *propagate* a work means to do anything with it that, without permission,

-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.

+  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.
 
-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.
+If the interface presents a list of user commands or options, such as a menu, a
+prominent item in the list meets this criterion.
 
-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.
+### 1. Source Code.
 
-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 *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.
 
-The Corresponding Source need not include anything that users can
-regenerate automatically from other parts of the Corresponding Source.
+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 Corresponding Source for a work in source code form is that same
-work.
+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.
 
-#### 2. Basic Permissions.
+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

 ### How to Apply These Terms to Your New Programs

-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these
-terms.

-To do so, attach the following notices to the program. It is safest to
-attach them to the start of each source file to most effectively state
