 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |  Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
 | 
					
						
							|  |  |  |  |  Everyone is permitted to copy and distribute verbatim copies
 | 
					
						
							|  |  |  |  |  of this license document, but changing it is not allowed.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |                             Preamble
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   The precise terms and conditions for copying, distribution and
 | 
					
						
							|  |  |  |  | modification follow.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |                        TERMS AND CONDITIONS
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   0. Definitions.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   "This License" refers to version 3 of the GNU General Public License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   "Copyright" also means copyright-like laws that apply to other kinds of
 | 
					
						
							|  |  |  |  | works, such as semiconductor masks.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   "The Program" refers to any copyrightable work licensed under this
 | 
					
						
							|  |  |  |  | License.  Each licensee is addressed as "you".  "Licensees" and
 | 
					
						
							|  |  |  |  | "recipients" may be individuals or organizations.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   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 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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   You may charge any price or no price for each copy that you convey,
 | 
					
						
							|  |  |  |  | and you may offer support or warranty protection for a fee.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   5. 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 code under 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 under section
 | 
					
						
							|  |  |  |  |     7.  This requirement modifies the requirement in section 4 to
 | 
					
						
							|  |  |  |  |     "keep intact all notices".
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     c) You must license the entire work, as a whole, under this
 | 
					
						
							|  |  |  |  |     License to anyone who comes into possession of a copy.  This
 | 
					
						
							|  |  |  |  |     License will therefore apply, along with any applicable section 7
 | 
					
						
							|  |  |  |  |     additional terms, to the whole of the work, and all its parts,
 | 
					
						
							|  |  |  |  |     regardless of how they are packaged.  This License gives no
 | 
					
						
							|  |  |  |  |     permission to license the work in any other way, but it does not
 | 
					
						
							|  |  |  |  |     invalidate such permission if you have separately received it.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     d) If the work has interactive user interfaces, each must display
 | 
					
						
							|  |  |  |  |     Appropriate Legal Notices; however, if the Program has interactive
 | 
					
						
							|  |  |  |  |     interfaces that do not display Appropriate Legal Notices, your
 | 
					
						
							|  |  |  |  |     work need not make them do so.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   A compilation of a covered work with other separate and independent
 | 
					
						
							|  |  |  |  | works, which are not by their nature extensions of the covered work,
 | 
					
						
							|  |  |  |  | and which are not combined with it such as to form a larger program,
 | 
					
						
							|  |  |  |  | in or on a volume of a storage or distribution medium, is called an
 | 
					
						
							|  |  |  |  | "aggregate" if the compilation and its resulting copyright are not
 | 
					
						
							|  |  |  |  | used to limit the access or legal rights of the compilation's users
 | 
					
						
							|  |  |  |  | beyond what the individual works permit.  Inclusion of a covered work
 | 
					
						
							|  |  |  |  | in an aggregate does not cause this License to apply to the other
 | 
					
						
							|  |  |  |  | parts of the aggregate.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   6. Conveying Non-Source Forms.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   You may convey a covered work in object code form under the terms
 | 
					
						
							|  |  |  |  | of sections 4 and 5, provided that you also convey the
 | 
					
						
							|  |  |  |  | machine-readable Corresponding Source under the terms of this License,
 | 
					
						
							|  |  |  |  | in one of these ways:
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     a) Convey the object code in, or embodied in, a physical product
 | 
					
						
							|  |  |  |  |     (including a physical distribution medium), accompanied by the
 | 
					
						
							|  |  |  |  |     Corresponding Source fixed on a durable physical medium
 | 
					
						
							|  |  |  |  |     customarily used for software interchange.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     b) Convey the object code in, or embodied in, a physical product
 | 
					
						
							|  |  |  |  |     (including a physical distribution medium), accompanied by a
 | 
					
						
							|  |  |  |  |     written offer, valid for at least three years and valid for as
 | 
					
						
							|  |  |  |  |     long as you offer spare parts or customer support for that product
 | 
					
						
							|  |  |  |  |     model, to give anyone who possesses the object code either (1) a
 | 
					
						
							|  |  |  |  |     copy of the Corresponding Source for all the software in the
 | 
					
						
							|  |  |  |  |     product that is covered by this License, on a durable physical
 | 
					
						
							|  |  |  |  |     medium customarily used for software interchange, for a price no
 | 
					
						
							|  |  |  |  |     more than your reasonable cost of physically performing this
 | 
					
						
							|  |  |  |  |     conveying of source, or (2) access to copy the
 | 
					
						
							|  |  |  |  |     Corresponding Source from a network server at no charge.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     c) Convey individual copies of the object code with a copy of the
 | 
					
						
							|  |  |  |  |     written offer to provide the Corresponding Source.  This
 | 
					
						
							|  |  |  |  |     alternative is allowed only occasionally and noncommercially, and
 | 
					
						
							|  |  |  |  |     only if you received the object code with such an offer, in accord
 | 
					
						
							|  |  |  |  |     with subsection 6b.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     d) Convey the object code by offering access from a designated
 | 
					
						
							|  |  |  |  |     place (gratis or for a charge), and offer equivalent access to the
 | 
					
						
							|  |  |  |  |     Corresponding Source in the same way through the same place at no
 | 
					
						
							|  |  |  |  |     further charge.  You need not require recipients to copy the
 | 
					
						
							|  |  |  |  |     Corresponding Source along with the object code.  If the place to
 | 
					
						
							|  |  |  |  |     copy the object code is a network server, the Corresponding Source
 | 
					
						
							|  |  |  |  |     may be on a different server (operated by you or a third party)
 | 
					
						
							|  |  |  |  |     that supports equivalent copying facilities, provided you maintain
 | 
					
						
							|  |  |  |  |     clear directions next to the object code saying where to find the
 | 
					
						
							|  |  |  |  |     Corresponding Source.  Regardless of what server hosts the
 | 
					
						
							|  |  |  |  |     Corresponding Source, you remain obligated to ensure that it is
 | 
					
						
							|  |  |  |  |     available for as long as needed to satisfy these requirements.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     e) Convey the object code using peer-to-peer transmission, provided
 | 
					
						
							|  |  |  |  |     you inform other peers where the object code and Corresponding
 | 
					
						
							|  |  |  |  |     Source of the work are being offered to the general public at no
 | 
					
						
							|  |  |  |  |     charge under subsection 6d.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   A separable portion of the object code, whose source code is excluded
 | 
					
						
							|  |  |  |  | from the Corresponding Source as a System Library, need not be
 | 
					
						
							|  |  |  |  | included in conveying the object code work.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   A "User Product" is either (1) a "consumer product", which means any
 | 
					
						
							|  |  |  |  | tangible personal property which is normally used for personal, family,
 | 
					
						
							|  |  |  |  | or household purposes, or (2) anything designed or sold for incorporation
 | 
					
						
							|  |  |  |  | into a dwelling.  In determining whether a product is a consumer product,
 | 
					
						
							|  |  |  |  | doubtful cases shall be resolved in favor of coverage.  For a particular
 | 
					
						
							|  |  |  |  | product received by a particular user, "normally used" refers to a
 | 
					
						
							|  |  |  |  | typical or common use of that class of product, regardless of the status
 | 
					
						
							|  |  |  |  | of the particular user or of the way in which the particular user
 | 
					
						
							|  |  |  |  | actually uses, or expects or is expected to use, the product.  A product
 | 
					
