-    "\n"
-    " Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>\n"
-    " Everyone is permitted to copy and distribute verbatim copies\n"
-    " of this license document, but changing it is not allowed.\n"
-    "\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"

-    "\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"

-    "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"

-    "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"

-    "  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"

-    "  If you add terms to a covered work in accord with this section, you\n"

-    "  Additional terms, permissive or non-permissive, may be stated in the\n"
-    "form of a separately written license, or stated as exceptions;\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"

-    "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"

-    "received notice of violation of this License (for any work) from that\n"

-    "your receipt of the notice.\n"
-    "\n"
-    "  Termination of your rights under this section does not terminate the\n"

-    "\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"

-    "\n"
-    "  Each time you convey a covered work, the recipient automatically\n"
-    "receives a license from the original licensors, to run, modify and\n"

-    "  An \"entity transaction\" is a transaction transferring control of 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"

-    "\n"
-    "  A \"contributor\" is a copyright holder who authorizes use under this\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"
