+                    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

+

+            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:

+

+    <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

+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+Unter dem Markennamen "SolarMax" vertreibt die schweizer Firma 

+Sputnik Engineering AG Fotovoltaik-Wechselrichter.

+

+Die SolarMax-Wechselrichter lassen sich mit normaler Ethernet-Verbindung 

+abfragen und nutzen dabei ein (gewissermaßen) Text-basiertes Protokoll über

+eine TCP-Verbindung.

+

+Das verwendete Protokoll wurde von mir reverse engineered (mittels 

+Netzwerk-capturing bei Verwendung der MaxTalk-Software).

+

+Erst nach Implementierung der Basisfunktionalität erhielt ich doch

+noch eine Dokumentation des verwendeten Protokolls vom Hersteller.

+Die Lizenz dieser Schnittstellenbeschreibung erlaubt es jedoch nicht, 

+diese öffentlich zu machen:

+| Der Nutzer sieht davon ab, das Datenprotokoll Dritten 

+| gegenüber offenzulegen. Weiter sieht er davon ab, das 

+| MaxComm Datenprotokoll zur serienmässigen Herstellung 

+| von Datenvisualisierungs und –überwachungsgeräten sowie 

+| von Alarmierungsgeräten für Wechselrichteranlagen zu 

+| verwenden, welche die entsprechenden Standardlösungen 

+| des Lieferers konkurrenzieren. Erlaubt ist dagegen die 

+| Verwendung für die Herstellung von derartigen Geräten 

+| für den eigenen Gebrauch oder im Rahmen von massge-

+| schneiderten Datenkommunikations-System-Einzellösungen 

+| für bestimmte Kunden. Im Zweifelsfall ist Sputnik 

+| anzufragen.
