 // terms of section 4, provided that you also meet all of these conditions:  
 //  
 //     a) The work must carry prominent notices stating that you modified  
 //     it, and giving a relevant date.  
 //  
 //     b) The work must carry prominent notices stating that it is  
 //     released under this License and any conditions added under section  
 //     7.  This requirement modifies the requirement in section 4 to  
 //     "keep intact all notices".  
 //  
 //     c) You must license the entire work, as a whole, under this  
 //     License to anyone who comes into possession of a copy.  This  
 //     License will therefore apply, along with any applicable section 7  
 //     additional terms, to the whole of the work, and all its parts,  
 //     regardless of how they are packaged.  This License gives no  
 //     permission to license the work in any other way, but it does not  
 //     invalidate such permission if you have separately received it.  
 //  
 //     d) If the work has interactive user interfaces, each must display  
 //     Appropriate Legal Notices; however, if the Program has interactive  
 //     interfaces that do not display Appropriate Legal Notices, your  
 //     work need not make them do so.  
 //  
 //   A compilation of a covered work with other separate and independent  
 // works, which are not by their nature extensions of the covered work,  
 // and which are not combined with it such as to form a larger program,  
 // in or on a volume of a storage or distribution medium, is called an  
 // "aggregate" if the compilation and its resulting copyright are not  
 // used to limit the access or legal rights of the compilation's users  
 // beyond what the individual works permit.  Inclusion of a covered work  
 // in an aggregate does not cause this License to apply to the other  
 // parts of the aggregate.  
 //  
 //   6. Conveying Non-Source Forms.  
 //  
 //   You may convey a covered work in object code form under the terms  
 // of sections 4 and 5, provided that you also convey the  
 // machine-readable Corresponding Source under the terms of this License,  
 // in one of these ways:  
 //  
 //     a) Convey the object code in, or embodied in, a physical product  
 //     (including a physical distribution medium), accompanied by the  
 //     Corresponding Source fixed on a durable physical medium  
 //     customarily used for software interchange.  
 //  
 //     b) Convey the object code in, or embodied in, a physical product  
 //     (including a physical distribution medium), accompanied by a  
 //     written offer, valid for at least three years and valid for as  
 //     long as you offer spare parts or customer support for that product  
 //     model, to give anyone who possesses the object code either (1) a  
 //     copy of the Corresponding Source for all the software in the  
 //     product that is covered by this License, on a durable physical  
 //     medium customarily used for software interchange, for a price no  
 //     more than your reasonable cost of physically performing this  
 //     conveying of source, or (2) access to copy the  
 //     Corresponding Source from a network server at no charge.  
 //  
 //     c) Convey individual copies of the object code with a copy of the  
 //     written offer to provide the Corresponding Source.  This  
 //     alternative is allowed only occasionally and noncommercially, and  
 //     only if you received the object code with such an offer, in accord  
 //     with subsection 6b.  
 //  
 //     d) Convey the object code by offering access from a designated  
 //     place (gratis or for a charge), and offer equivalent access to the  
 //     Corresponding Source in the same way through the same place at no  
 //     further charge.  You need not require recipients to copy the  
 //     Corresponding Source along with the object code.  If the place to  
 //     copy the object code is a network server, the Corresponding Source  
 //     may be on a different server (operated by you or a third party)  
 //     that supports equivalent copying facilities, provided you maintain  
 //     clear directions next to the object code saying where to find the  
 //     Corresponding Source.  Regardless of what server hosts the  
 //     Corresponding Source, you remain obligated to ensure that it is  
 //     available for as long as needed to satisfy these requirements.  
 //  
 //     e) Convey the object code using peer-to-peer transmission, provided  
 //     you inform other peers where the object code and Corresponding  
 //     Source of the work are being offered to the general public at no  
 //     charge under subsection 6d.  
 //  
 //   A separable portion of the object code, whose source code is excluded  
 // from the Corresponding Source as a System Library, need not be  
 // included in conveying the object code work.  
 //  
 //   A "User Product" is either (1) a "consumer product", which means any  
 // tangible personal property which is normally used for personal, family,  
 // or household purposes, or (2) anything designed or sold for incorporation  
 // into a dwelling.  In determining whether a product is a consumer product,  
 // doubtful cases shall be resolved in favor of coverage.  For a particular  
 // product received by a particular user, "normally used" refers to a  
 // typical or common use of that class of product, regardless of the status  
 // of the particular user or of the way in which the particular user  
 // actually uses, or expects or is expected to use, the product.  A product  
 // is a consumer product regardless of whether the product has substantial  
 // commercial, industrial or non-consumer uses, unless such uses represent  
 // the only significant mode of use of the product.  
