  1 + GNU GENERAL PUBLIC LICENSE
  2 + Version 3, 29 June 2007
  3 +
  4 + Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
  5 + Everyone is permitted to copy and distribute verbatim copies
  6 + of this license document, but changing it is not allowed.
  7 +
  8 + Preamble
  9 +
  10 + The GNU General Public License is a free, copyleft license for
  11 +software and other kinds of works.
  12 +
  13 + The licenses for most software and other practical works are designed
  14 +to take away your freedom to share and change the works. By contrast,
  15 +the GNU General Public License is intended to guarantee your freedom to
  16 +share and change all versions of a program--to make sure it remains free
  17 +software for all its users. We, the Free Software Foundation, use the
  18 +GNU General Public License for most of our software; it applies also to
  19 +any other work released this way by its authors. You can apply it to
  20 +your programs, too.
  21 +
  22 + When we speak of free software, we are referring to freedom, not
  23 +price. Our General Public Licenses are designed to make sure that you
  24 +have the freedom to distribute copies of free software (and charge for
  25 +them if you wish), that you receive source code or can get it if you
  26 +want it, that you can change the software or use pieces of it in new
  27 +free programs, and that you know you can do these things.
  28 +
  29 + To protect your rights, we need to prevent others from denying you
  30 +these rights or asking you to surrender the rights. Therefore, you have
  31 +certain responsibilities if you distribute copies of the software, or if
  32 +you modify it: responsibilities to respect the freedom of others.
  33 +
  34 + For example, if you distribute copies of such a program, whether
  35 +gratis or for a fee, you must pass on to the recipients the same
  36 +freedoms that you received. You must make sure that they, too, receive
  37 +or can get the source code. And you must show them these terms so they
  38 +know their rights.
  39 +
  40 + Developers that use the GNU GPL protect your rights with two steps:
  41 +(1) assert copyright on the software, and (2) offer you this License
  42 +giving you legal permission to copy, distribute and/or modify it.
  43 +
  44 + For the developers' and authors' protection, the GPL clearly explains
  45 +that there is no warranty for this free software. For both users' and
  46 +authors' sake, the GPL requires that modified versions be marked as
  47 +changed, so that their problems will not be attributed erroneously to
  48 +authors of previous versions.
  49 +
  50 + Some devices are designed to deny users access to install or run
  51 +modified versions of the software inside them, although the manufacturer
  52 +can do so. This is fundamentally incompatible with the aim of
  53 +protecting users' freedom to change the software. The systematic
  54 +pattern of such abuse occurs in the area of products for individuals to
  55 +use, which is precisely where it is most unacceptable. Therefore, we
  56 +have designed this version of the GPL to prohibit the practice for those
  57 +products. If such problems arise substantially in other domains, we
  58 +stand ready to extend this provision to those domains in future versions
  59 +of the GPL, as needed to protect the freedom of users.
  60 +
  61 + Finally, every program is threatened constantly by software patents.
  62 +States should not allow patents to restrict development and use of
  63 +software on general-purpose computers, but in those that do, we wish to
  64 +avoid the special danger that patents applied to a free program could
  65 +make it effectively proprietary. To prevent this, the GPL assures that
  66 +patents cannot be used to render the program non-free.
  67 +
  68 + The precise terms and conditions for copying, distribution and
  69 +modification follow.
  70 +
  71 + TERMS AND CONDITIONS
  72 +
  73 + 0. Definitions.
  74 +
  75 + "This License" refers to version 3 of the GNU General Public License.
  76 +
  77 + "Copyright" also means copyright-like laws that apply to other kinds of
  78 +works, such as semiconductor masks.
  79 +
  80 + "The Program" refers to any copyrightable work licensed under this
  81 +License. Each licensee is addressed as "you". "Licensees" and
  82 +"recipients" may be individuals or organizations.
  83 +
  84 + To "modify" a work means to copy from or adapt all or part of the work
  85 +in a fashion requiring copyright permission, other than the making of an
  86 +exact copy. The resulting work is called a "modified version" of the
  87 +earlier work or a work "based on" the earlier work.
  88 +
  89 + A "covered work" means either the unmodified Program or a work based
  90 +on the Program.
