    "\n"++
    "                            Preamble\n"++
    "\n"++
    "  The GNU General Public License is a free, copyleft license for\n"++
    "software and other kinds of works.\n"++
    "\n"++
    "  The licenses for most software and other practical works are designed\n"++
    "to take away your freedom to share and change the works.  By contrast,\n"++
    "the GNU General Public License is intended to guarantee your freedom to\n"++
    "share and change all versions of a program--to make sure it remains free\n"++
    "software for all its users.  We, the Free Software Foundation, use the\n"++
    "GNU General Public License for most of our software; it applies also to\n"++
    "any other work released this way by its authors.  You can apply it to\n"++
    "your programs, too.\n"++
    "\n"++
    "  When we speak of free software, we are referring to freedom, not\n"++
    "price.  Our General Public Licenses are designed to make sure that you\n"++
    "have the freedom to distribute copies of free software (and charge for\n"++
    "them if you wish), that you receive source code or can get it if you\n"++
    "want it, that you can change the software or use pieces of it in new\n"++
    "free programs, and that you know you can do these things.\n"++
    "\n"++
    "  To protect your rights, we need to prevent others from denying you\n"++
    "these rights or asking you to surrender the rights.  Therefore, you have\n"++
    "certain responsibilities if you distribute copies of the software, or if\n"++
    "you modify it: responsibilities to respect the freedom of others.\n"++
    "\n"++
    "  For example, if you distribute copies of such a program, whether\n"++
    "gratis or for a fee, you must pass on to the recipients the same\n"++
    "freedoms that you received.  You must make sure that they, too, receive\n"++
    "or can get the source code.  And you must show them these terms so they\n"++
    "know their rights.\n"++
    "\n"++
    "  Developers that use the GNU GPL protect your rights with two steps:\n"++
    "(1) assert copyright on the software, and (2) offer you this License\n"++
    "giving you legal permission to copy, distribute and/or modify it.\n"++
    "\n"++
    "  For the developers' and authors' protection, the GPL clearly explains\n"++
    "that there is no warranty for this free software.  For both users' and\n"++
    "authors' sake, the GPL requires that modified versions be marked as\n"++
    "changed, so that their problems will not be attributed erroneously to\n"++
    "authors of previous versions.\n"++
    "\n"++
    "  Some devices are designed to deny users access to install or run\n"++
    "modified versions of the software inside them, although the manufacturer\n"++
    "can do so.  This is fundamentally incompatible with the aim of\n"++
    "protecting users' freedom to change the software.  The systematic\n"++
    "pattern of such abuse occurs in the area of products for individuals to\n"++
    "use, which is precisely where it is most unacceptable.  Therefore, we\n"++
    "have designed this version of the GPL to prohibit the practice for those\n"++
    "products.  If such problems arise substantially in other domains, we\n"++
    "stand ready to extend this provision to those domains in future versions\n"++
    "of the GPL, as needed to protect the freedom of users.\n"++
    "\n"++
    "  Finally, every program is threatened constantly by software patents.\n"++
    "States should not allow patents to restrict development and use of\n"++
    "software on general-purpose computers, but in those that do, we wish to\n"++
    "avoid the special danger that patents applied to a free program could\n"++
    "make it effectively proprietary.  To prevent this, the GPL assures that\n"++
    "patents cannot be used to render the program non-free.\n"++
    "\n"++
    "  The precise terms and conditions for copying, distribution and\n"++
    "modification follow.\n"++
    "\n"++
    "                       TERMS AND CONDITIONS\n"++
    "\n"++
    "  0. Definitions.\n"++
    "\n"++
    "  \"This License\" refers to version 3 of the GNU General Public License.\n"++
    "\n"++
    "  \"Copyright\" also means copyright-like laws that apply to other kinds of\n"++
    "works, such as semiconductor masks.\n"++
    "\n"++
    "  \"The Program\" refers to any copyrightable work licensed under this\n"++
    "License.  Each licensee is addressed as \"you\".  \"Licensees\" and\n"++
    "\"recipients\" may be individuals or organizations.\n"++
    "\n"++
