                     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
 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

     This program is distributed in the hope that it will be useful,
     but WITHOUT ANY WARRANTY; without even the implied warranty of

     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:
 
     <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 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

 That said, portions of linssid make use of libraries which have their
 own licenses written in gloriously arcane legalese.

 Also, linssid is developed based on Qt which is available under the LGPL 2.1
 license:

 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 
 0. This License Agreement applies to any software library or other program which
 contains a notice placed by the copyright holder or other authorized party
 saying it may be distributed under the terms of this Lesser General Public
 License (also called "this License"). Each licensee is addressed as "you".
 
 A "library" means a collection of software functions and/or data prepared so as
 to be conveniently linked with application programs (which use some of those
 functions and data) to form executables.
 
 The "Library", below, refers to any such software library or work which has been
 distributed under these terms. A "work based on the Library" means either the
 Library or any derivative work under copyright law: that is to say, a work
 containing the Library or a portion of it, either verbatim or with modifications
 and/or translated straightforwardly into another language. (Hereinafter,
 translation is included without limitation in the term "modification".)
 
 "Source code" for a work means the preferred form of the work for making
 modifications to it. For a library, 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
 library.
 
 Activities other than copying, distribution and modification are not covered by
 this License; they are outside its scope. The act of running a program using the
 Library is not restricted, and output from such a program is covered only if its
 contents constitute a work based on the Library (independent of the use of the
 Library in a tool for writing it). Whether that is true depends on what the
 Library does and what the program that uses the Library does.
 
 1. You may copy and distribute verbatim copies of the Library's complete 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 distribute a copy of this License along
 with the Library.
 
 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 Library or any portion of it, thus
 forming a work based on the Library, 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) The modified work must itself be a software library.
 
     b) You must cause the files modified to carry prominent notices stating that
 you changed the files and the date of any change.
 
     c) You must cause the whole of the work to be licensed at no charge to all
 third parties under the terms of this License.
 
     d) If a facility in the modified Library refers to a function or a table of
 data to be supplied by an application program that uses the facility, other than
 as an argument passed when the facility is invoked, then you must make a good
 faith effort to ensure that, in the event an application does not supply such
 function or table, the facility still operates, and performs whatever part of
 its purpose remains meaningful.
 
     (For example, a function in a library to compute square roots has a purpose
 that is entirely well-defined independent of the application. Therefore,
 Subsection 2d requires that any application-supplied function or table used by
 this function must be optional: if the application does not supply it, the
 square root function must still compute square roots.)
 
     These requirements apply to the modified work as a whole. If identifiable
 sections of that work are not derived from the Library, 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 Library, 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
 Library.
 
     In addition, mere aggregation of another work not based on the Library with
 the Library (or with a work based on the Library) on a volume of a storage or
 distribution medium does not bring the other work under the scope of this
 License. 
 
 3. You may opt to apply the terms of the ordinary GNU General Public License
 instead of this License to a given copy of the Library. To do this, you must
 alter all the notices that refer to this License, so that they refer to the
 ordinary GNU General Public License, version 2, instead of to this License. (If
 a newer version than version 2 of the ordinary GNU General Public License has
 appeared, then you can specify that version instead if you wish.) Do not make
 any other change in these notices.
 
 Once this change is made in a given copy, it is irreversible for that copy, so
 the ordinary GNU General Public License applies to all subsequent copies and
 derivative works made from that copy.
 
 This option is useful when you wish to copy part of the code of the Library into
 a program that is not a library.
 
 4. You may copy and distribute the Library (or a portion or derivative of it,
 under Section 2) in object code or executable form under the terms of Sections 1
 and 2 above provided that you 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.
 
 If distribution of 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 satisfies the requirement to distribute the source code, even
 though third parties are not compelled to copy the source along with the object
 code.
 
 5. A program that contains no derivative of any portion of the Library, but is
 designed to work with the Library by being compiled or linked with it, is called
 a "work that uses the Library". Such a work, in isolation, is not a derivative
 work of the Library, and therefore falls outside the scope of this License.
 
 However, linking a "work that uses the Library" with the Library creates an
 executable that is a derivative of the Library (because it contains portions of
 the Library), rather than a "work that uses the library". The executable is
 therefore covered by this License. Section 6 states terms for distribution of
 such executables.
 
 When a "work that uses the Library" uses material from a header file that is
 part of the Library, the object code for the work may be a derivative work of
 the Library even though the source code is not. Whether this is true is
 especially significant if the work can be linked without the Library, or if the
 work is itself a library. The threshold for this to be true is not precisely
 defined by law.
 