  91 +
  92 + To "propagate" a work means to do anything with it that, without
  93 +permission, would make you directly or secondarily liable for
  94 +infringement under applicable copyright law, except executing it on a
  95 +computer or modifying a private copy. Propagation includes copying,
  96 +distribution (with or without modification), making available to the
  97 +public, and in some countries other activities as well.
  98 +
  99 + To "convey" a work means any kind of propagation that enables other
  100 +parties to make or receive copies. Mere interaction with a user through
  101 +a computer network, with no transfer of a copy, is not conveying.
  102 +
  103 + An interactive user interface displays "Appropriate Legal Notices"
  104 +to the extent that it includes a convenient and prominently visible
  105 +feature that (1) displays an appropriate copyright notice, and (2)
  106 +tells the user that there is no warranty for the work (except to the
  107 +extent that warranties are provided), that licensees may convey the
  108 +work under this License, and how to view a copy of this License. If
  109 +the interface presents a list of user commands or options, such as a
  110 +menu, a prominent item in the list meets this criterion.
  111 +
  112 + 1. Source Code.
  113 +
  114 + The "source code" for a work means the preferred form of the work
  115 +for making modifications to it. "Object code" means any non-source
  116 +form of a work.
  117 +
  118 + A "Standard Interface" means an interface that either is an official
  119 +standard defined by a recognized standards body, or, in the case of
  120 +interfaces specified for a particular programming language, one that
  121 +is widely used among developers working in that language.
  122 +
  123 + The "System Libraries" of an executable work include anything, other
  124 +than the work as a whole, that (a) is included in the normal form of
  125 +packaging a Major Component, but which is not part of that Major
  126 +Component, and (b) serves only to enable use of the work with that
  127 +Major Component, or to implement a Standard Interface for which an
  128 +implementation is available to the public in source code form. A
  129 +"Major Component", in this context, means a major essential component
  130 +(kernel, window system, and so on) of the specific operating system
  131 +(if any) on which the executable work runs, or a compiler used to
  132 +produce the work, or an object code interpreter used to run it.
  133 +
  134 + The "Corresponding Source" for a work in object code form means all
  135 +the source code needed to generate, install, and (for an executable
  136 +work) run the object code and to modify the work, including scripts to
  137 +control those activities. However, it does not include the work's
  138 +System Libraries, or general-purpose tools or generally available free
  139 +programs which are used unmodified in performing those activities but
  140 +which are not part of the work. For example, Corresponding Source
  141 +includes interface definition files associated with source files for
  142 +the work, and the source code for shared libraries and dynamically
  143 +linked subprograms that the work is specifically designed to require,
  144 +such as by intimate data communication or control flow between those
  145 +subprograms and other parts of the work.
  146 +
  147 + The Corresponding Source need not include anything that users
  148 +can regenerate automatically from other parts of the Corresponding
  149 +Source.
  150 +
  151 + The Corresponding Source for a work in source code form is that
  152 +same work.
  153 +
  154 + 2. Basic Permissions.
  155 +
  156 + All rights granted under this License are granted for the term of
  157 +copyright on the Program, and are irrevocable provided the stated
  158 +conditions are met. This License explicitly affirms your unlimited
  159 +permission to run the unmodified Program. The output from running a
  160 +covered work is covered by this License only if the output, given its
  161 +content, constitutes a covered work. This License acknowledges your
  162 +rights of fair use or other equivalent, as provided by copyright law.
  163 +
  164 + You may make, run and propagate covered works that you do not
  165 +convey, without conditions so long as your license otherwise remains
  166 +in force. You may convey covered works to others for the sole purpose
  167 +of having them make modifications exclusively for you, or provide you
  168 +with facilities for running those works, provided that you comply with
  169 +the terms of this License in conveying all material for which you do
  170 +not control copyright. Those thus making or running the covered works
  171 +for you must do so exclusively on your behalf, under your direction
  172 +and control, on terms that prohibit them from making any copies of
  173 +your copyrighted material outside their relationship with you.
  174 +
  175 + Conveying under any other circumstances is permitted solely under
  176 +the conditions stated below. Sublicensing is not allowed; section 10
  177 +makes it unnecessary.
  178 +
  179 + 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  180 +
  181 + No covered work shall be deemed part of an effective technological
  182 +measure under any applicable law fulfilling obligations under article
  183 +11 of the WIPO copyright treaty adopted on 20 December 1996, or
  184 +similar laws prohibiting or restricting circumvention of such
  185 +measures.