    "  To \"modify\" a work means to copy from or adapt all or part of the work\n"++
    "in a fashion requiring copyright permission, other than the making of an\n"++
    "exact copy.  The resulting work is called a \"modified version\" of the\n"++
    "earlier work or a work \"based on\" the earlier work.\n"++
    "\n"++
    "  A \"covered work\" means either the unmodified Program or a work based\n"++
    "on the Program.\n"++
    "\n"++
    "  To \"propagate\" a work means to do anything with it that, without\n"++
    "permission, would make you directly or secondarily liable for\n"++
    "infringement under applicable copyright law, except executing it on a\n"++
    "computer or modifying a private copy.  Propagation includes copying,\n"++
    "distribution (with or without modification), making available to the\n"++
    "public, and in some countries other activities as well.\n"++
    "\n"++
    "  To \"convey\" a work means any kind of propagation that enables other\n"++
    "parties to make or receive copies.  Mere interaction with a user through\n"++
    "a computer network, with no transfer of a copy, is not conveying.\n"++
    "\n"++
    "  An interactive user interface displays \"Appropriate Legal Notices\"\n"++
    "to the extent that it includes a convenient and prominently visible\n"++
    "feature that (1) displays an appropriate copyright notice, and (2)\n"++
    "tells the user that there is no warranty for the work (except to the\n"++
    "extent that warranties are provided), that licensees may convey the\n"++
    "work under this License, and how to view a copy of this License.  If\n"++
    "the interface presents a list of user commands or options, such as a\n"++
    "menu, a prominent item in the list meets this criterion.\n"++
    "\n"++
    "  1. Source Code.\n"++
    "\n"++
    "  The \"source code\" for a work means the preferred form of the work\n"++
    "for making modifications to it.  \"Object code\" means any non-source\n"++
    "form of a work.\n"++
    "\n"++
    "  A \"Standard Interface\" means an interface that either is an official\n"++
    "standard defined by a recognized standards body, or, in the case of\n"++
    "interfaces specified for a particular programming language, one that\n"++
    "is widely used among developers working in that language.\n"++
    "\n"++
    "  The \"System Libraries\" of an executable work include anything, other\n"++
    "than the work as a whole, that (a) is included in the normal form of\n"++
    "packaging a Major Component, but which is not part of that Major\n"++
    "Component, and (b) serves only to enable use of the work with that\n"++
    "Major Component, or to implement a Standard Interface for which an\n"++
    "implementation is available to the public in source code form.  A\n"++
    "\"Major Component\", in this context, means a major essential component\n"++
    "(kernel, window system, and so on) of the specific operating system\n"++
    "(if any) on which the executable work runs, or a compiler used to\n"++
    "produce the work, or an object code interpreter used to run it.\n"++
    "\n"++
    "  The \"Corresponding Source\" for a work in object code form means all\n"++
    "the source code needed to generate, install, and (for an executable\n"++
    "work) run the object code and to modify the work, including scripts to\n"++
    "control those activities.  However, it does not include the work's\n"++
    "System Libraries, or general-purpose tools or generally available free\n"++
    "programs which are used unmodified in performing those activities but\n"++
    "which are not part of the work.  For example, Corresponding Source\n"++
    "includes interface definition files associated with source files for\n"++
    "the work, and the source code for shared libraries and dynamically\n"++
    "linked subprograms that the work is specifically designed to require,\n"++
    "such as by intimate data communication or control flow between those\n"++
    "subprograms and other parts of the work.\n"++
    "\n"++
    "  The Corresponding Source need not include anything that users\n"++
    "can regenerate automatically from other parts of the Corresponding\n"++
    "Source.\n"++
    "\n"++
    "  The Corresponding Source for a work in source code form is that\n"++
    "same work.\n"++
    "\n"++
    "  2. Basic Permissions.\n"++
    "\n"++
    "  All rights granted under this License are granted for the term of\n"++
    "copyright on the Program, and are irrevocable provided the stated\n"++