						
							|  |  |  |  | is a consumer product regardless of whether the product has substantial
 | 
					
						
							|  |  |  |  | commercial, industrial or non-consumer uses, unless such uses represent
 | 
					
						
							|  |  |  |  | the only significant mode of use of the product.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   "Installation Information" for a User Product means any methods,
 | 
					
						
							|  |  |  |  | procedures, authorization keys, or other information required to install
 | 
					
						
							|  |  |  |  | and execute modified versions of a covered work in that User Product from
 | 
					
						
							|  |  |  |  | a modified version of its Corresponding Source.  The information must
 | 
					
						
							|  |  |  |  | suffice to ensure that the continued functioning of the modified object
 | 
					
						
							|  |  |  |  | code is in no case prevented or interfered with solely because
 | 
					
						
							|  |  |  |  | modification has been made.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   If you convey an object code work under this section in, or with, or
 | 
					
						
							|  |  |  |  | specifically for use in, a User Product, and the conveying occurs as
 | 
					
						
							|  |  |  |  | part of a transaction in which the right of possession and use of the
 | 
					
						
							|  |  |  |  | User Product is transferred to the recipient in perpetuity or for a
 | 
					
						
							|  |  |  |  | fixed term (regardless of how the transaction is characterized), the
 | 
					
						
							|  |  |  |  | Corresponding Source conveyed under this section must be accompanied
 | 
					
						
							|  |  |  |  | by the Installation Information.  But this requirement does not apply
 | 
					
						
							|  |  |  |  | if neither you nor any third party retains the ability to install
 | 
					
						
							|  |  |  |  | modified object code on the User Product (for example, the work has
 | 
					
						
							|  |  |  |  | been installed in ROM).
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   The requirement to provide Installation Information does not include a
 | 
					
						
							|  |  |  |  | requirement to continue to provide support service, warranty, or updates
 | 
					
						
							|  |  |  |  | for a work that has been modified or installed by the recipient, or for
 | 
					
						
							|  |  |  |  | the User Product in which it has been modified or installed.  Access to a
 | 
					
						
							|  |  |  |  | network may be denied when the modification itself materially and
 | 
					
						
							|  |  |  |  | adversely affects the operation of the network or violates the rules and
 | 
					
						
							|  |  |  |  | protocols for communication across the network.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Corresponding Source conveyed, and Installation Information provided,
 | 
					
						
							|  |  |  |  | in accord with this section must be in a format that is publicly
 | 
					
						
							|  |  |  |  | documented (and with an implementation available to the public in
 | 
					
						
							|  |  |  |  | source code form), and must require no special password or key for
 | 
					
						
							|  |  |  |  | unpacking, reading or copying.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   7. Additional Terms.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   "Additional permissions" are terms that supplement the terms of this
 | 
					
						
							|  |  |  |  | License by making exceptions from one or more of its conditions.
 | 
					
						
							|  |  |  |  | Additional permissions that are applicable to the entire Program shall
 | 
					
						
							|  |  |  |  | be treated as though they were included in this License, to the extent
 | 
					
						
							|  |  |  |  | that they are valid under applicable law.  If additional permissions
 | 
					
						
							|  |  |  |  | apply only to part of the Program, that part may be used separately
 | 
					
						
							|  |  |  |  | under those permissions, but the entire Program remains governed by
 | 
					
						
							|  |  |  |  | this License without regard to the additional permissions.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   When you convey a copy of a covered work, you may at your option
 | 
					
						
							|  |  |  |  | remove any additional permissions from that copy, or from any part of
 | 
					
						
							|  |  |  |  | it.  (Additional permissions may be written to require their own
 | 
					
						
							|  |  |  |  | removal in certain cases when you modify the work.)  You may place
 | 
					
						
							|  |  |  |  | additional permissions on material, added by you to a covered work,
 | 
					
						
							|  |  |  |  | for which you have or can give appropriate copyright permission.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Notwithstanding any other provision of this License, for material you
 | 
					
						
							|  |  |  |  | add to a covered work, you may (if authorized by the copyright holders of
 | 
					
						
							|  |  |  |  | that material) supplement the terms of this License with terms:
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     a) Disclaiming warranty or limiting liability differently from the
 | 
					
						
							|  |  |  |  |     terms of sections 15 and 16 of this License; or
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     b) Requiring preservation of specified reasonable legal notices or
 | 
					
						
							|  |  |  |  |     author attributions in that material or in the Appropriate Legal
 | 
					
						
							|  |  |  |  |     Notices displayed by works containing it; or
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     c) Prohibiting misrepresentation of the origin of that material, or
 | 
					
						
							|  |  |  |  |     requiring that modified versions of such material be marked in
 | 
					
						
							|  |  |  |  |     reasonable ways as different from the original version; or
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     d) Limiting the use for publicity purposes of names of licensors or
 | 
					
						
							|  |  |  |  |     authors of the material; or
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     e) Declining to grant rights under trademark law for use of some
 | 
					
						
							|  |  |  |  |     trade names, trademarks, or service marks; or
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     f) Requiring indemnification of licensors and authors of that
 | 
					
						
							|  |  |  |  |     material by anyone who conveys the material (or modified versions of
 | 
					
						
							|  |  |  |  |     it) with contractual assumptions of liability to the recipient, for
 | 
					
						
							|  |  |  |  |     any liability that these contractual assumptions directly impose on
 | 
					
						
							|  |  |  |  |     those licensors and authors.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   All other non-permissive additional terms are considered "further
 | 
					
						
							|  |  |  |  | restrictions" within the meaning of section 10.  If the Program as you
 | 
					
						
							|  |  |  |  | received it, or any part of it, contains a notice stating that it is
 | 
					
						
							|  |  |  |  | governed by this License along with a term that is a further
 | 
					
						
							|  |  |  |  | restriction, you may remove that term.  If a license document contains
 | 
					
						
							|  |  |  |  | a further restriction but permits relicensing or conveying under this
 | 
					
						
							|  |  |  |  | License, you may add to a covered work material governed by the terms
 | 
					
						
							|  |  |  |  | of that license document, provided that the further restriction does
 | 
					
						
							|  |  |  |  | not survive such relicensing or conveying.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   If you add terms to a covered work in accord with this section, you
 | 
					
						
							|  |  |  |  | must place, in the relevant source files, a statement of the
 | 
					
						
							|  |  |  |  | additional terms that apply to those files, or a notice indicating
 | 
					
						
							|  |  |  |  | where to find the applicable terms.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Additional terms, permissive or non-permissive, may be stated in the
 | 
					
						
							|  |  |  |  | form of a separately written license, or stated as exceptions;
 | 
					
						
							|  |  |  |  | the above requirements apply either way.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   8. Termination.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   You may not propagate or modify a covered work except as expressly
 | 
					
						
							|  |  |  |  | provided under this License.  Any attempt otherwise to propagate or
 | 
					
						
							|  |  |  |  | modify it is void, and will automatically terminate your rights under
 | 
					
						
							|  |  |  |  | this License (including any patent licenses granted under the third
 | 
					
						
							|  |  |  |  | paragraph of section 11).
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   However, if you cease all violation of this License, then your
 | 
					
						
							|  |  |  |  | license from a particular copyright holder is reinstated (a)
 | 
					
						
							|  |  |  |  | provisionally, unless and until the copyright holder explicitly and
 | 
					
