  GNU General Public License
  Version 3, 29 June 2007
             Copyright (c) 2007 Free Software Foundation, Inc. <>

             Everyone is permitted to copy and distribute verbatim copies of this
             license document, but changing it is not allowed.

     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

     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.

GPL(7)                         GNU                         GPL(7)

     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

     The precise terms and conditions for copying, distribution
     and modification follow.

     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

gcc-7.3.0            Last change: 2018-01-25                    2

GPL(7)                         GNU                         GPL(7)

         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.

gcc-7.3.0            Last change: 2018-01-25                    3

GPL(7)                         GNU                         GPL(7)

         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

         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

         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

         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

gcc-7.3.0            Last change: 2018-01-25                    5

GPL(7)                         GNU                         GPL(7)

             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.

gcc-7.3.0            Last change: 2018-01-25                    6

GPL(7)                         GNU                         GPL(7)

         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.

gcc-7.3.0            Last change: 2018-01-25                    7

GPL(7)                         GNU                         GPL(7)

         "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.

GPL(7)                         GNU                         GPL(7)

         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

gcc-7.3.0            Last change: 2018-01-25                    9

GPL(7)                         GNU                         GPL(7)

         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.

gcc-7.3.0            Last change: 2018-01-25                   10

GPL(7)                         GNU                         GPL(7)

         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.

gcc-7.3.0            Last change: 2018-01-25                   11

GPL(7)                         GNU                         GPL(7)

         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

         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

gcc-7.3.0            Last change: 2018-01-25                   12

GPL(7)                         GNU                         GPL(7)

         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

gcc-7.3.0            Last change: 2018-01-25                   13

GPL(7)                         GNU                         GPL(7)

         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

         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

     15. Disclaimer of Warranty.

     16. Limitation of Liability.

     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

gcc-7.3.0            Last change: 2018-01-25                   14

GPL(7)                         GNU                         GPL(7)

         liability accompanies a copy of the Program in return
         for a fee.

  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
             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 <>.

     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

             <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.  For more

     The GNU General Public License does not permit incorporating
     your program into proprietary programs.  If your program is
     a subroutine library, you may consider it more useful to
     permit linking proprietary applications with the library.
     If this is what you want to do, use the GNU Lesser General
     Public License instead of this License.  But first, please