    "conditions are met.  This License explicitly affirms your unlimited\n"++
    "permission to run the unmodified Program.  The output from running a\n"++
    "covered work is covered by this License only if the output, given its\n"++
    "content, constitutes a covered work.  This License acknowledges your\n"++
    "rights of fair use or other equivalent, as provided by copyright law.\n"++
    "\n"++
    "  You may make, run and propagate covered works that you do not\n"++
    "convey, without conditions so long as your license otherwise remains\n"++
    "in force.  You may convey covered works to others for the sole purpose\n"++
    "of having them make modifications exclusively for you, or provide you\n"++
    "with facilities for running those works, provided that you comply with\n"++
    "the terms of this License in conveying all material for which you do\n"++
    "not control copyright.  Those thus making or running the covered works\n"++
    "for you must do so exclusively on your behalf, under your direction\n"++
    "and control, on terms that prohibit them from making any copies of\n"++
    "your copyrighted material outside their relationship with you.\n"++
    "\n"++
    "  Conveying under any other circumstances is permitted solely under\n"++
    "the conditions stated below.  Sublicensing is not allowed; section 10\n"++
    "makes it unnecessary.\n"++
    "\n"++
    "  3. Protecting Users' Legal Rights From Anti-Circumvention Law.\n"++
    "\n"++
    "  No covered work shall be deemed part of an effective technological\n"++
    "measure under any applicable law fulfilling obligations under article\n"++
    "11 of the WIPO copyright treaty adopted on 20 December 1996, or\n"++
    "similar laws prohibiting or restricting circumvention of such\n"++
    "measures.\n"++
    "\n"++
    "  When you convey a covered work, you waive any legal power to forbid\n"++
    "circumvention of technological measures to the extent such circumvention\n"++
    "is effected by exercising rights under this License with respect to\n"++
    "the covered work, and you disclaim any intention to limit operation or\n"++
    "modification of the work as a means of enforcing, against the work's\n"++
    "users, your or third parties' legal rights to forbid circumvention of\n"++
    "technological measures.\n"++
    "\n"++
    "  4. Conveying Verbatim Copies.\n"++
    "\n"++
    "  You may convey verbatim copies of the Program's source code as you\n"++
    "receive it, in any medium, provided that you conspicuously and\n"++
    "appropriately publish on each copy an appropriate copyright notice;\n"++
    "keep intact all notices stating that this License and any\n"++
    "non-permissive terms added in accord with section 7 apply to the code;\n"++
    "keep intact all notices of the absence of any warranty; and give all\n"++
    "recipients a copy of this License along with the Program.\n"++
    "\n"++
    "  You may charge any price or no price for each copy that you convey,\n"++
    "and you may offer support or warranty protection for a fee.\n"++
    "\n"++
    "  5. Conveying Modified Source Versions.\n"++
    "\n"++
    "  You may convey a work based on the Program, or the modifications to\n"++
    "produce it from the Program, in the form of source code under the\n"++
    "terms of section 4, provided that you also meet all of these conditions:\n"++
    "\n"++
    "    a) The work must carry prominent notices stating that you modified\n"++
    "    it, and giving a relevant date.\n"++
    "\n"++
    "    b) The work must carry prominent notices stating that it is\n"++
    "    released under this License and any conditions added under section\n"++
    "    7.  This requirement modifies the requirement in section 4 to\n"++
    "    \"keep intact all notices\".\n"++
    "\n"++
    "    c) You must license the entire work, as a whole, under this\n"++
    "    License to anyone who comes into possession of a copy.  This\n"++
    "    License will therefore apply, along with any applicable section 7\n"++
    "    additional terms, to the whole of the work, and all its parts,\n"++
    "    regardless of how they are packaged.  This License gives no\n"++
    "    permission to license the work in any other way, but it does not\n"++
    "    invalidate such permission if you have separately received it.\n"++
    "\n"++
    "    d) If the work has interactive user interfaces, each must display\n"++
    "    Appropriate Legal Notices; however, if the Program has interactive\n"++