  186 +
  187 + When you convey a covered work, you waive any legal power to forbid
  188 +circumvention of technological measures to the extent such circumvention
  189 +is effected by exercising rights under this License with respect to
  190 +the covered work, and you disclaim any intention to limit operation or
  191 +modification of the work as a means of enforcing, against the work's
  192 +users, your or third parties' legal rights to forbid circumvention of
  193 +technological measures.
  194 +
  195 + 4. Conveying Verbatim Copies.
  196 +
  197 + You may convey verbatim copies of the Program's source code as you
  198 +receive it, in any medium, provided that you conspicuously and
  199 +appropriately publish on each copy an appropriate copyright notice;
  200 +keep intact all notices stating that this License and any
  201 +non-permissive terms added in accord with section 7 apply to the code;
  202 +keep intact all notices of the absence of any warranty; and give all
  203 +recipients a copy of this License along with the Program.
  204 +
  205 + You may charge any price or no price for each copy that you convey,
  206 +and you may offer support or warranty protection for a fee.
  207 +
  208 + 5. Conveying Modified Source Versions.
  209 +
  210 + You may convey a work based on the Program, or the modifications to
  211 +produce it from the Program, in the form of source code under the
  212 +terms of section 4, provided that you also meet all of these conditions:
  213 +
  214 + a) The work must carry prominent notices stating that you modified
  215 + it, and giving a relevant date.
  216 +
  217 + b) The work must carry prominent notices stating that it is
  218 + released under this License and any conditions added under section
  219 + 7. This requirement modifies the requirement in section 4 to
  220 + "keep intact all notices".
  221 +
  222 + c) You must license the entire work, as a whole, under this
  223 + License to anyone who comes into possession of a copy. This
  224 + License will therefore apply, along with any applicable section 7
  225 + additional terms, to the whole of the work, and all its parts,
  226 + regardless of how they are packaged. This License gives no
  227 + permission to license the work in any other way, but it does not
  228 + invalidate such permission if you have separately received it.
  229 +
  230 + d) If the work has interactive user interfaces, each must display
  231 + Appropriate Legal Notices; however, if the Program has interactive
  232 + interfaces that do not display Appropriate Legal Notices, your
  233 + work need not make them do so.
  234 +
  235 + A compilation of a covered work with other separate and independent
  236 +works, which are not by their nature extensions of the covered work,
  237 +and which are not combined with it such as to form a larger program,
  238 +in or on a volume of a storage or distribution medium, is called an
  239 +"aggregate" if the compilation and its resulting copyright are not
  240 +used to limit the access or legal rights of the compilation's users
  241 +beyond what the individual works permit. Inclusion of a covered work
  242 +in an aggregate does not cause this License to apply to the other
  243 +parts of the aggregate.
  244 +
  245 + 6. Conveying Non-Source Forms.
  246 +
  247 + You may convey a covered work in object code form under the terms
  248 +of sections 4 and 5, provided that you also convey the
  249 +machine-readable Corresponding Source under the terms of this License,
  250 +in one of these ways:
  251 +
  252 + a) Convey the object code in, or embodied in, a physical product
  253 + (including a physical distribution medium), accompanied by the
  254 + Corresponding Source fixed on a durable physical medium
  255 + customarily used for software interchange.
  256 +
  257 + b) Convey the object code in, or embodied in, a physical product
  258 + (including a physical distribution medium), accompanied by a
  259 + written offer, valid for at least three years and valid for as
  260 + long as you offer spare parts or customer support for that product
  261 + model, to give anyone who possesses the object code either (1) a
  262 + copy of the Corresponding Source for all the software in the
  263 + product that is covered by this License, on a durable physical
  264 + medium customarily used for software interchange, for a price no
  265 + more than your reasonable cost of physically performing this
  266 + conveying of source, or (2) access to copy the
  267 + Corresponding Source from a network server at no charge.
  268 +
  269 + c) Convey individual copies of the object code with a copy of the
  270 + written offer to provide the Corresponding Source. This
  271 + alternative is allowed only occasionally and noncommercially, and
  272 + only if you received the object code with such an offer, in accord
  273 + with subsection 6b.