 //  
 //   "Installation Information" for a User Product means any methods,  
 // procedures, authorization keys, or other information required to install  
 // and execute modified versions of a covered work in that User Product from  
 // a modified version of its Corresponding Source.  The information must  
 // suffice to ensure that the continued functioning of the modified object  
 // code is in no case prevented or interfered with solely because  
 // modification has been made.  
 //  
 //   If you convey an object code work under this section in, or with, or  
 // specifically for use in, a User Product, and the conveying occurs as  
 // part of a transaction in which the right of possession and use of the  
 // User Product is transferred to the recipient in perpetuity or for a  
 // fixed term (regardless of how the transaction is characterized), the  
 // Corresponding Source conveyed under this section must be accompanied  
 // by the Installation Information.  But this requirement does not apply  
 // if neither you nor any third party retains the ability to install  
 // modified object code on the User Product (for example, the work has  
 // been installed in ROM).  
 //  
 //   The requirement to provide Installation Information does not include a  
 // requirement to continue to provide support service, warranty, or updates  
 // for a work that has been modified or installed by the recipient, or for  
 // the User Product in which it has been modified or installed.  Access to a  
 // network may be denied when the modification itself materially and  
 // adversely affects the operation of the network or violates the rules and  
 // protocols for communication across the network.  
 //  
 //   Corresponding Source conveyed, and Installation Information provided,  
 // in accord with this section must be in a format that is publicly  
 // documented (and with an implementation available to the public in  
 // source code form), and must require no special password or key for  
 // unpacking, reading or copying.  
 //  
 //   7. Additional Terms.  
 //  
 //   "Additional permissions" are terms that supplement the terms of this  
 // License by making exceptions from one or more of its conditions.  
 // Additional permissions that are applicable to the entire Program shall  
 // be treated as though they were included in this License, to the extent  
 // that they are valid under applicable law.  If additional permissions  
 // apply only to part of the Program, that part may be used separately  
 // under those permissions, but the entire Program remains governed by  
 // this License without regard to the additional permissions.  
 //  
 //   When you convey a copy of a covered work, you may at your option  
 // remove any additional permissions from that copy, or from any part of  
 // it.  (Additional permissions may be written to require their own  
 // removal in certain cases when you modify the work.)  You may place  
 // additional permissions on material, added by you to a covered work,  
 // for which you have or can give appropriate copyright permission.  
 //  
 //   Notwithstanding any other provision of this License, for material you  
 // add to a covered work, you may (if authorized by the copyright holders of  
 // that material) supplement the terms of this License with terms:  
 //  
 //     a) Disclaiming warranty or limiting liability differently from the  
 //     terms of sections 15 and 16 of this License; or  
 //  
 //     b) Requiring preservation of specified reasonable legal notices or  
 //     author attributions in that material or in the Appropriate Legal  
 //     Notices displayed by works containing it; or  
 //  
 //     c) Prohibiting misrepresentation of the origin of that material, or  
 //     requiring that modified versions of such material be marked in  
 //     reasonable ways as different from the original version; or  
 //  
 //     d) Limiting the use for publicity purposes of names of licensors or  
 //     authors of the material; or  
 //  
 //     e) Declining to grant rights under trademark law for use of some  
 //     trade names, trademarks, or service marks; or  
 //  
 //     f) Requiring indemnification of licensors and authors of that  
 //     material by anyone who conveys the material (or modified versions of  
 //     it) with contractual assumptions of liability to the recipient, for  
 //     any liability that these contractual assumptions directly impose on  
 //     those licensors and authors.  
 //  
 //   All other non-permissive additional terms are considered "further  
 // restrictions" within the meaning of section 10.  If the Program as you  
 // received it, or any part of it, contains a notice stating that it is  
 // governed by this License along with a term that is a further  
 // restriction, you may remove that term.  If a license document contains  
 // a further restriction but permits relicensing or conveying under this  
 // License, you may add to a covered work material governed by the terms  
 // of that license document, provided that the further restriction does  
 // not survive such relicensing or conveying.  
 //  
 //   If you add terms to a covered work in accord with this section, you  
 // must place, in the relevant source files, a statement of the  
 // additional terms that apply to those files, or a notice indicating  
 // where to find the applicable terms.  
 //  
 //   Additional terms, permissive or non-permissive, may be stated in the  
 // form of a separately written license, or stated as exceptions;  
 // the above requirements apply either way.  
 //  
 //   8. Termination.  
 //  
 //   You may not propagate or modify a covered work except as expressly  
 // provided under this License.  Any attempt otherwise to propagate or  
 // modify it is void, and will automatically terminate your rights under  
 // this License (including any patent licenses granted under the third  
 // paragraph of section 11).  