    "    interfaces that do not display Appropriate Legal Notices, your\n"++
    "    work need not make them do so.\n"++
    "\n"++
    "  A compilation of a covered work with other separate and independent\n"++
    "works, which are not by their nature extensions of the covered work,\n"++
    "and which are not combined with it such as to form a larger program,\n"++
    "in or on a volume of a storage or distribution medium, is called an\n"++
    "\"aggregate\" if the compilation and its resulting copyright are not\n"++
    "used to limit the access or legal rights of the compilation's users\n"++
    "beyond what the individual works permit.  Inclusion of a covered work\n"++
    "in an aggregate does not cause this License to apply to the other\n"++
    "parts of the aggregate.\n"++
    "\n"++
    "  6. Conveying Non-Source Forms.\n"++
    "\n"++
    "  You may convey a covered work in object code form under the terms\n"++
    "of sections 4 and 5, provided that you also convey the\n"++
    "machine-readable Corresponding Source under the terms of this License,\n"++
    "in one of these ways:\n"++
    "\n"++
    "    a) Convey the object code in, or embodied in, a physical product\n"++
    "    (including a physical distribution medium), accompanied by the\n"++
    "    Corresponding Source fixed on a durable physical medium\n"++
    "    customarily used for software interchange.\n"++
    "\n"++
    "    b) Convey the object code in, or embodied in, a physical product\n"++
    "    (including a physical distribution medium), accompanied by a\n"++
    "    written offer, valid for at least three years and valid for as\n"++
    "    long as you offer spare parts or customer support for that product\n"++
    "    model, to give anyone who possesses the object code either (1) a\n"++
    "    copy of the Corresponding Source for all the software in the\n"++
    "    product that is covered by this License, on a durable physical\n"++
    "    medium customarily used for software interchange, for a price no\n"++
    "    more than your reasonable cost of physically performing this\n"++
    "    conveying of source, or (2) access to copy the\n"++
    "    Corresponding Source from a network server at no charge.\n"++
    "\n"++
    "    c) Convey individual copies of the object code with a copy of the\n"++
    "    written offer to provide the Corresponding Source.  This\n"++
    "    alternative is allowed only occasionally and noncommercially, and\n"++
    "    only if you received the object code with such an offer, in accord\n"++
    "    with subsection 6b.\n"++
    "\n"++
    "    d) Convey the object code by offering access from a designated\n"++
    "    place (gratis or for a charge), and offer equivalent access to the\n"++
    "    Corresponding Source in the same way through the same place at no\n"++
    "    further charge.  You need not require recipients to copy the\n"++
    "    Corresponding Source along with the object code.  If the place to\n"++
    "    copy the object code is a network server, the Corresponding Source\n"++
    "    may be on a different server (operated by you or a third party)\n"++
    "    that supports equivalent copying facilities, provided you maintain\n"++
    "    clear directions next to the object code saying where to find the\n"++
    "    Corresponding Source.  Regardless of what server hosts the\n"++
    "    Corresponding Source, you remain obligated to ensure that it is\n"++
    "    available for as long as needed to satisfy these requirements.\n"++
    "\n"++
    "    e) Convey the object code using peer-to-peer transmission, provided\n"++
    "    you inform other peers where the object code and Corresponding\n"++
    "    Source of the work are being offered to the general public at no\n"++
    "    charge under subsection 6d.\n"++
    "\n"++
    "  A separable portion of the object code, whose source code is excluded\n"++
    "from the Corresponding Source as a System Library, need not be\n"++
    "included in conveying the object code work.\n"++
    "\n"++
    "  A \"User Product\" is either (1) a \"consumer product\", which means any\n"++
    "tangible personal property which is normally used for personal, family,\n"++
    "or household purposes, or (2) anything designed or sold for incorporation\n"++
    "into a dwelling.  In determining whether a product is a consumer product,\n"++
    "doubtful cases shall be resolved in favor of coverage.  For a particular\n"++
    "product received by a particular user, \"normally used\" refers to a\n"++