						
							|  |  |  |  | finally terminates your license, and (b) permanently, if the copyright
 | 
					
						
							|  |  |  |  | holder fails to notify you of the violation by some reasonable means
 | 
					
						
							|  |  |  |  | prior to 60 days after the cessation.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Moreover, your license from a particular copyright holder is
 | 
					
						
							|  |  |  |  | reinstated permanently if the copyright holder notifies you of the
 | 
					
						
							|  |  |  |  | violation by some reasonable means, this is the first time you have
 | 
					
						
							|  |  |  |  | received notice of violation of this License (for any work) from that
 | 
					
						
							|  |  |  |  | copyright holder, and you cure the violation prior to 30 days after
 | 
					
						
							|  |  |  |  | your receipt of the notice.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Termination of your rights under this section does not terminate the
 | 
					
						
							|  |  |  |  | licenses of parties who have received copies or rights from you under
 | 
					
						
							|  |  |  |  | this License.  If your rights have been terminated and not permanently
 | 
					
						
							|  |  |  |  | reinstated, you do not qualify to receive new licenses for the same
 | 
					
						
							|  |  |  |  | material under section 10.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   9. Acceptance Not Required for Having Copies.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   You are not required to accept this License in order to receive or
 | 
					
						
							|  |  |  |  | run a copy of the Program.  Ancillary propagation of a covered work
 | 
					
						
							|  |  |  |  | occurring solely as a consequence of using peer-to-peer transmission
 | 
					
						
							|  |  |  |  | to receive a copy likewise does not require acceptance.  However,
 | 
					
						
							|  |  |  |  | nothing other than this License grants you permission to propagate or
 | 
					
						
							|  |  |  |  | modify any covered work.  These actions infringe copyright if you do
 | 
					
						
							|  |  |  |  | not accept this License.  Therefore, by modifying or propagating a
 | 
					
						
							|  |  |  |  | covered work, you indicate your acceptance of this License to do so.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   10. Automatic Licensing of Downstream Recipients.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Each time you convey a covered work, the recipient automatically
 | 
					
						
							|  |  |  |  | receives a license from the original licensors, to run, modify and
 | 
					
						
							|  |  |  |  | propagate that work, subject to this License.  You are not responsible
 | 
					
						
							|  |  |  |  | for enforcing compliance by third parties with this License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   An "entity transaction" is a transaction transferring control of an
 | 
					
						
							|  |  |  |  | organization, or substantially all assets of one, or subdividing an
 | 
					
						
							|  |  |  |  | organization, or merging organizations.  If propagation of a covered
 | 
					
						
							|  |  |  |  | work results from an entity transaction, each party to that
 | 
					
						
							|  |  |  |  | transaction who receives a copy of the work also receives whatever
 | 
					
						
							|  |  |  |  | licenses to the work the party's predecessor in interest had or could
 | 
					
						
							|  |  |  |  | give under the previous paragraph, plus a right to possession of the
 | 
					
						
							|  |  |  |  | Corresponding Source of the work from the predecessor in interest, if
 | 
					
						
							|  |  |  |  | the predecessor has it or can get it with reasonable efforts.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   You may not impose any further restrictions on the exercise of the
 | 
					
						
							|  |  |  |  | rights granted or affirmed under this License.  For example, you may
 | 
					
						
							|  |  |  |  | not impose a license fee, royalty, or other charge for exercise of
 | 
					
						
							|  |  |  |  | rights granted under this License, and you may not initiate litigation
 | 
					
						
							|  |  |  |  | (including a cross-claim or counterclaim in a lawsuit) alleging that
 | 
					
						
							|  |  |  |  | any patent claim is infringed by making, using, selling, offering for
 | 
					
						
							|  |  |  |  | sale, or importing the Program or any portion of it.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   11. Patents.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   A "contributor" is a copyright holder who authorizes use under this
 | 
					
						
							|  |  |  |  | License of the Program or a work on which the Program is based.  The
 | 
					
						
							|  |  |  |  | work thus licensed is called the contributor's "contributor version".
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   A contributor's "essential patent claims" are all patent claims
 | 
					
						
							|  |  |  |  | owned or controlled by the contributor, whether already acquired or
 | 
					
						
							|  |  |  |  | hereafter acquired, that would be infringed by some manner, permitted
 | 
					
						
							|  |  |  |  | by this License, of making, using, or selling its contributor version,
 | 
					
						
							|  |  |  |  | but do not include claims that would be infringed only as a
 | 
					
						
							|  |  |  |  | consequence of further modification of the contributor version.  For
 | 
					
						
							|  |  |  |  | purposes of this definition, "control" includes the right to grant
 | 
					
						
							|  |  |  |  | patent sublicenses in a manner consistent with the requirements of
 | 
					
						
							|  |  |  |  | this License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Each contributor grants you a non-exclusive, worldwide, royalty-free
 | 
					
						
							|  |  |  |  | patent license under the contributor's essential patent claims, to
 | 
					
						
							|  |  |  |  | make, use, sell, offer for sale, import and otherwise run, modify and
 | 
					
						
							|  |  |  |  | propagate the contents of its contributor version.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   In the following three paragraphs, a "patent license" is any express
 | 
					
						
							|  |  |  |  | agreement or commitment, however denominated, not to enforce a patent
 | 
					
						
							|  |  |  |  | (such as an express permission to practice a patent or covenant not to
 | 
					
						
							|  |  |  |  | sue for patent infringement).  To "grant" such a patent license to a
 | 
					
						
							|  |  |  |  | party means to make such an agreement or commitment not to enforce a
 | 
					
						
							|  |  |  |  | patent against the party.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   If you convey a covered work, knowingly relying on a patent license,
 | 
					
						
							|  |  |  |  | and the Corresponding Source of the work is not available for anyone
 | 
					
						
							|  |  |  |  | to copy, free of charge and under the terms of this License, through a
 | 
					
						
							|  |  |  |  | publicly available network server or other readily accessible means,
 | 
					
						
							|  |  |  |  | then you must either (1) cause the Corresponding Source to be so
 | 
					
						
							|  |  |  |  | available, or (2) arrange to deprive yourself of the benefit of the
 | 
					
						
							|  |  |  |  | patent license for this particular work, or (3) arrange, in a manner
 | 
					
						
							|  |  |  |  | consistent with the requirements of this License, to extend the patent
 | 
					
						
							|  |  |  |  | license to downstream recipients.  "Knowingly relying" means you have
 | 
					
						
							|  |  |  |  | actual knowledge that, but for the patent license, your conveying the
 | 
					
						
							|  |  |  |  | covered work in a country, or your recipient's use of the covered work
 | 
					
						
							|  |  |  |  | in a country, would infringe one or more identifiable patents in that
 | 
					
						
							|  |  |  |  | country that you have reason to believe are valid.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   If, pursuant to or in connection with a single transaction or
 | 
					
						
							|  |  |  |  | arrangement, you convey, or propagate by procuring conveyance of, a
 | 
					
						
							|  |  |  |  | covered work, and grant a patent license to some of the parties
 | 
					
						
							|  |  |  |  | receiving the covered work authorizing them to use, propagate, modify
 | 
					
						
							|  |  |  |  | or convey a specific copy of the covered work, then the patent license
 | 
					
						
							|  |  |  |  | you grant is automatically extended to all recipients of the covered
 | 
					
						
							|  |  |  |  | work and works based on it.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   A patent license is "discriminatory" if it does not include within
 | 
					