  274 +
  275 + d) Convey the object code by offering access from a designated
  276 + place (gratis or for a charge), and offer equivalent access to the
  277 + Corresponding Source in the same way through the same place at no
  278 + further charge. You need not require recipients to copy the
  279 + Corresponding Source along with the object code. If the place to
  280 + copy the object code is a network server, the Corresponding Source
  281 + may be on a different server (operated by you or a third party)
  282 + that supports equivalent copying facilities, provided you maintain
  283 + clear directions next to the object code saying where to find the
  284 + Corresponding Source. Regardless of what server hosts the
  285 + Corresponding Source, you remain obligated to ensure that it is
  286 + available for as long as needed to satisfy these requirements.
  287 +
  288 + e) Convey the object code using peer-to-peer transmission, provided
  289 + you inform other peers where the object code and Corresponding
  290 + Source of the work are being offered to the general public at no
  291 + charge under subsection 6d.
  292 +
  293 + A separable portion of the object code, whose source code is excluded
  294 +from the Corresponding Source as a System Library, need not be
  295 +included in conveying the object code work.
  296 +
  297 + A "User Product" is either (1) a "consumer product", which means any
  298 +tangible personal property which is normally used for personal, family,
  299 +or household purposes, or (2) anything designed or sold for incorporation
  300 +into a dwelling. In determining whether a product is a consumer product,
  301 +doubtful cases shall be resolved in favor of coverage. For a particular
  302 +product received by a particular user, "normally used" refers to a
  303 +typical or common use of that class of product, regardless of the status
  304 +of the particular user or of the way in which the particular user
  305 +actually uses, or expects or is expected to use, the product. A product
  306 +is a consumer product regardless of whether the product has substantial
  307 +commercial, industrial or non-consumer uses, unless such uses represent
  308 +the only significant mode of use of the product.
  309 +
  310 + "Installation Information" for a User Product means any methods,
  311 +procedures, authorization keys, or other information required to install
  312 +and execute modified versions of a covered work in that User Product from
  313 +a modified version of its Corresponding Source. The information must
  314 +suffice to ensure that the continued functioning of the modified object
  315 +code is in no case prevented or interfered with solely because
  316 +modification has been made.
  317 +
  318 + If you convey an object code work under this section in, or with, or
  319 +specifically for use in, a User Product, and the conveying occurs as
  320 +part of a transaction in which the right of possession and use of the
  321 +User Product is transferred to the recipient in perpetuity or for a
  322 +fixed term (regardless of how the transaction is characterized), the
  323 +Corresponding Source conveyed under this section must be accompanied
  324 +by the Installation Information. But this requirement does not apply
  325 +if neither you nor any third party retains the ability to install
  326 +modified object code on the User Product (for example, the work has
  327 +been installed in ROM).
  328 +
  329 + The requirement to provide Installation Information does not include a
  330 +requirement to continue to provide support service, warranty, or updates
  331 +for a work that has been modified or installed by the recipient, or for
  332 +the User Product in which it has been modified or installed. Access to a
  333 +network may be denied when the modification itself materially and
  334 +adversely affects the operation of the network or violates the rules and
  335 +protocols for communication across the network.
  336 +
  337 + Corresponding Source conveyed, and Installation Information provided,
  338 +in accord with this section must be in a format that is publicly
  339 +documented (and with an implementation available to the public in
  340 +source code form), and must require no special password or key for
  341 +unpacking, reading or copying.
  342 +
  343 + 7. Additional Terms.
  344 +
  345 + "Additional permissions" are terms that supplement the terms of this
  346 +License by making exceptions from one or more of its conditions.
  347 +Additional permissions that are applicable to the entire Program shall
  348 +be treated as though they were included in this License, to the extent
  349 +that they are valid under applicable law. If additional permissions
  350 +apply only to part of the Program, that part may be used separately
  351 +under those permissions, but the entire Program remains governed by
  352 +this License without regard to the additional permissions.
  353 +
  354 + When you convey a copy of a covered work, you may at your option
  355 +remove any additional permissions from that copy, or from any part of
  356 +it. (Additional permissions may be written to require their own
  357 +removal in certain cases when you modify the work.) You may place
  358 +additional permissions on material, added by you to a covered work,
  359 +for which you have or can give appropriate copyright permission.