    "typical or common use of that class of product, regardless of the status\n"++
    "of the particular user or of the way in which the particular user\n"++
    "actually uses, or expects or is expected to use, the product.  A product\n"++
    "is a consumer product regardless of whether the product has substantial\n"++
    "commercial, industrial or non-consumer uses, unless such uses represent\n"++
    "the only significant mode of use of the product.\n"++
    "\n"++
    "  \"Installation Information\" for a User Product means any methods,\n"++
    "procedures, authorization keys, or other information required to install\n"++
    "and execute modified versions of a covered work in that User Product from\n"++
    "a modified version of its Corresponding Source.  The information must\n"++
    "suffice to ensure that the continued functioning of the modified object\n"++
    "code is in no case prevented or interfered with solely because\n"++
    "modification has been made.\n"++
    "\n"++
    "  If you convey an object code work under this section in, or with, or\n"++
    "specifically for use in, a User Product, and the conveying occurs as\n"++
    "part of a transaction in which the right of possession and use of the\n"++
    "User Product is transferred to the recipient in perpetuity or for a\n"++
    "fixed term (regardless of how the transaction is characterized), the\n"++
    "Corresponding Source conveyed under this section must be accompanied\n"++
    "by the Installation Information.  But this requirement does not apply\n"++
    "if neither you nor any third party retains the ability to install\n"++
    "modified object code on the User Product (for example, the work has\n"++
    "been installed in ROM).\n"++
    "\n"++
    "  The requirement to provide Installation Information does not include a\n"++
    "requirement to continue to provide support service, warranty, or updates\n"++
    "for a work that has been modified or installed by the recipient, or for\n"++
    "the User Product in which it has been modified or installed.  Access to a\n"++
    "network may be denied when the modification itself materially and\n"++
    "adversely affects the operation of the network or violates the rules and\n"++
    "protocols for communication across the network.\n"++
    "\n"++
    "  Corresponding Source conveyed, and Installation Information provided,\n"++
    "in accord with this section must be in a format that is publicly\n"++
    "documented (and with an implementation available to the public in\n"++
    "source code form), and must require no special password or key for\n"++
    "unpacking, reading or copying.\n"++
    "\n"++
    "  7. Additional Terms.\n"++
    "\n"++
    "  \"Additional permissions\" are terms that supplement the terms of this\n"++
    "License by making exceptions from one or more of its conditions.\n"++
    "Additional permissions that are applicable to the entire Program shall\n"++
    "be treated as though they were included in this License, to the extent\n"++
    "that they are valid under applicable law.  If additional permissions\n"++
    "apply only to part of the Program, that part may be used separately\n"++
    "under those permissions, but the entire Program remains governed by\n"++
    "this License without regard to the additional permissions.\n"++
    "\n"++
    "  When you convey a copy of a covered work, you may at your option\n"++
    "remove any additional permissions from that copy, or from any part of\n"++
    "it.  (Additional permissions may be written to require their own\n"++
    "removal in certain cases when you modify the work.)  You may place\n"++
    "additional permissions on material, added by you to a covered work,\n"++
    "for which you have or can give appropriate copyright permission.\n"++
    "\n"++
    "  Notwithstanding any other provision of this License, for material you\n"++
    "add to a covered work, you may (if authorized by the copyright holders of\n"++
    "that material) supplement the terms of this License with terms:\n"++
    "\n"++
    "    a) Disclaiming warranty or limiting liability differently from the\n"++
    "    terms of sections 15 and 16 of this License; or\n"++
    "\n"++
    "    b) Requiring preservation of specified reasonable legal notices or\n"++
    "    author attributions in that material or in the Appropriate Legal\n"++
    "    Notices displayed by works containing it; or\n"++
    "\n"++
    "    c) Prohibiting misrepresentation of the origin of that material, or\n"++