						
							|  |  |  |  | the scope of its coverage, prohibits the exercise of, or is
 | 
					
						
							|  |  |  |  | conditioned on the non-exercise of one or more of the rights that are
 | 
					
						
							|  |  |  |  | specifically granted under this License.  You may not convey a covered
 | 
					
						
							|  |  |  |  | work if you are a party to an arrangement with a third party that is
 | 
					
						
							|  |  |  |  | in the business of distributing software, under which you make payment
 | 
					
						
							|  |  |  |  | to the third party based on the extent of your activity of conveying
 | 
					
						
							|  |  |  |  | the work, and under which the third party grants, to any of the
 | 
					
						
							|  |  |  |  | parties who would receive the covered work from you, a discriminatory
 | 
					
						
							|  |  |  |  | patent license (a) in connection with copies of the covered work
 | 
					
						
							|  |  |  |  | conveyed by you (or copies made from those copies), or (b) primarily
 | 
					
						
							|  |  |  |  | for and in connection with specific products or compilations that
 | 
					
						
							|  |  |  |  | contain the covered work, unless you entered into that arrangement,
 | 
					
						
							|  |  |  |  | or that patent license was granted, prior to 28 March 2007.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Nothing in this License shall be construed as excluding or limiting
 | 
					
						
							|  |  |  |  | any implied license or other defenses to infringement that may
 | 
					
						
							|  |  |  |  | otherwise be available to you under applicable patent law.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   12. No Surrender of Others' Freedom.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   If conditions are imposed on you (whether by court order, agreement or
 | 
					
						
							|  |  |  |  | otherwise) that contradict the conditions of this License, they do not
 | 
					
						
							|  |  |  |  | excuse you from the conditions of this License.  If you cannot convey a
 | 
					
						
							|  |  |  |  | covered work so as to satisfy simultaneously your obligations under this
 | 
					
						
							|  |  |  |  | License and any other pertinent obligations, then as a consequence you may
 | 
					
						
							|  |  |  |  | not convey it at all.  For example, if you agree to terms that obligate you
 | 
					
						
							|  |  |  |  | to collect a royalty for further conveying from those to whom you convey
 | 
					
						
							|  |  |  |  | the Program, the only way you could satisfy both those terms and this
 | 
					
						
							|  |  |  |  | License would be to refrain entirely from conveying the Program.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   13. Use with the GNU Affero General Public License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Notwithstanding any other provision of this License, you have
 | 
					
						
							|  |  |  |  | permission to link or combine any covered work with a work licensed
 | 
					
						
							|  |  |  |  | under version 3 of the GNU Affero General Public License into a single
 | 
					
						
							|  |  |  |  | combined work, and to convey the resulting work.  The terms of this
 | 
					
						
							|  |  |  |  | License will continue to apply to the part which is the covered work,
 | 
					
						
							|  |  |  |  | but the special requirements of the GNU Affero General Public License,
 | 
					
						
							|  |  |  |  | section 13, concerning interaction through a network will apply to the
 | 
					
						
							|  |  |  |  | combination as such.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   14. Revised Versions of this License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   The Free Software Foundation may publish revised and/or new versions of
 | 
					
						
							|  |  |  |  | the GNU General Public License from time to time.  Such new versions will
 | 
					
						
							|  |  |  |  | be similar in spirit to the present version, but may differ in detail to
 | 
					
						
							|  |  |  |  | address new problems or concerns.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Each version is given a distinguishing version number.  If the
 | 
					
						
							|  |  |  |  | Program specifies that a certain numbered version of the GNU General
 | 
					
						
							|  |  |  |  | Public License "or any later version" applies to it, you have the
 | 
					
						
							|  |  |  |  | option of following the terms and conditions either of that numbered
 | 
					
						
							|  |  |  |  | version or of any later version published by the Free Software
 | 
					
						
							|  |  |  |  | Foundation.  If the Program does not specify a version number of the
 | 
					
						
							|  |  |  |  | GNU General Public License, you may choose any version ever published
 | 
					
						
							|  |  |  |  | by the Free Software Foundation.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   If the Program specifies that a proxy can decide which future
 | 
					
						
							|  |  |  |  | versions of the GNU General Public License can be used, that proxy's
 | 
					
						
							|  |  |  |  | public statement of acceptance of a version permanently authorizes you
 | 
					
						
							|  |  |  |  | to choose that version for the Program.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Later license versions may give you additional or different
 | 
					
						
							|  |  |  |  | permissions.  However, no additional obligations are imposed on any
 | 
					
						
							|  |  |  |  | author or copyright holder as a result of your choosing to follow a
 | 
					
						
							|  |  |  |  | later version.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   15. Disclaimer of Warranty.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
 | 
					
						
							|  |  |  |  | APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
 | 
					
						
							|  |  |  |  | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
 | 
					
						
							|  |  |  |  | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
 | 
					
						
							|  |  |  |  | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
 | 
					
						
							|  |  |  |  | PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
 | 
					
						
							|  |  |  |  | IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
 | 
					
						
							|  |  |  |  | ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   16. Limitation of Liability.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 | 
					
						
							|  |  |  |  | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
 | 
					
						
							|  |  |  |  | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
 | 
					
						
							|  |  |  |  | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
 | 
					
						
							|  |  |  |  | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
 | 
					
						
							|  |  |  |  | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
 | 
					
						
							|  |  |  |  | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
 | 
					
						
							|  |  |  |  | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
 | 
					
						
							|  |  |  |  | SUCH DAMAGES.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   17. Interpretation of Sections 15 and 16.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   If the disclaimer of warranty and limitation of liability provided
 | 
					
						
							|  |  |  |  | above cannot be given local legal effect according to their terms,
 | 
					
						
							|  |  |  |  | reviewing courts shall apply local law that most closely approximates
 | 
					
						
							|  |  |  |  | an absolute waiver of all civil liability in connection with the
 | 
					
						
							|  |  |  |  | Program, unless a warranty or assumption of liability accompanies a
 | 
					
						
							|  |  |  |  | copy of the Program in return for a fee.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |                      END OF TERMS AND CONDITIONS
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |             How to Apply These Terms to Your New Programs
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   If you develop a new program, and you want it to be of the greatest
 | 
					
						
							|  |  |  |  | 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 the exclusion of warranty; and each file should have at least
 | 
					
						
							|  |  |  |  | the "copyright" line and a pointer to where the full notice is found.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     <one line to give the program's name and a brief idea of what it does.>
 | 
					
						
							|  |  |  |  |     Copyright (C) <year>  <name of author>
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     This program is free software: you can redistribute it and/or modify
 | 
					
						
							|  |  |  |  |     it under the terms of the GNU General Public License as published by
 | 
					
						
							|  |  |  |  |     the Free Software Foundation, either version 3 of the License, or
 | 
					
						
							|  |  |  |  |     (at your option) any later version.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     This program is distributed in the hope that it will be useful,
 | 
					
						
							|  |  |  |  |     but WITHOUT ANY WARRANTY; without even the implied warranty of
 | 
					
						
							|  |  |  |  |     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
 | 
					
						
							|  |  |  |  |     GNU General Public License for more details.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     You should have received a copy of the GNU General Public License
 | 
					
						
							|  |  |  |  |     along with this program.  If not, see <https://www.gnu.org/licenses/>.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | Also add information on how to contact you by electronic and paper mail.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   If the program does terminal interaction, make it output a short
 | 
					
						
							|  |  |  |  | notice like this when it starts in an interactive mode:
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     <program>  Copyright (C) <year>  <name of author>
 | 
					
						
							|  |  |  |  |     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
 | 
					
						
							|  |  |  |  |     This is free software, and you are welcome to redistribute it
 | 
					
						
							|  |  |  |  |     under certain conditions; type `show c' for details.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | The hypothetical commands `show w' and `show c' should show the appropriate
 | 
					
						
							|  |  |  |  | parts of the General Public License.  Of course, your program's commands
 | 
					
						
							|  |  |  |  | might be different; for a GUI interface, you would use an "about box".
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   You should also get your employer (if you work as a programmer) or school,
 | 
					
						
							|  |  |  |  | if any, to sign a "copyright disclaimer" for the program, if necessary.