 If such an object file uses only numerical parameters, data structure layouts
 and accessors, and small macros and small inline functions (ten lines or less in
 length), then the use of the object file is unrestricted, regardless of whether
 it is legally a derivative work. (Executables containing this object code plus
 portions of the Library will still fall under Section 6.)
 
 Otherwise, if the work is a derivative of the Library, you may distribute the
 object code for the work under the terms of Section 6. Any executables
 containing that work also fall under Section 6, whether or not they are linked
 directly with the Library itself.
 
 6. As an exception to the Sections above, you may also combine or link a "work
 that uses the Library" with the Library to produce a work containing portions of
 the Library, and distribute that work under terms of your choice, provided that
 the terms permit modification of the work for the customer's own use and reverse
 engineering for debugging such modifications.
 
 You must give prominent notice with each copy of the work that the Library is
 used in it and that the Library and its use are covered by this License. You
 must supply a copy of this License. If the work during execution displays
 copyright notices, you must include the copyright notice for the Library among
 them, as well as a reference directing the user to the copy of this License.
 Also, you must do one of these things:
 
     a) Accompany the work with the complete corresponding machine-readable
 source code for the Library including whatever changes were used in the work
 (which must be distributed under Sections 1 and 2 above); and, if the work is an
 executable linked with the Library, with the complete machine-readable "work
 that uses the Library", as object code and/or source code, so that the user can
 modify the Library and then relink to produce a modified executable containing
 the modified Library. (It is understood that the user who changes the contents
 of definitions files in the Library will not necessarily be able to recompile
 the application to use the modified definitions.)
 
     b) Use a suitable shared library mechanism for linking with the Library. A
 suitable mechanism is one that (1) uses at run time a copy of the library
 already present on the user's computer system, rather than copying library
 functions into the executable, and (2) will operate properly with a modified
 version of the library, if the user installs one, as long as the modified
 version is interface-compatible with the version that the work was made with.
 
     c) Accompany the work with a written offer, valid for at least three years,
 to give the same user the materials specified in Subsection 6a, above, for a
 charge no more than the cost of performing this distribution.
 
     d) If distribution of the work is made by offering access to copy from a
 designated place, offer equivalent access to copy the above specified materials
 from the same place.
 
     e) Verify that the user has already received a copy of these materials or
 that you have already sent this user a copy.
 
 For an executable, the required form of the "work that uses the Library" must
 include any data and utility programs needed for reproducing the executable from
 it. However, as a special exception, the materials to be 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.
 
 It may happen that this requirement contradicts the license restrictions of
 other proprietary libraries that do not normally accompany the operating system.
 Such a contradiction means you cannot use both them and the Library together in
 an executable that you distribute.
 
 7. You may place library facilities that are a work based on the Library
 side-by-side in a single library together with other library facilities not
 covered by this License, and distribute such a combined library, provided that
 the separate distribution of the work based on the Library and of the other
 library facilities is otherwise permitted, and provided that you do these two
 things:
 
     a) Accompany the combined library with a copy of the same work based on the
 Library, uncombined with any other library facilities. This must be distributed
 under the terms of the Sections above.
 
     b) Give prominent notice with the combined library of the fact that part of
 it is a work based on the Library, and explaining where to find the accompanying
 uncombined form of the same work.
 
 8. You may not copy, modify, sublicense, link with, or distribute the Library
 except as expressly provided under this License. Any attempt otherwise to copy,
 modify, sublicense, link with, or distribute the Library 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.
 
 9. 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 Library
 or its derivative works. These actions are prohibited by law if you do not
 accept this License. Therefore, by modifying or distributing the Library (or any
 work based on the Library), you indicate your acceptance of this License to do
 so, and all its terms and conditions for copying, distributing or modifying the
 Library or works based on it.
 
 10. Each time you redistribute the Library (or any work based on the Library),
 the recipient automatically receives a license from the original licensor to
 copy, distribute, link with or modify the Library 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 with this License.
 
 11. 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 Library at all.
 For example, if a patent license would not permit royalty-free redistribution of
 the Library 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 Library.
 
 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.
 
 12. If the distribution and/or use of the Library is restricted in certain
 countries either by patents or by copyrighted interfaces, the original copyright
 holder who places the Library 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.
 
 13. The Free Software Foundation may publish revised and/or new versions of the
 Lesser 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 Library 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
 Library does not specify a license version number, you may choose any version
 ever published by the Free Software Foundation.
 
 14. If you wish to incorporate parts of the Library into other free programs
 whose distribution conditions are incompatible with these, 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
 
 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE
 LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED
 IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "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
 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF
 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 
 16. 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
 LIBRARY 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 LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER
 PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