  360 +
  361 + Notwithstanding any other provision of this License, for material you
  362 +add to a covered work, you may (if authorized by the copyright holders of
  363 +that material) supplement the terms of this License with terms:
  364 +
  365 + a) Disclaiming warranty or limiting liability differently from the
  366 + terms of sections 15 and 16 of this License; or
  367 +
  368 + b) Requiring preservation of specified reasonable legal notices or
  369 + author attributions in that material or in the Appropriate Legal
  370 + Notices displayed by works containing it; or
  371 +
  372 + c) Prohibiting misrepresentation of the origin of that material, or
  373 + requiring that modified versions of such material be marked in
  374 + reasonable ways as different from the original version; or
  375 +
  376 + d) Limiting the use for publicity purposes of names of licensors or
  377 + authors of the material; or
  378 +
  379 + e) Declining to grant rights under trademark law for use of some
  380 + trade names, trademarks, or service marks; or
  381 +
  382 + f) Requiring indemnification of licensors and authors of that
  383 + material by anyone who conveys the material (or modified versions of
  384 + it) with contractual assumptions of liability to the recipient, for
  385 + any liability that these contractual assumptions directly impose on
  386 + those licensors and authors.
  387 +
  388 + All other non-permissive additional terms are considered "further
  389 +restrictions" within the meaning of section 10. If the Program as you
  390 +received it, or any part of it, contains a notice stating that it is
  391 +governed by this License along with a term that is a further
  392 +restriction, you may remove that term. If a license document contains
  393 +a further restriction but permits relicensing or conveying under this
  394 +License, you may add to a covered work material governed by the terms
  395 +of that license document, provided that the further restriction does
  396 +not survive such relicensing or conveying.
  397 +
  398 + If you add terms to a covered work in accord with this section, you
  399 +must place, in the relevant source files, a statement of the
  400 +additional terms that apply to those files, or a notice indicating
  401 +where to find the applicable terms.
  402 +
  403 + Additional terms, permissive or non-permissive, may be stated in the
  404 +form of a separately written license, or stated as exceptions;
  405 +the above requirements apply either way.
  406 +
  407 + 8. Termination.
  408 +
  409 + You may not propagate or modify a covered work except as expressly
  410 +provided under this License. Any attempt otherwise to propagate or
  411 +modify it is void, and will automatically terminate your rights under
  412 +this License (including any patent licenses granted under the third
  413 +paragraph of section 11).
  414 +
  415 + However, if you cease all violation of this License, then your
  416 +license from a particular copyright holder is reinstated (a)
  417 +provisionally, unless and until the copyright holder explicitly and
  418 +finally terminates your license, and (b) permanently, if the copyright
  419 +holder fails to notify you of the violation by some reasonable means
  420 +prior to 60 days after the cessation.
  421 +
  422 + Moreover, your license from a particular copyright holder is
  423 +reinstated permanently if the copyright holder notifies you of the
  424 +violation by some reasonable means, this is the first time you have
  425 +received notice of violation of this License (for any work) from that
  426 +copyright holder, and you cure the violation prior to 30 days after
  427 +your receipt of the notice.
  428 +
  429 + Termination of your rights under this section does not terminate the
  430 +licenses of parties who have received copies or rights from you under
  431 +this License. If your rights have been terminated and not permanently
  432 +reinstated, you do not qualify to receive new licenses for the same
  433 +material under section 10.
  434 +
  435 + 9. Acceptance Not Required for Having Copies.
  436 +
  437 + You are not required to accept this License in order to receive or
  438 +run a copy of the Program. Ancillary propagation of a covered work
  439 +occurring solely as a consequence of using peer-to-peer transmission
  440 +to receive a copy likewise does not require acceptance. However,
  441 +nothing other than this License grants you permission to propagate or
  442 +modify any covered work. These actions infringe copyright if you do
  443 +not accept this License. Therefore, by modifying or propagating a
  444 +covered work, you indicate your acceptance of this License to do so.
  445 +
  446 + 10. Automatic Licensing of Downstream Recipients.
  447 +
  448 + Each time you convey a covered work, the recipient automatically
  449 +receives a license from the original licensors, to run, modify and
  450 +propagate that work, subject to this License. You are not responsible
  451 +for enforcing compliance by third parties with this License.