 //  
 //   However, if you cease all violation of this License, then your  
 // license from a particular copyright holder is reinstated (a)  
 // provisionally, unless and until the copyright holder explicitly and  
 // finally terminates your license, and (b) permanently, if the copyright  
 // holder fails to notify you of the violation by some reasonable means  
 // prior to 60 days after the cessation.  
 //  
 //   Moreover, your license from a particular copyright holder is  
 // reinstated permanently if the copyright holder notifies you of the  
 // violation by some reasonable means, this is the first time you have  
 // received notice of violation of this License (for any work) from that  
 // copyright holder, and you cure the violation prior to 30 days after  
 // your receipt of the notice.  
 //  
 //   Termination of your rights under this section does not terminate the  
 // licenses of parties who have received copies or rights from you under  
 // this License.  If your rights have been terminated and not permanently  
 // reinstated, you do not qualify to receive new licenses for the same  
 // material under section 10.  
 //  
 //   9. Acceptance Not Required for Having Copies.  
 //  
 //   You are not required to accept this License in order to receive or  
 // run a copy of the Program.  Ancillary propagation of a covered work  
 // occurring solely as a consequence of using peer-to-peer transmission  
 // to receive a copy likewise does not require acceptance.  However,  
 // nothing other than this License grants you permission to propagate or  
 // modify any covered work.  These actions infringe copyright if you do  
 // not accept this License.  Therefore, by modifying or propagating a  
 // covered work, you indicate your acceptance of this License to do so.  
 //  
 //   10. Automatic Licensing of Downstream Recipients.  
 //  
 //   Each time you convey a covered work, the recipient automatically  
 // receives a license from the original licensors, to run, modify and  
 // propagate that work, subject to this License.  You are not responsible  
 // for enforcing compliance by third parties with this License.  
 //  
 //   An "entity transaction" is a transaction transferring control of an  
 // organization, or substantially all assets of one, or subdividing an  
 // organization, or merging organizations.  If propagation of a covered  
 // work results from an entity transaction, each party to that  
 // transaction who receives a copy of the work also receives whatever  
 // licenses to the work the party's predecessor in interest had or could  
 // give under the previous paragraph, plus a right to possession of the  
 // Corresponding Source of the work from the predecessor in interest, if  
 // the predecessor has it or can get it with reasonable efforts.  
 //  
 //   You may not impose any further restrictions on the exercise of the  
 // rights granted or affirmed under this License.  For example, you may  
 // not impose a license fee, royalty, or other charge for exercise of  
 // rights granted under this License, and you may not initiate litigation  
 // (including a cross-claim or counterclaim in a lawsuit) alleging that  
 // any patent claim is infringed by making, using, selling, offering for  
 // sale, or importing the Program or any portion of it.  
 //  
 //   11. Patents.  
 //  
 //   A "contributor" is a copyright holder who authorizes use under this  
 // License of the Program or a work on which the Program is based.  The  
 // work thus licensed is called the contributor's "contributor version".  
 //  
 //   A contributor's "essential patent claims" are all patent claims  
 // owned or controlled by the contributor, whether already acquired or  
 // hereafter acquired, that would be infringed by some manner, permitted  
 // by this License, of making, using, or selling its contributor version,  
 // but do not include claims that would be infringed only as a  
 // consequence of further modification of the contributor version.  For  
 // purposes of this definition, "control" includes the right to grant  
 // patent sublicenses in a manner consistent with the requirements of  
 // this License.  
 //  
 //   Each contributor grants you a non-exclusive, worldwide, royalty-free  
 // patent license under the contributor's essential patent claims, to  
 // make, use, sell, offer for sale, import and otherwise run, modify and  
 // propagate the contents of its contributor version.  
 //  
 //   In the following three paragraphs, a "patent license" is any express  
 // agreement or commitment, however denominated, not to enforce a patent  
 // (such as an express permission to practice a patent or covenant not to  
 // sue for patent infringement).  To "grant" such a patent license to a  
 // party means to make such an agreement or commitment not to enforce a  
 // patent against the party.  
 //  
 //   If you convey a covered work, knowingly relying on a patent license,  
 // and the Corresponding Source of the work is not available for anyone  
 // to copy, free of charge and under the terms of this License, through a  
 // publicly available network server or other readily accessible means,  
 // then you must either (1) cause the Corresponding Source to be so  
 // available, or (2) arrange to deprive yourself of the benefit of the  
 // patent license for this particular work, or (3) arrange, in a manner  
 // consistent with the requirements of this License, to extend the patent  
 // license to downstream recipients.  "Knowingly relying" means you have  
 // actual knowledge that, but for the patent license, your conveying the  
 // covered work in a country, or your recipient's use of the covered work  
 // in a country, would infringe one or more identifiable patents in that  
 // country that you have reason to believe are valid.  