							|  |  |  |  |   The GNU General Public License does not permit incorporating your program
 |

 | 
					
						
							|  |  |  |  | may consider it more useful to permit linking proprietary applications with

 | 
					
						
							|  |  |  |  |       and distribution as defined by Sections 1 through 9 of this document.
 | 
					
						
							|  |  |  |  |

 | 
					
						
							|  |  |  |  |       "control" means (i) the power, direct or indirect, to cause the
 | 
					
						
							|  |  |  |  |       direction or management of such entity, whether by contract or

							|  |  |  |  |       otherwise, or (ii) ownership of fifty percent (50%) or more of the
 | 
					
						
							|  |  |  |  |       outstanding shares, or (iii) beneficial ownership of such entity.

							|  |  |  |  |       including but not limited to software source code, documentation
 | 
					
						
							|  |  |  |  |       source, and configuration files.

							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |       "Object" form shall mean any form resulting from mechanical

 | 
					
						
							|  |  |  |  |       not limited to compiled object code, generated documentation,
 | 
					
						
							|  |  |  |  |       and conversions to other media types.

							|  |  |  |  |       copyright notice that is included in or attached to the work
 | 
					
						
							|  |  |  |  |       (an example is provided in the Appendix below).
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |       "Derivative Works" shall mean any work, whether in Source or Object

 | 
					
						
							|  |  |  |  |       represent, as a whole, an original work of authorship. For the purposes
 | 
					
						
							|  |  |  |  |       of this License, Derivative Works shall not include works that remain
 | 
					
						
							|  |  |  |  |       separable from, or merely link (or bind by name) to the interfaces of,
 | 
					
						
							|  |  |  |  |       the Work and Derivative Works thereof.

 | 
					
						
							|  |  |  |  |       submitted to Licensor for inclusion in the Work by the copyright owner
 | 
					
						
							|  |  |  |  |       or by an individual or Legal Entity authorized to submit on behalf of
 | 
					
						
							|  |  |  |  |       the copyright owner. For the purposes of this definition, "submitted"
 | 
					
						
							|  |  |  |  |       means any form of electronic, verbal, or written communication sent
 |

 | 
					
						
							|  |  |  |  |       Licensor for the purpose of discussing and improving the Work, but
 | 
					
						
							|  |  |  |  |       excluding communication that is conspicuously marked or otherwise
 | 
					
						
							|  |  |  |  |       designated in writing by the copyright owner as "Not a Contribution."
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |       "Contributor" shall mean Licensor and any individual or Legal Entity
 | 
					
						
							|  |  |  |  |       on behalf of whom a Contribution has been received by Licensor and
 | 
					
						
							|  |  |  |  |       subsequently incorporated within the Work.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |    2. Grant of Copyright License. Subject to the terms and conditions of
 | 
					
						
							|  |  |  |  |       this License, each Contributor hereby grants to You a perpetual,
 | 
					
						
							|  |  |  |  |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 | 
					
						
							|  |  |  |  |       copyright license to reproduce, prepare Derivative Works of,
 | 
					
						
							|  |  |  |  |       publicly display, publicly perform, sublicense, and distribute the
 | 
					
						
							|  |  |  |  |       Work and such Derivative Works in Source or Object form.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |    3. Grant of Patent License. Subject to the terms and conditions of
 | 
					
						
							|  |  |  |  |       this License, each Contributor hereby grants to You a perpetual,
 | 
					
						
							|  |  |  |  |       worldwide, non-exclusive, no-charge, royalty-free, irrevocable
 | 
					
						
							|  |  |  |  |       (except as stated in this section) patent license to make, have made,
 | 
					
						
							|  |  |  |  |       use, offer to sell, sell, import, and otherwise transfer the Work,
 | 
					
						
							|  |  |  |  |       where such license applies only to those patent claims licensable
 | 
					
						
							|  |  |  |  |       by such Contributor that are necessarily infringed by their
 | 
					
						
							|  |  |  |  |       Contribution(s) alone or by combination of their Contribution(s)
 | 
					
						
							|  |  |  |  |       with the Work to which such Contribution(s) was submitted. If You
 | 
					
						
							|  |  |  |  |       institute patent litigation against any entity (including a
 | 
					
						
							|  |  |  |  |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 | 
					
						
							|  |  |  |  |       or a Contribution incorporated within the Work constitutes direct
 | 
					
						
							|  |  |  |  |       or contributory patent infringement, then any patent licenses
 | 
					
						
							|  |  |  |  |       granted to You under this License for that Work shall terminate
 | 
					
						
							|  |  |  |  |       as of the date such litigation is filed.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |    4. Redistribution. You may reproduce and distribute copies of the
 | 
					
						
							|  |  |  |  |       Work or Derivative Works thereof in any medium, with or without
 | 
					
						
							|  |  |  |  |       modifications, and in Source or Object form, provided that You
 | 
					
						
							|  |  |  |  |       meet the following conditions:
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |       (a) You must give any other recipients of the Work or
 | 
					
						
							|  |  |  |  |           Derivative Works a copy of this License; and
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |       (b) You must cause any modified files to carry prominent notices
 | 
					
						
							|  |  |  |  |           stating that You changed the files; and
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |       (c) You must retain, in the Source form of any Derivative Works
 | 
					
						
							|  |  |  |  |           that You distribute, all copyright, patent, trademark, and
 | 
					
						
							|  |  |  |  |           attribution notices from the Source form of the Work,
 | 
					
						
							|  |  |  |  |           excluding those notices that do not pertain to any part of
 | 
					
						
							|  |  |  |  |           the Derivative Works; and
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |       (d) If the Work includes a "NOTICE" text file as part of its
 | 
					
						
							|  |  |  |  |           distribution, then any Derivative Works that You distribute must
 | 
					
						
							|  |  |  |  |           include a readable copy of the attribution notices contained
 | 
					
						
							|  |  |  |  |           within such NOTICE file, excluding those notices that do not
 | 
					
						
							|  |  |  |  |           pertain to any part of the Derivative Works, in at least one
 | 
					
						
							|  |  |  |  |           of the following places: within a NOTICE text file distributed
 | 
					
						
							|  |  |  |  |           as part of the Derivative Works; within the Source form or
 | 
					
						
							|  |  |  |  |           documentation, if provided along with the Derivative Works; or,
 | 
					
						
							|  |  |  |  |           within a display generated by the Derivative Works, if and
 | 
					
						
							|  |  |  |  |           wherever such third-party notices normally appear. The contents
 | 
					