    "    requiring that modified versions of such material be marked in\n"++
    "    reasonable ways as different from the original version; or\n"++
    "\n"++
    "    d) Limiting the use for publicity purposes of names of licensors or\n"++
    "    authors of the material; or\n"++
    "\n"++
    "    e) Declining to grant rights under trademark law for use of some\n"++
    "    trade names, trademarks, or service marks; or\n"++
    "\n"++
    "    f) Requiring indemnification of licensors and authors of that\n"++
    "    material by anyone who conveys the material (or modified versions of\n"++
    "    it) with contractual assumptions of liability to the recipient, for\n"++
    "    any liability that these contractual assumptions directly impose on\n"++
    "    those licensors and authors.\n"++
    "\n"++
    "  All other non-permissive additional terms are considered \"further\n"++
    "restrictions\" within the meaning of section 10.  If the Program as you\n"++
    "received it, or any part of it, contains a notice stating that it is\n"++
    "governed by this License along with a term that is a further\n"++
    "restriction, you may remove that term.  If a license document contains\n"++
    "a further restriction but permits relicensing or conveying under this\n"++
    "License, you may add to a covered work material governed by the terms\n"++
    "of that license document, provided that the further restriction does\n"++
    "not survive such relicensing or conveying.\n"++
    "\n"++
    "  If you add terms to a covered work in accord with this section, you\n"++
    "must place, in the relevant source files, a statement of the\n"++
    "additional terms that apply to those files, or a notice indicating\n"++
    "where to find the applicable terms.\n"++
    "\n"++
    "  Additional terms, permissive or non-permissive, may be stated in the\n"++
    "form of a separately written license, or stated as exceptions;\n"++

    "  8. Termination.\n"++
    "\n"++
    "  You may not propagate or modify a covered work except as expressly\n"++
    "provided under this License.  Any attempt otherwise to propagate or\n"++
    "modify it is void, and will automatically terminate your rights under\n"++
    "this License (including any patent licenses granted under the third\n"++
    "paragraph of section 11).\n"++
    "\n"++
    "  However, if you cease all violation of this License, then your\n"++
    "license from a particular copyright holder is reinstated (a)\n"++
    "provisionally, unless and until the copyright holder explicitly and\n"++
    "finally terminates your license, and (b) permanently, if the copyright\n"++
    "holder fails to notify you of the violation by some reasonable means\n"++
    "prior to 60 days after the cessation.\n"++
    "\n"++
    "  Moreover, your license from a particular copyright holder is\n"++
    "reinstated permanently if the copyright holder notifies you of the\n"++
    "violation by some reasonable means, this is the first time you have\n"++
    "received notice of violation of this License (for any work) from that\n"++
    "copyright holder, and you cure the violation prior to 30 days after\n"++
    "your receipt of the notice.\n"++
    "\n"++
    "  Termination of your rights under this section does not terminate the\n"++
    "licenses of parties who have received copies or rights from you under\n"++
    "this License.  If your rights have been terminated and not permanently\n"++
    "reinstated, you do not qualify to receive new licenses for the same\n"++
    "material under section 10.\n"++
    "\n"++
    "  9. Acceptance Not Required for Having Copies.\n"++
    "\n"++
    "  You are not required to accept this License in order to receive or\n"++
    "run a copy of the Program.  Ancillary propagation of a covered work\n"++
    "occurring solely as a consequence of using peer-to-peer transmission\n"++
    "to receive a copy likewise does not require acceptance.  However,\n"++
    "nothing other than this License grants you permission to propagate or\n"++
    "modify any covered work.  These actions infringe copyright if you do\n"++
    "not accept this License.  Therefore, by modifying or propagating a\n"++
    "covered work, you indicate your acceptance of this License to do so.\n"++
    "\n"++
    "  10. Automatic Licensing of Downstream Recipients.\n"++
    "\n"++
    "  Each time you convey a covered work, the recipient automatically\n"++
    "receives a license from the original licensors, to run, modify and\n"++