 //  
 //   If, pursuant to or in connection with a single transaction or  
 // arrangement, you convey, or propagate by procuring conveyance of, a  
 // covered work, and grant a patent license to some of the parties  
 // receiving the covered work authorizing them to use, propagate, modify  
 // or convey a specific copy of the covered work, then the patent license  
 // you grant is automatically extended to all recipients of the covered  
 // work and works based on it.  
 //  
 //  A patent license is "discriminatory" if it does not include within  
 // the scope of its coverage, prohibits the exercise of, or is  
 // conditioned on the non-exercise of one or more of the rights that are  
 // specifically granted under this License.  You may not convey a covered  
 // work if you are a party to an arrangement with a third party that is  
 // in the business of distributing software, under which you make payment  
 // to the third party based on the extent of your activity of conveying  
 // the work, and under which the third party grants, to any of the  
 // parties who would receive the covered work from you, a discriminatory  
 // patent license (a) in connection with copies of the covered work  
 // conveyed by you (or copies made from those copies), or (b) primarily  
 // for and in connection with specific products or compilations that  
 // contain the covered work, unless you entered into that arrangement,  
 // or that patent license was granted, prior to 28 March 2007.  
 //  
 //   Nothing in this License shall be construed as excluding or limiting  
 // any implied license or other defenses to infringement that may  
 // otherwise be available to you under applicable patent law.  
 //  
 //   12. No Surrender of Others' Freedom.  
 //  
 //   If conditions are imposed on you (whether by court order, agreement or  
 // otherwise) that contradict the conditions of this License, they do not  
 // excuse you from the conditions of this License.  If you cannot convey a  
 // covered work so as to satisfy simultaneously your obligations under this  
 // License and any other pertinent obligations, then as a consequence you may  
 // not convey it at all.  For example, if you agree to terms that obligate you  
 // to collect a royalty for further conveying from those to whom you convey  
 // the Program, the only way you could satisfy both those terms and this  
 // License would be to refrain entirely from conveying the Program.  
 //  
 //   13. Use with the GNU Affero General Public License.  
 //  
 //   Notwithstanding any other provision of this License, you have  
 // permission to link or combine any covered work with a work licensed  
 // under version 3 of the GNU Affero General Public License into a single  
 // combined work, and to convey the resulting work.  The terms of this  
 // License will continue to apply to the part which is the covered work,  
 // but the special requirements of the GNU Affero General Public License,  
 // section 13, concerning interaction through a network will apply to the  
 // combination as such.  
 //  
 //   14. Revised Versions of this License.  
 //  
 //   The Free Software Foundation may publish revised and/or new versions of  
 // the GNU General Public License from time to time.  Such new versions will  
 // be similar in spirit to the present version, but may differ in detail to  
 // address new problems or concerns.  
 //  
 //   Each version is given a distinguishing version number.  If the  
 // Program specifies that a certain numbered version of the GNU General  
 // Public License "or any later version" applies to it, you have the  
 // option of following the terms and conditions either of that numbered  
 // version or of any later version published by the Free Software  
 // Foundation.  If the Program does not specify a version number of the  
 // GNU General Public License, you may choose any version ever published  
 // by the Free Software Foundation.  
 //  
 //   If the Program specifies that a proxy can decide which future  
 // versions of the GNU General Public License can be used, that proxy's  
 // public statement of acceptance of a version permanently authorizes you  
 // to choose that version for the Program.  
 //  
 //   Later license versions may give you additional or different  
 // permissions.  However, no additional obligations are imposed on any  
 // author or copyright holder as a result of your choosing to follow a  
 // later version.  
 //  
 //   15. Disclaimer of Warranty.  
 //  
 //   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY  
 // APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT  
 // HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY  
 // OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,  
 // THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR  
 // PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM  
 // IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF  
 // ALL NECESSARY SERVICING, REPAIR OR CORRECTION.  
 //  
 //   16. Limitation of Liability.  
 //  
 //   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING  
 // WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS  
 // THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY  
 // GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE  
 // USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF  
 // DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD  
 // PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),  
 // EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF  
 // SUCH DAMAGES.  
 //  
 //   17. Interpretation of Sections 15 and 16.  
 //  
 //   If the disclaimer of warranty and limitation of liability provided  
 // above cannot be given local legal effect according to their terms,  
 // reviewing courts shall apply local law that most closely approximates  
 // an absolute waiver of all civil liability in connection with the  
 // Program, unless a warranty or assumption of liability accompanies a  
 // copy of the Program in return for a fee.