  452 +
  453 + An "entity transaction" is a transaction transferring control of an
  454 +organization, or substantially all assets of one, or subdividing an
  455 +organization, or merging organizations. If propagation of a covered
  456 +work results from an entity transaction, each party to that
  457 +transaction who receives a copy of the work also receives whatever
  458 +licenses to the work the party's predecessor in interest had or could
  459 +give under the previous paragraph, plus a right to possession of the
  460 +Corresponding Source of the work from the predecessor in interest, if
  461 +the predecessor has it or can get it with reasonable efforts.
  462 +
  463 + You may not impose any further restrictions on the exercise of the
  464 +rights granted or affirmed under this License. For example, you may
  465 +not impose a license fee, royalty, or other charge for exercise of
  466 +rights granted under this License, and you may not initiate litigation
  467 +(including a cross-claim or counterclaim in a lawsuit) alleging that
  468 +any patent claim is infringed by making, using, selling, offering for
  469 +sale, or importing the Program or any portion of it.
  470 +
  471 + 11. Patents.
  472 +
  473 + A "contributor" is a copyright holder who authorizes use under this
  474 +License of the Program or a work on which the Program is based. The
  475 +work thus licensed is called the contributor's "contributor version".
  476 +
  477 + A contributor's "essential patent claims" are all patent claims
  478 +owned or controlled by the contributor, whether already acquired or
  479 +hereafter acquired, that would be infringed by some manner, permitted
  480 +by this License, of making, using, or selling its contributor version,
  481 +but do not include claims that would be infringed only as a
  482 +consequence of further modification of the contributor version. For
  483 +purposes of this definition, "control" includes the right to grant
  484 +patent sublicenses in a manner consistent with the requirements of
  485 +this License.
  486 +
  487 + Each contributor grants you a non-exclusive, worldwide, royalty-free
  488 +patent license under the contributor's essential patent claims, to
  489 +make, use, sell, offer for sale, import and otherwise run, modify and
  490 +propagate the contents of its contributor version.
  491 +
  492 + In the following three paragraphs, a "patent license" is any express
  493 +agreement or commitment, however denominated, not to enforce a patent
  494 +(such as an express permission to practice a patent or covenant not to
  495 +sue for patent infringement). To "grant" such a patent license to a
  496 +party means to make such an agreement or commitment not to enforce a
  497 +patent against the party.
  498 +
  499 + If you convey a covered work, knowingly relying on a patent license,
  500 +and the Corresponding Source of the work is not available for anyone
  501 +to copy, free of charge and under the terms of this License, through a
  502 +publicly available network server or other readily accessible means,
  503 +then you must either (1) cause the Corresponding Source to be so
  504 +available, or (2) arrange to deprive yourself of the benefit of the
  505 +patent license for this particular work, or (3) arrange, in a manner
  506 +consistent with the requirements of this License, to extend the patent
  507 +license to downstream recipients. "Knowingly relying" means you have
  508 +actual knowledge that, but for the patent license, your conveying the
  509 +covered work in a country, or your recipient's use of the covered work
  510 +in a country, would infringe one or more identifiable patents in that
  511 +country that you have reason to believe are valid.
  512 +
  513 + If, pursuant to or in connection with a single transaction or
  514 +arrangement, you convey, or propagate by procuring conveyance of, a
  515 +covered work, and grant a patent license to some of the parties
  516 +receiving the covered work authorizing them to use, propagate, modify
  517 +or convey a specific copy of the covered work, then the patent license
  518 +you grant is automatically extended to all recipients of the covered
  519 +work and works based on it.
  520 +
  521 + A patent license is "discriminatory" if it does not include within
  522 +the scope of its coverage, prohibits the exercise of, or is
  523 +conditioned on the non-exercise of one or more of the rights that are
  524 +specifically granted under this License. You may not convey a covered
  525 +work if you are a party to an arrangement with a third party that is
  526 +in the business of distributing software, under which you make payment
  527 +to the third party based on the extent of your activity of conveying
  528 +the work, and under which the third party grants, to any of the
  529 +parties who would receive the covered work from you, a discriminatory
  530 +patent license (a) in connection with copies of the covered work
  531 +conveyed by you (or copies made from those copies), or (b) primarily
  532 +for and in connection with specific products or compilations that
  533 +contain the covered work, unless you entered into that arrangement,
  534 +or that patent license was granted, prior to 28 March 2007.