    "propagate that work, subject to this License.  You are not responsible\n"++
    "for enforcing compliance by third parties with this License.\n"++
    "\n"++
    "  An \"entity transaction\" is a transaction transferring control of an\n"++
    "organization, or substantially all assets of one, or subdividing an\n"++
    "organization, or merging organizations.  If propagation of a covered\n"++
    "work results from an entity transaction, each party to that\n"++
    "transaction who receives a copy of the work also receives whatever\n"++
    "licenses to the work the party's predecessor in interest had or could\n"++
    "give under the previous paragraph, plus a right to possession of the\n"++
    "Corresponding Source of the work from the predecessor in interest, if\n"++
    "the predecessor has it or can get it with reasonable efforts.\n"++
    "\n"++
    "  You may not impose any further restrictions on the exercise of the\n"++
    "rights granted or affirmed under this License.  For example, you may\n"++
    "not impose a license fee, royalty, or other charge for exercise of\n"++
    "rights granted under this License, and you may not initiate litigation\n"++
    "(including a cross-claim or counterclaim in a lawsuit) alleging that\n"++
    "any patent claim is infringed by making, using, selling, offering for\n"++
    "sale, or importing the Program or any portion of it.\n"++
    "\n"++
    "  11. Patents.\n"++
    "\n"++
    "  A \"contributor\" is a copyright holder who authorizes use under this\n"++
    "License of the Program or a work on which the Program is based.  The\n"++
    "work thus licensed is called the contributor's \"contributor version\".\n"++
    "\n"++
    "  A contributor's \"essential patent claims\" are all patent claims\n"++
    "owned or controlled by the contributor, whether already acquired or\n"++
    "hereafter acquired, that would be infringed by some manner, permitted\n"++
    "by this License, of making, using, or selling its contributor version,\n"++
    "but do not include claims that would be infringed only as a\n"++
    "consequence of further modification of the contributor version.  For\n"++
    "purposes of this definition, \"control\" includes the right to grant\n"++
    "patent sublicenses in a manner consistent with the requirements of\n"++
    "this License.\n"++
    "\n"++
    "  Each contributor grants you a non-exclusive, worldwide, royalty-free\n"++
    "patent license under the contributor's essential patent claims, to\n"++
    "make, use, sell, offer for sale, import and otherwise run, modify and\n"++
    "propagate the contents of its contributor version.\n"++
    "\n"++
    "  In the following three paragraphs, a \"patent license\" is any express\n"++
    "agreement or commitment, however denominated, not to enforce a patent\n"++
    "(such as an express permission to practice a patent or covenant not to\n"++
    "sue for patent infringement).  To \"grant\" such a patent license to a\n"++
    "party means to make such an agreement or commitment not to enforce a\n"++
    "patent against the party.\n"++
    "\n"++
    "  If you convey a covered work, knowingly relying on a patent license,\n"++
    "and the Corresponding Source of the work is not available for anyone\n"++
    "to copy, free of charge and under the terms of this License, through a\n"++
    "publicly available network server or other readily accessible means,\n"++
    "then you must either (1) cause the Corresponding Source to be so\n"++
    "available, or (2) arrange to deprive yourself of the benefit of the\n"++
    "patent license for this particular work, or (3) arrange, in a manner\n"++
    "consistent with the requirements of this License, to extend the patent\n"++
    "license to downstream recipients.  \"Knowingly relying\" means you have\n"++
    "actual knowledge that, but for the patent license, your conveying the\n"++
    "covered work in a country, or your recipient's use of the covered work\n"++
    "in a country, would infringe one or more identifiable patents in that\n"++
    "country that you have reason to believe are valid.\n"++
    "\n"++
    "  If, pursuant to or in connection with a single transaction or\n"++
    "arrangement, you convey, or propagate by procuring conveyance of, a\n"++
    "covered work, and grant a patent license to some of the parties\n"++
    "receiving the covered work authorizing them to use, propagate, modify\n"++
    "or convey a specific copy of the covered work, then the patent license\n"++
