* GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007
*
* Copyright (C) 2007 Free Software Foundation, Inc. <http://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

* 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 <http://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:
*
* {project} Copyright (C) {year} {fullname} 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 information on this, and how to apply and follow the
* GNU GPL, see <http://www.gnu.org/licenses/>.
*
* 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 read
* <http://www.gnu.org/philosophy/why-not-lgpl.html>.