						
							|  |  |  |  |           of the NOTICE file are for informational purposes only and
 | 
					
						
							|  |  |  |  |           do not modify the License. You may add Your own attribution
 | 
					
						
							|  |  |  |  |           notices within Derivative Works that You distribute, alongside
 | 
					
						
							|  |  |  |  |           or as an addendum to the NOTICE text from the Work, provided
 | 
					
						
							|  |  |  |  |           that such additional attribution notices cannot be construed
 | 
					
						
							|  |  |  |  |           as modifying the License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |       You may add Your own copyright statement to Your modifications and
 | 
					
						
							|  |  |  |  |       may provide additional or different license terms and conditions
 | 
					
						
							|  |  |  |  |       for use, reproduction, or distribution of Your modifications, or
 | 
					
						
							|  |  |  |  |       for any such Derivative Works as a whole, provided Your use,
 | 
					
						
							|  |  |  |  |       reproduction, and distribution of the Work otherwise complies with
 | 
					
						
							|  |  |  |  |       the conditions stated in this License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |    5. Submission of Contributions. Unless You explicitly state otherwise,
 | 
					
						
							|  |  |  |  |       any Contribution intentionally submitted for inclusion in the Work
 | 
					
						
							|  |  |  |  |       by You to the Licensor shall be under the terms and conditions of
 | 
					
						
							|  |  |  |  |       this License, without any additional terms or conditions.
 | 
					
						
							|  |  |  |  |       Notwithstanding the above, nothing herein shall supersede or modify
 | 
					
						
							|  |  |  |  |       the terms of any separate license agreement you may have executed
 | 
					
						
							|  |  |  |  |       with Licensor regarding such Contributions.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |    6. Trademarks. This License does not grant permission to use the trade
 | 
					
						
							|  |  |  |  |       names, trademarks, service marks, or product names of the Licensor,
 | 
					
						
							|  |  |  |  |       except as required for reasonable and customary use in describing the
 | 
					
						
							|  |  |  |  |       origin of the Work and reproducing the content of the NOTICE file.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |    7. Disclaimer of Warranty. Unless required by applicable law or
 | 
					
						
							|  |  |  |  |       agreed to in writing, Licensor provides the Work (and each
 | 
					
						
							|  |  |  |  |       Contributor provides its Contributions) on an "AS IS" BASIS,
 | 
					
						
							|  |  |  |  |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
 | 
					
						
							|  |  |  |  |       implied, including, without limitation, any warranties or conditions
 | 
					
						
							|  |  |  |  |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
 | 
					
						
							|  |  |  |  |       PARTICULAR PURPOSE. You are solely responsible for determining the
 | 
					
						
							|  |  |  |  |       appropriateness of using or redistributing the Work and assume any
 | 
					
						
							|  |  |  |  |       risks associated with Your exercise of permissions under this License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |    8. Limitation of Liability. In no event and under no legal theory,
 | 
					
						
							|  |  |  |  |       whether in tort (including negligence), contract, or otherwise,
 | 
					
						
							|  |  |  |  |       unless required by applicable law (such as deliberate and grossly
 | 
					
						
							|  |  |  |  |       negligent acts) or agreed to in writing, shall any Contributor be
 | 
					
						
							|  |  |  |  |       liable to You for damages, including any direct, indirect, special,
 | 
					
						
							|  |  |  |  |       incidental, or consequential damages of any character arising as a
 | 
					
						
							|  |  |  |  |       result of this License or out of the use or inability to use the
 | 
					
						
							|  |  |  |  |       Work (including but not limited to damages for loss of goodwill,
 | 
					
						
							|  |  |  |  |       work stoppage, computer failure or malfunction, or any and all
 | 
					
						
							|  |  |  |  |       other commercial damages or losses), even if such Contributor
 | 
					
						
							|  |  |  |  |       has been advised of the possibility of such damages.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |    9. Accepting Warranty or Additional Liability. While redistributing
 | 
					
						
							|  |  |  |  |       the Work or Derivative Works thereof, You may choose to offer,
 | 
					
						
							|  |  |  |  |       and charge a fee for, acceptance of support, warranty, indemnity,
 | 
					
						
							|  |  |  |  |       or other liability obligations and/or rights consistent with this
 | 
					
						
							|  |  |  |  |       License. However, in accepting such obligations, You may act only
 | 
					
						
							|  |  |  |  |       on Your own behalf and on Your sole responsibility, not on behalf
 | 
					
						
							|  |  |  |  |       of any other Contributor, and only if You agree to indemnify,
 | 
					
						
							|  |  |  |  |       defend, and hold each Contributor harmless for any liability
 | 
					
						
							|  |  |  |  |       incurred by, or claims asserted against, such Contributor by reason
 | 
					
						
							|  |  |  |  |       of your accepting any such warranty or additional liability.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |    END OF TERMS AND CONDITIONS

 | 
					
						
							|  |  |  |  |       replaced with your own identifying information. (Don't include
 | 
					
						
							|  |  |  |  |       the brackets!)  The text should be enclosed in the appropriate
 | 
					
						
							|  |  |  |  |       comment syntax for the file format. We also recommend that a

							|  |  |  |  |       file or class name and description of purpose be included on the
 | 
					
						
							|  |  |  |  |       same "printed page" as the copyright notice for easier

 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 			    Preamble
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   The licenses for most software are designed to take away your
 | 
					
						
							|  |  |  |  | freedom to share and change it.  By contrast, the GNU General Public
 | 
					
						
							|  |  |  |  | License is intended to guarantee your freedom to share and change free
 | 
					
						
							|  |  |  |  | software--to make sure the software is free for all its users.  This
 | 
					
						
							|  |  |  |  | General Public License applies to most of the Free Software
 | 
					
						
							|  |  |  |  | Foundation's software and to any other program whose authors commit to
 | 
					
						
							|  |  |  |  | using it.  (Some other Free Software Foundation software is covered by
 | 
					
						
							|  |  |  |  | the GNU Library General Public License instead.)  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
 | 
					
						
							|  |  |  |  | this service 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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   To protect your rights, we need to make restrictions that forbid
 | 
					
						
							|  |  |  |  | anyone to deny you these rights or to ask you to surrender the rights.
 | 
					
						
							|  |  |  |  | These restrictions translate to certain responsibilities for you if you
 | 
					
						
							|  |  |  |  | distribute copies of the software, or if you modify it.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   For example, if you distribute copies of such a program, whether
 | 
					
						
							|  |  |  |  | gratis or for a fee, you must give the recipients all the rights that
 | 
					
						
							|  |  |  |  | you have.  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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   We protect your rights with two steps: (1) copyright the software, and
 | 
					
						
							|  |  |  |  | (2) offer you this license which gives you legal permission to copy,
 | 
					
						
							|  |  |  |  | distribute and/or modify the software.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Also, for each author's protection and ours, we want to make certain
 | 
					
						
							|  |  |  |  | that everyone understands that there is no warranty for this free
 | 
					
						
							|  |  |  |  | software.  If the software is modified by someone else and passed on, we
 | 
					
						
							|  |  |  |  | want its recipients to know that what they have is not the original, so
 | 
					
						
							|  |  |  |  | that any problems introduced by others will not reflect on the original
 | 
					
						
							|  |  |  |  | authors' reputations.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   Finally, any free program is threatened constantly by software
 | 
					
						
							|  |  |  |  | patents.  We wish to avoid the danger that redistributors of a free
 | 
					