    "you grant is automatically extended to all recipients of the covered\n"++
    "work and works based on it.\n"++
    "\n"++
    "  A patent license is \"discriminatory\" if it does not include within\n"++
    "the scope of its coverage, prohibits the exercise of, or is\n"++
    "conditioned on the non-exercise of one or more of the rights that are\n"++
    "specifically granted under this License.  You may not convey a covered\n"++
    "work if you are a party to an arrangement with a third party that is\n"++
    "in the business of distributing software, under which you make payment\n"++
    "to the third party based on the extent of your activity of conveying\n"++
    "the work, and under which the third party grants, to any of the\n"++
    "parties who would receive the covered work from you, a discriminatory\n"++
    "patent license (a) in connection with copies of the covered work\n"++
    "conveyed by you (or copies made from those copies), or (b) primarily\n"++
    "for and in connection with specific products or compilations that\n"++
    "contain the covered work, unless you entered into that arrangement,\n"++
    "or that patent license was granted, prior to 28 March 2007.\n"++
    "\n"++
    "  Nothing in this License shall be construed as excluding or limiting\n"++
    "any implied license or other defenses to infringement that may\n"++
    "otherwise be available to you under applicable patent law.\n"++
    "\n"++
    "  12. No Surrender of Others' Freedom.\n"++
    "\n"++
    "  If conditions are imposed on you (whether by court order, agreement or\n"++
    "otherwise) that contradict the conditions of this License, they do not\n"++
    "excuse you from the conditions of this License.  If you cannot convey a\n"++
    "covered work so as to satisfy simultaneously your obligations under this\n"++
    "License and any other pertinent obligations, then as a consequence you may\n"++
    "not convey it at all.  For example, if you agree to terms that obligate you\n"++
    "to collect a royalty for further conveying from those to whom you convey\n"++
    "the Program, the only way you could satisfy both those terms and this\n"++
    "License would be to refrain entirely from conveying the Program.\n"++
    "\n"++
    "  13. Use with the GNU Affero General Public License.\n"++
    "\n"++
    "  Notwithstanding any other provision of this License, you have\n"++
    "permission to link or combine any covered work with a work licensed\n"++
    "under version 3 of the GNU Affero General Public License into a single\n"++
    "combined work, and to convey the resulting work.  The terms of this\n"++
    "License will continue to apply to the part which is the covered work,\n"++
    "but the special requirements of the GNU Affero General Public License,\n"++
    "section 13, concerning interaction through a network will apply to the\n"++
    "combination as such.\n"++

    "  14. Revised Versions of this License.\n"++
    "\n"++
    "  The Free Software Foundation may publish revised and/or new versions of\n"++
    "the GNU General Public License from time to time.  Such new versions will\n"++
    "be similar in spirit to the present version, but may differ in detail to\n"++
    "address new problems or concerns.\n"++
    "\n"++
    "  Each version is given a distinguishing version number.  If the\n"++
    "Program specifies that a certain numbered version of the GNU General\n"++
    "Public License \"or any later version\" applies to it, you have the\n"++
    "option of following the terms and conditions either of that numbered\n"++
    "version or of any later version published by the Free Software\n"++
    "Foundation.  If the Program does not specify a version number of the\n"++
    "GNU General Public License, you may choose any version ever published\n"++
    "by the Free Software Foundation.\n"++
    "\n"++
    "  If the Program specifies that a proxy can decide which future\n"++
    "versions of the GNU General Public License can be used, that proxy's\n"++
    "public statement of acceptance of a version permanently authorizes you\n"++
    "to choose that version for the Program.\n"++
    "\n"++
    "  Later license versions may give you additional or different\n"++
    "permissions.  However, no additional obligations are imposed on any\n"++
    "author or copyright holder as a result of your choosing to follow a\n"++
    "later version.\n"++
    "\n"++
    "  15. Disclaimer of Warranty.\n"++
    "\n"++
    "  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY\n"++
