-This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License. The ``Program'', below,
-refers to any such program or work, and a ``work based on the Program''
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language. (Hereinafter, translation is included without limitation in
-the term ``modification''.) Each licensee is addressed as ``you''.
-.Sp
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-.Ip "1." 4
-You may copy and distribute 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 and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-.Sp
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-.Ip "2." 4
-You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
+The \s-1GNU\s0 General Public License is a free, copyleft license for

+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 \s-1GNU\s0 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 \s-1GNU\s0 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.
+.PP
+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.
+.PP
+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.
+.PP
+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.
+.PP
+Developers that use the \s-1GNU\s0 \s-1GPL\s0 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.
+.PP
+For the developers' and authors' protection, the \s-1GPL\s0 clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the \s-1GPL\s0 requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+.PP
+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 \s-1GPL\s0 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 \s-1GPL\s0, as needed to protect the
+freedom of users.
+.PP
+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 \s-1GPL\s0
+assures that patents cannot be used to render the program non-free.

+\&\*(L"This License\*(R" refers to version 3 of the \s-1GNU\s0 General Public License.
+.Sp
+\&\*(L"Copyright\*(R" also means copyright-like laws that apply to other kinds
+of works, such as semiconductor masks.
+.Sp
+\&\*(L"The Program\*(R" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as \*(L"you\*(R". \*(L"Licensees\*(R" and
+\&\*(L"recipients\*(R" may be individuals or organizations.
+.Sp
+To \*(L"modify\*(R" 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 \*(L"modified version\*(R" of
+the earlier work or a work \*(L"based on\*(R" the earlier work.
+.Sp
+A \*(L"covered work\*(R" means either the unmodified Program or a work based
+on the Program.
+.Sp
+To \*(L"propagate\*(R" 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.
+.Sp
+To \*(L"convey\*(R" 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.
+.Sp
+An interactive user interface displays \*(L"Appropriate Legal Notices\*(R" 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

+The \*(L"source code\*(R" for a work means the preferred form of the work for

+of a work.
+.Sp
+A \*(L"Standard Interface\*(R" 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.
+.Sp
+The \*(L"System Libraries\*(R" 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
+\&\*(L"Major Component\*(R", 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.
+.Sp
+The \*(L"Corresponding Source\*(R" 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.
+.Sp
+The Corresponding Source need not include anything that users can
+regenerate automatically from other parts of the Corresponding Source.

+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.

+measures.
+.Sp
+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