						
							|  |  |  |  | program will individually obtain patent licenses, in effect making the
 | 
					
						
							|  |  |  |  | program proprietary.  To prevent this, we have made it clear that any
 | 
					
						
							|  |  |  |  | patent must be licensed for everyone's free use or not licensed at all.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   The precise terms and conditions for copying, distribution and
 | 
					
						
							|  |  |  |  | modification follow.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 		    GNU GENERAL PUBLIC LICENSE
 | 
					
						
							|  |  |  |  |    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   0. 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".
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   1. 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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 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.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   2. 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:
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     a) You must cause the modified files to carry prominent notices
 | 
					
						
							|  |  |  |  |     stating that you changed the files and the date of any change.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     b) You must cause any work that you distribute or publish, that in
 | 
					
						
							|  |  |  |  |     whole or in part contains or is derived from the Program or any
 | 
					
						
							|  |  |  |  |     part thereof, to be licensed as a whole at no charge to all third
 | 
					
						
							|  |  |  |  |     parties under the terms of this License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     c) If the modified program normally reads commands interactively
 | 
					
						
							|  |  |  |  |     when run, you must cause it, when started running for such
 | 
					
						
							|  |  |  |  |     interactive use in the most ordinary way, to print or display an
 | 
					
						
							|  |  |  |  |     announcement including an appropriate copyright notice and a
 | 
					
						
							|  |  |  |  |     notice that there is no warranty (or else, saying that you provide
 | 
					
						
							|  |  |  |  |     a warranty) and that users may redistribute the program under
 | 
					
						
							|  |  |  |  |     these conditions, and telling the user how to view a copy of this
 | 
					
						
							|  |  |  |  |     License.  (Exception: if the Program itself is interactive but
 | 
					
						
							|  |  |  |  |     does not normally print such an announcement, your work based on
 | 
					
						
							|  |  |  |  |     the Program is not required to print an announcement.)
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | These requirements apply to the modified work as a whole.  If
 | 
					
						
							|  |  |  |  | identifiable sections of that work are not derived from the Program,
 | 
					
						
							|  |  |  |  | and can be reasonably considered independent and separate works in
 | 
					
						
							|  |  |  |  | themselves, then this License, and its terms, do not apply to those
 | 
					
						
							|  |  |  |  | sections when you distribute them as separate works.  But when you
 | 
					
						
							|  |  |  |  | distribute the same sections as part of a whole which is a work based
 | 
					
						
							|  |  |  |  | on the Program, the distribution of the whole must be on the terms of
 | 
					
						
							|  |  |  |  | this License, whose permissions for other licensees extend to the
 | 
					
						
							|  |  |  |  | entire whole, and thus to each and every part regardless of who wrote it.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | Thus, it is not the intent of this section to claim rights or contest
 | 
					
						
							|  |  |  |  | your rights to work written entirely by you; rather, the intent is to
 | 
					
						
							|  |  |  |  | exercise the right to control the distribution of derivative or
 | 
					
						
							|  |  |  |  | collective works based on the Program.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | In addition, mere aggregation of another work not based on the Program
 | 
					
						
							|  |  |  |  | with the Program (or with a work based on the Program) on a volume of
 | 
					
						
							|  |  |  |  | a storage or distribution medium does not bring the other work under
 | 
					
						
							|  |  |  |  | the scope of this License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   3. You may copy and distribute the Program (or a work based on it,
 | 
					
						
							|  |  |  |  | under Section 2) in object code or executable form under the terms of
 | 
					
						
							|  |  |  |  | Sections 1 and 2 above provided that you also do one of the following:
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     a) Accompany it with the complete corresponding machine-readable
 | 
					
						
							|  |  |  |  |     source code, which must be distributed under the terms of Sections
 | 
					
						
							|  |  |  |  |     1 and 2 above on a medium customarily used for software interchange; or,
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     b) Accompany it with a written offer, valid for at least three
 | 
					
						
							|  |  |  |  |     years, to give any third party, for a charge no more than your
 | 
					
						
							|  |  |  |  |     cost of physically performing source distribution, a complete
 | 
					
						
							|  |  |  |  |     machine-readable copy of the corresponding source code, to be
 | 
					
						
							|  |  |  |  |     distributed under the terms of Sections 1 and 2 above on a medium
 | 
					
						
							|  |  |  |  |     customarily used for software interchange; or,
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     c) Accompany it with the information you received as to the offer
 | 
					
						
							|  |  |  |  |     to distribute corresponding source code.  (This alternative is
 | 
					
						
							|  |  |  |  |     allowed only for noncommercial distribution and only if you
 | 
					
						
							|  |  |  |  |     received the program in object code or executable form with such
 | 
					
						
							|  |  |  |  |     an offer, in accord with Subsection b above.)
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | The source code for a work means the preferred form of the work for
 | 
					
						
							|  |  |  |  | making modifications to it.  For an executable work, complete source
 | 
					
						
							|  |  |  |  | code means all the source code for all modules it contains, plus any
 | 
					
						
							|  |  |  |  | associated interface definition files, plus the scripts used to
 | 
					
						
							|  |  |  |  | control compilation and installation of the executable.  However, as a
 | 
					
						
							|  |  |  |  | special exception, the source code distributed need not include
 | 
					
						
							|  |  |  |  | anything that is normally distributed (in either source or binary
 | 
					
						
							|  |  |  |  | form) with the major components (compiler, kernel, and so on) of the
 | 
					
						
							|  |  |  |  | operating system on which the executable runs, unless that component
 | 
					
						
							|  |  |  |  | itself accompanies the executable.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | If distribution of executable or object code is made by offering
 | 
					
						
							|  |  |  |  | access to copy from a designated place, then offering equivalent
 | 
					
						
							|  |  |  |  | access to copy the source code from the same place counts as
 | 
					
						
							|  |  |  |  | distribution of the source code, even though third parties are not
 | 
					
						
							|  |  |  |  | compelled to copy the source along with the object code.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   4. You may not copy, modify, sublicense, or distribute the Program
 | 
					
						
							|  |  |  |  | except as expressly provided under this License.  Any attempt
 | 
					
						
							|  |  |  |  | otherwise to copy, modify, sublicense or distribute the Program is
 | 
					
						
							|  |  |  |  | void, and will automatically terminate your rights under this License.
 | 
					
						
							|  |  |  |  | However, parties who have received copies, or rights, from you under
 | 
					
						
							|  |  |  |  | this License will not have their licenses terminated so long as such
 | 
					
						
							|  |  |  |  | parties remain in full compliance.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   5. You are not required to accept this License, since you have not
 | 
					
						
							|  |  |  |  | signed it.  However, nothing else grants you permission to modify or
 | 
					
						
							|  |  |  |  | distribute the Program or its derivative works.  These actions are
 | 
					
						
							|  |  |  |  | prohibited by law if you do not accept this License.  Therefore, by
 | 
					
						
							|  |  |  |  | modifying or distributing the Program (or any work based on the
 | 
					
						
							|  |  |  |  | Program), you indicate your acceptance of this License to do so, and
 | 
					
						
							|  |  |  |  | all its terms and conditions for copying, distributing or modifying
 | 
					
						
							|  |  |  |  | the Program or works based on it.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   6. Each time you redistribute the Program (or any work based on the
 | 
					
						
							|  |  |  |  | Program), the recipient automatically receives a license from the
 | 
					