  535 +
  536 + Nothing in this License shall be construed as excluding or limiting
  537 +any implied license or other defenses to infringement that may
  538 +otherwise be available to you under applicable patent law.
  539 +
  540 + 12. No Surrender of Others' Freedom.
  541 +
  542 + If conditions are imposed on you (whether by court order, agreement or
  543 +otherwise) that contradict the conditions of this License, they do not
  544 +excuse you from the conditions of this License. If you cannot convey a
  545 +covered work so as to satisfy simultaneously your obligations under this
  546 +License and any other pertinent obligations, then as a consequence you may
  547 +not convey it at all. For example, if you agree to terms that obligate you
  548 +to collect a royalty for further conveying from those to whom you convey
  549 +the Program, the only way you could satisfy both those terms and this
  550 +License would be to refrain entirely from conveying the Program.
  551 +
  552 + 13. Use with the GNU Affero General Public License.
  553 +
  554 + Notwithstanding any other provision of this License, you have
  555 +permission to link or combine any covered work with a work licensed
  556 +under version 3 of the GNU Affero General Public License into a single
  557 +combined work, and to convey the resulting work. The terms of this
  558 +License will continue to apply to the part which is the covered work,
  559 +but the special requirements of the GNU Affero General Public License,
  560 +section 13, concerning interaction through a network will apply to the
  561 +combination as such.
  562 +
  563 + 14. Revised Versions of this License.
  564 +
  565 + The Free Software Foundation may publish revised and/or new versions of
  566 +the GNU General Public License from time to time. Such new versions will
  567 +be similar in spirit to the present version, but may differ in detail to
  568 +address new problems or concerns.
  569 +
  570 + Each version is given a distinguishing version number. If the
  571 +Program specifies that a certain numbered version of the GNU General
  572 +Public License "or any later version" applies to it, you have the
  573 +option of following the terms and conditions either of that numbered
  574 +version or of any later version published by the Free Software
  575 +Foundation. If the Program does not specify a version number of the
  576 +GNU General Public License, you may choose any version ever published
  577 +by the Free Software Foundation.
  578 +
  579 + If the Program specifies that a proxy can decide which future
  580 +versions of the GNU General Public License can be used, that proxy's
  581 +public statement of acceptance of a version permanently authorizes you
  582 +to choose that version for the Program.
  583 +
  584 + Later license versions may give you additional or different
  585 +permissions. However, no additional obligations are imposed on any
  586 +author or copyright holder as a result of your choosing to follow a
  587 +later version.
  588 +
  589 + 15. Disclaimer of Warranty.
  590 +
  591 + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
  592 +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
  593 +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
  594 +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
  595 +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  596 +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
  597 +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
  598 +ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  599 +
  600 + 16. Limitation of Liability.
  601 +
  602 + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  603 +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
  604 +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
  605 +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
  606 +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
  607 +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
  608 +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
  609 +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
  610 +SUCH DAMAGES.
  611 +
  612 + 17. Interpretation of Sections 15 and 16.
  613 +
  614 + If the disclaimer of warranty and limitation of liability provided
  615 +above cannot be given local legal effect according to their terms,
  616 +reviewing courts shall apply local law that most closely approximates
  617 +an absolute waiver of all civil liability in connection with the
  618 +Program, unless a warranty or assumption of liability accompanies a
  619 +copy of the Program in return for a fee.
  620 +
  621 + END OF TERMS AND CONDITIONS
  622 +
  623 + How to Apply These Terms to Your New Programs
  624 +
  625 + If you develop a new program, and you want it to be of the greatest
  626 +possible use to the public, the best way to achieve this is to make it
  627 +free software which everyone can redistribute and change under these terms.
  628 +
  629 + To do so, attach the following notices to the program. It is safest
  630 +to attach them to the start of each source file to most effectively
  631 +state the exclusion of warranty; and each file should have at least
  632 +the "copyright" line and a pointer to where the full notice is found.
  633 +
  634 + <one line to give the program's name and a brief idea of what it does.>
  635 + Copyright (C) <year> <name of author>
  636 +
  637 + This program is free software: you can redistribute it and/or modify
  638 + it under the terms of the GNU General Public License as published by
  639 + the Free Software Foundation, either version 3 of the License, or
  640 + (at your option) any later version.
  641 +
  642 + This program is distributed in the hope that it will be useful,
  643 + but WITHOUT ANY WARRANTY; without even the implied warranty of
  644 + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
  645 + GNU General Public License for more details.
  646 +
  647 + You should have received a copy of the GNU General Public License
  648 + along with this program. If not, see <http://www.gnu.org/licenses/>.
  649 +
  650 +Also add information on how to contact you by electronic and paper mail.
  651 +
  652 + If the program does terminal interaction, make it output a short
  653 +notice like this when it starts in an interactive mode:
  654 +
  655 + <program> Copyright (C) <year> <name of author>
  656 + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
  657 + This is free software, and you are welcome to redistribute it
  658 + under certain conditions; type `show c' for details.
  659 +
  660 +The hypothetical commands `show w' and `show c' should show the appropriate
  661 +parts of the General Public License. Of course, your program's commands
  662 +might be different; for a GUI interface, you would use an "about box".
  663 +
  664 + You should also get your employer (if you work as a programmer) or school,
  665 +if any, to sign a "copyright disclaimer" for the program, if necessary.
  666 +For more information on this, and how to apply and follow the GNU GPL, see
  667 +<http://www.gnu.org/licenses/>.
  668 +
  669 + The GNU General Public License does not permit incorporating your program
  670 +into proprietary programs. If your program is a subroutine library, you
  671 +may consider it more useful to permit linking proprietary applications with
  672 +the library. If this is what you want to do, use the GNU Lesser General
  673 +Public License instead of this License. But first, please read
  674 +<http://www.gnu.org/philosophy/why-not-lgpl.html>.

  6 +1 - About
  7 +This is an Arduino makefile, an alternative to the current IDE, which
  8 +I made in hope to help the Arduino community.
  9 +It will build your source code and any library you want to use with
  10 +it. I've also created a quite simple Serial.printf(const char *, ...),
  11 +it currently only works with %d and %s, but better than nothing.
  12 +It is in the file ./lib/default/Print.cpp, if you want to see it.
  13 +
  14 +You may use this for any porpuse, and edit as you want. This code is
  15 +released under the GPL license. It is not needed at all, but it would
  16 +be apreciated if you comment you used my software, or just send me an
  17 +e-mail with thanks. =D
  18 +
  19 +Enjoy, folks.

  38 +3 - The Output
  39 +The output files will be all the libraries *.a files, the binary
  40 +"project.elf" file, which is converted to "project.hex". This final
  41 +file is then uploaded by running "make upload".
  42 +
  43 +4 - Makefile
  44 +The Makefile is automatically generated every time a modification to
  45 +some directory, to the Makefile and to the generator itself (so it is
  46 +useless to edit it, as it will be recreated).
  47 +It is created by scripts/make.rb, and uses scripts/size.rb to check
  48 +the size of the final program.
  49 +The generator will create all the libraries and the program itself,
  50 +scanning the folders recursivelly.
  51 +Some rules:
  52 +"make":
  53 + will generate the final file, "project.hex". It will
  54 + recreate the Makefile itself if necessary.
  55 +"make upload":
  56 + generates the file (if not generated yet) and
  57 + then uploads it to the Arduino board. It is not necessary to
  58 + call "make" before it, because it checks if the final file is
  59 + up to date before doing the upload itself. It will also check the
  60 + binary size.
  61 + The default port is /dev/tty0, to change the number you can, e.g.,
  62 + call "make USB=1" to use /dev/tty1 instead.
  63 +"make clean": deletes all the files created by the project (i.e.,
  64 + all the *.o files, *.a libraries, the "project.elf" and the "project.hex".
  65 +
  66 +5 - Libraries
  67 + Libraries may be reused in another project. Each directory inside
  68 +the "lib" directory is considered a different library (e.g., the
  69 +"default" directory will generate the library default.a, with all the
  70 +source codes it may find inside lib/default (scanning recursivelly).
  71 + To create a new lib, e.g., "foo", create a directory foo in the
  72 +"lib" directory, and populate it with *.c or *.cpp files. The
  73 +Makefile will be automatically recreated and the library rule will
  74 +have been made, and a foo.a file will appear (and will be added to
  75 +the final executable).