						
							|  |  |  |  | original licensor to copy, distribute or modify the Program subject to
 | 
					
						
							|  |  |  |  | these terms and conditions.  You may not impose any further
 | 
					
						
							|  |  |  |  | restrictions on the recipients' exercise of the rights granted herein.
 | 
					
						
							|  |  |  |  | You are not responsible for enforcing compliance by third parties to
 | 
					
						
							|  |  |  |  | this License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   7. If, as a consequence of a court judgment or allegation of patent
 | 
					
						
							|  |  |  |  | infringement or for any other reason (not limited to patent issues),
 | 
					
						
							|  |  |  |  | conditions are imposed on you (whether by court order, agreement or
 | 
					
						
							|  |  |  |  | otherwise) that contradict the conditions of this License, they do not
 | 
					
						
							|  |  |  |  | excuse you from the conditions of this License.  If you cannot
 | 
					
						
							|  |  |  |  | distribute so as to satisfy simultaneously your obligations under this
 | 
					
						
							|  |  |  |  | License and any other pertinent obligations, then as a consequence you
 | 
					
						
							|  |  |  |  | may not distribute the Program at all.  For example, if a patent
 | 
					
						
							|  |  |  |  | license would not permit royalty-free redistribution of the Program by
 | 
					
						
							|  |  |  |  | all those who receive copies directly or indirectly through you, then
 | 
					
						
							|  |  |  |  | the only way you could satisfy both it and this License would be to
 | 
					
						
							|  |  |  |  | refrain entirely from distribution of the Program.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | If any portion of this section is held invalid or unenforceable under
 | 
					
						
							|  |  |  |  | any particular circumstance, the balance of the section is intended to
 | 
					
						
							|  |  |  |  | apply and the section as a whole is intended to apply in other
 | 
					
						
							|  |  |  |  | circumstances.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | It is not the purpose of this section to induce you to infringe any
 | 
					
						
							|  |  |  |  | patents or other property right claims or to contest validity of any
 | 
					
						
							|  |  |  |  | such claims; this section has the sole purpose of protecting the
 | 
					
						
							|  |  |  |  | integrity of the free software distribution system, which is
 | 
					
						
							|  |  |  |  | implemented by public license practices.  Many people have made
 | 
					
						
							|  |  |  |  | generous contributions to the wide range of software distributed
 | 
					
						
							|  |  |  |  | through that system in reliance on consistent application of that
 | 
					
						
							|  |  |  |  | system; it is up to the author/donor to decide if he or she is willing
 | 
					
						
							|  |  |  |  | to distribute software through any other system and a licensee cannot
 | 
					
						
							|  |  |  |  | impose that choice.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | This section is intended to make thoroughly clear what is believed to
 | 
					
						
							|  |  |  |  | be a consequence of the rest of this License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   8. If the distribution and/or use of the Program is restricted in
 | 
					
						
							|  |  |  |  | certain countries either by patents or by copyrighted interfaces, the
 | 
					
						
							|  |  |  |  | original copyright holder who places the Program under this License
 | 
					
						
							|  |  |  |  | may add an explicit geographical distribution limitation excluding
 | 
					
						
							|  |  |  |  | those countries, so that distribution is permitted only in or among
 | 
					
						
							|  |  |  |  | countries not thus excluded.  In such case, this License incorporates
 | 
					
						
							|  |  |  |  | the limitation as if written in the body of this License.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   9. The Free Software Foundation may publish revised and/or new versions
 | 
					
						
							|  |  |  |  | of the General Public License from time to time.  Such new versions will
 | 
					
						
							|  |  |  |  | be similar in spirit to the present version, but may differ in detail to
 | 
					
						
							|  |  |  |  | address new problems or concerns.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | Each version is given a distinguishing version number.  If the Program
 | 
					
						
							|  |  |  |  | specifies a version number of this License which applies to it and "any
 | 
					
						
							|  |  |  |  | later version", you have the option of following the terms and conditions
 | 
					
						
							|  |  |  |  | either of that version or of any later version published by the Free
 | 
					
						
							|  |  |  |  | Software Foundation.  If the Program does not specify a version number of
 | 
					
						
							|  |  |  |  | this License, you may choose any version ever published by the Free Software
 | 
					
						
							|  |  |  |  | Foundation.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   10. If you wish to incorporate parts of the Program into other free
 | 
					
						
							|  |  |  |  | programs whose distribution conditions are different, write to the author
 | 
					
						
							|  |  |  |  | to ask for permission.  For software which is copyrighted by the Free
 | 
					
						
							|  |  |  |  | Software Foundation, write to the Free Software Foundation; we sometimes
 | 
					
						
							|  |  |  |  | make exceptions for this.  Our decision will be guided by the two goals
 | 
					
						
							|  |  |  |  | of preserving the free status of all derivatives of our free software and
 | 
					
						
							|  |  |  |  | of promoting the sharing and reuse of software generally.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 			    NO WARRANTY
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 | 
					
						
							|  |  |  |  | FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
 | 
					
						
							|  |  |  |  | OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
 | 
					
						
							|  |  |  |  | PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
 | 
					
						
							|  |  |  |  | OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
 | 
					
						
							|  |  |  |  | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
 | 
					
						
							|  |  |  |  | TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
 | 
					
						
							|  |  |  |  | PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
 | 
					
						
							|  |  |  |  | REPAIR OR CORRECTION.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 | 
					
						
							|  |  |  |  | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 | 
					
						
							|  |  |  |  | REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 | 
					
						
							|  |  |  |  | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
 | 
					
						
							|  |  |  |  | OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
 | 
					
						
							|  |  |  |  | TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
 | 
					
						
							|  |  |  |  | YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
 | 
					
						
							|  |  |  |  | PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
 | 
					
						
							|  |  |  |  | POSSIBILITY OF SUCH DAMAGES.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 		     END OF TERMS AND CONDITIONS
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | 	    How to Apply These Terms to Your New Programs
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |   If you develop a new program, and you want it to be of the greatest
 | 
					
						
							|  |  |  |  | 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
 | 
					
						
							|  |  |  |  | convey the exclusion of warranty; and each file should have at least
 | 
					
						
							|  |  |  |  | the "copyright" line and a pointer to where the full notice is found.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  |     <one line to give the program's name and a brief idea of what it does.>

							|  |  |  |  | Also add information on how to contact you by electronic and paper mail.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | If the program is interactive, make it output a short notice like this
 | 
					
						
							|  |  |  |  | when it starts in an interactive mode:

 | 
					
						
							|  |  |  |  |     This is free software, and you are welcome to redistribute it
 | 
					
						
							|  |  |  |  |     under certain conditions; type `show c' for details.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | The hypothetical commands `show w' and `show c' should show the appropriate
 | 
					
						
							|  |  |  |  | parts of the General Public License.  Of course, the commands you use may
 | 
					
						
							|  |  |  |  | be called something other than `show w' and `show c'; they could even be
 | 
					
						
							|  |  |  |  | mouse-clicks or menu items--whatever suits your program.
 | 
					
						
							|  |  |  |  | 
 | 
					
						
							|  |  |  |  | You should also get your employer (if you work as a programmer) or your
 | 
					
						
							|  |  |  |  | school, if any, to sign a "copyright disclaimer" for the program, if
 | 
					
						
							|  |  |  |  | necessary.  Here is a sample; alter the names:
