1675                     GNU GENERAL PUBLIC LICENSE

  1676                        Version 3, 29 June 2007

  1677 

  1678  Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>

  1679  Everyone is permitted to copy and distribute verbatim copies

  1680  of this license document, but changing it is not allowed.

  1681 

  1682                             Preamble

  1683 

  1684   The GNU General Public License is a free, copyleft license for

  1685 software and other kinds of works.

  1686 

  1687   The licenses for most software and other practical works are designed

  1688 to take away your freedom to share and change the works.  By contrast,

  1689 the GNU General Public License is intended to guarantee your freedom to

  1690 share and change all versions of a program--to make sure it remains free

  1691 software for all its users.  We, the Free Software Foundation, use the

  1692 GNU General Public License for most of our software; it applies also to

  1693 any other work released this way by its authors.  You can apply it to

  1694 your programs, too.

  1695 

  1696   When we speak of free software, we are referring to freedom, not

  1697 price.  Our General Public Licenses are designed to make sure that you

  1698 have the freedom to distribute copies of free software (and charge for

  1699 them if you wish), that you receive source code or can get it if you

  1700 want it, that you can change the software or use pieces of it in new

  1701 free programs, and that you know you can do these things.

  1702 

  1703   To protect your rights, we need to prevent others from denying you

  1704 these rights or asking you to surrender the rights.  Therefore, you have

  1705 certain responsibilities if you distribute copies of the software, or if

  1706 you modify it: responsibilities to respect the freedom of others.

  1707 

  1708   For example, if you distribute copies of such a program, whether

  1709 gratis or for a fee, you must pass on to the recipients the same

  1710 freedoms that you received.  You must make sure that they, too, receive

  1711 or can get the source code.  And you must show them these terms so they

  1712 know their rights.

  1713 

  1714   Developers that use the GNU GPL protect your rights with two steps:

  1715 (1) assert copyright on the software, and (2) offer you this License

  1716 giving you legal permission to copy, distribute and/or modify it.

  1717 

  1718   For the developers' and authors' protection, the GPL clearly explains

  1719 that there is no warranty for this free software.  For both users' and

  1720 authors' sake, the GPL requires that modified versions be marked as

  1721 changed, so that their problems will not be attributed erroneously to

  1722 authors of previous versions.

  1723 

  1724   Some devices are designed to deny users access to install or run

  1725 modified versions of the software inside them, although the manufacturer

  1726 can do so.  This is fundamentally incompatible with the aim of

  1727 protecting users' freedom to change the software.  The systematic

  1728 pattern of such abuse occurs in the area of products for individuals to

  1729 use, which is precisely where it is most unacceptable.  Therefore, we

  1730 have designed this version of the GPL to prohibit the practice for those

  1731 products.  If such problems arise substantially in other domains, we

  1732 stand ready to extend this provision to those domains in future versions

  1733 of the GPL, as needed to protect the freedom of users.

  1734 

  1735   Finally, every program is threatened constantly by software patents.

  1736 States should not allow patents to restrict development and use of

  1737 software on general-purpose computers, but in those that do, we wish to

  1738 avoid the special danger that patents applied to a free program could

  1739 make it effectively proprietary.  To prevent this, the GPL assures that

  1740 patents cannot be used to render the program non-free.

  1741 

  1742   The precise terms and conditions for copying, distribution and

  1743 modification follow.

  1744 

  1745                        TERMS AND CONDITIONS

  1746 

  1747   0. Definitions.

  1748 

  1749   "This License" refers to version 3 of the GNU General Public License.

  1750 

  1751   "Copyright" also means copyright-like laws that apply to other kinds of

  1752 works, such as semiconductor masks.

  1753 

  1754   "The Program" refers to any copyrightable work licensed under this

  1755 License.  Each licensee is addressed as "you".  "Licensees" and

  1756 "recipients" may be individuals or organizations.

  1757 

  1758   To "modify" a work means to copy from or adapt all or part of the work

  1759 in a fashion requiring copyright permission, other than the making of an

  1760 exact copy.  The resulting work is called a "modified version" of the

  1761 earlier work or a work "based on" the earlier work.

  1762 

  1763   A "covered work" means either the unmodified Program or a work based

  1764 on the Program.

  1765 

  1766   To "propagate" a work means to do anything with it that, without

  1767 permission, would make you directly or secondarily liable for

  1768 infringement under applicable copyright law, except executing it on a

  1769 computer or modifying a private copy.  Propagation includes copying,

  1770 distribution (with or without modification), making available to the

  1771 public, and in some countries other activities as well.

  1772 

  1773   To "convey" a work means any kind of propagation that enables other

  1774 parties to make or receive copies.  Mere interaction with a user through

  1775 a computer network, with no transfer of a copy, is not conveying.

  1776 

  1777   An interactive user interface displays "Appropriate Legal Notices"

  1778 to the extent that it includes a convenient and prominently visible

  1779 feature that (1) displays an appropriate copyright notice, and (2)

  1780 tells the user that there is no warranty for the work (except to the

  1781 extent that warranties are provided), that licensees may convey the

  1782 work under this License, and how to view a copy of this License.  If

  1783 the interface presents a list of user commands or options, such as a

  1784 menu, a prominent item in the list meets this criterion.

  1785 

  1786   1. Source Code.

  1787 

  1788   The "source code" for a work means the preferred form of the work

  1789 for making modifications to it.  "Object code" means any non-source

  1790 form of a work.

  1791 

  1792   A "Standard Interface" means an interface that either is an official

  1793 standard defined by a recognized standards body, or, in the case of

  1794 interfaces specified for a particular programming language, one that

  1795 is widely used among developers working in that language.

  1796 

  1797   The "System Libraries" of an executable work include anything, other

  1798 than the work as a whole, that (a) is included in the normal form of

  1799 packaging a Major Component, but which is not part of that Major

  1800 Component, and (b) serves only to enable use of the work with that

  1801 Major Component, or to implement a Standard Interface for which an

  1802 implementation is available to the public in source code form.  A

  1803 "Major Component", in this context, means a major essential component

  1804 (kernel, window system, and so on) of the specific operating system

  1805 (if any) on which the executable work runs, or a compiler used to

  1806 produce the work, or an object code interpreter used to run it.

  1807 

  1808   The "Corresponding Source" for a work in object code form means all

  1809 the source code needed to generate, install, and (for an executable

  1810 work) run the object code and to modify the work, including scripts to

  1811 control those activities.  However, it does not include the work's

  1812 System Libraries, or general-purpose tools or generally available free

  1813 programs which are used unmodified in performing those activities but

  1814 which are not part of the work.  For example, Corresponding Source

  1815 includes interface definition files associated with source files for

  1816 the work, and the source code for shared libraries and dynamically

  1817 linked subprograms that the work is specifically designed to require,

  1818 such as by intimate data communication or control flow between those

  1819 subprograms and other parts of the work.

  1820 

  1821   The Corresponding Source need not include anything that users

  1822 can regenerate automatically from other parts of the Corresponding

  1823 Source.

  1824 

  1825   The Corresponding Source for a work in source code form is that

  1826 same work.

  1827 

  1828   2. Basic Permissions.

  1829 

  1830   All rights granted under this License are granted for the term of

  1831 copyright on the Program, and are irrevocable provided the stated

  1832 conditions are met.  This License explicitly affirms your unlimited

  1833 permission to run the unmodified Program.  The output from running a

  1834 covered work is covered by this License only if the output, given its

  1835 content, constitutes a covered work.  This License acknowledges your

  1836 rights of fair use or other equivalent, as provided by copyright law.

  1837 

  1838   You may make, run and propagate covered works that you do not

  1839 convey, without conditions so long as your license otherwise remains

  1840 in force.  You may convey covered works to others for the sole purpose

  1841 of having them make modifications exclusively for you, or provide you

  1842 with facilities for running those works, provided that you comply with

  1843 the terms of this License in conveying all material for which you do

  1844 not control copyright.  Those thus making or running the covered works

  1845 for you must do so exclusively on your behalf, under your direction

  1846 and control, on terms that prohibit them from making any copies of

  1847 your copyrighted material outside their relationship with you.

  1848 

  1849   Conveying under any other circumstances is permitted solely under

  1850 the conditions stated below.  Sublicensing is not allowed; section 10

  1851 makes it unnecessary.

  1852 

  1853   3. Protecting Users' Legal Rights From Anti-Circumvention Law.

  1854 

  1855   No covered work shall be deemed part of an effective technological

  1856 measure under any applicable law fulfilling obligations under article

  1857 11 of the WIPO copyright treaty adopted on 20 December 1996, or

  1858 similar laws prohibiting or restricting circumvention of such

  1859 measures.

  1860 

  1861   When you convey a covered work, you waive any legal power to forbid

  1862 circumvention of technological measures to the extent such circumvention

  1863 is effected by exercising rights under this License with respect to

  1864 the covered work, and you disclaim any intention to limit operation or

  1865 modification of the work as a means of enforcing, against the work's

  1866 users, your or third parties' legal rights to forbid circumvention of

  1867 technological measures.

  1868 

  1869   4. Conveying Verbatim Copies.

  1870 

  1871   You may convey verbatim copies of the Program's source code as you

  1872 receive it, in any medium, provided that you conspicuously and

  1873 appropriately publish on each copy an appropriate copyright notice;

  1874 keep intact all notices stating that this License and any

  1875 non-permissive terms added in accord with section 7 apply to the code;

  1876 keep intact all notices of the absence of any warranty; and give all

  1877 recipients a copy of this License along with the Program.

  1878 

  1879   You may charge any price or no price for each copy that you convey,

  1880 and you may offer support or warranty protection for a fee.

  1881 

  1882   5. Conveying Modified Source Versions.

  1883 

  1884   You may convey a work based on the Program, or the modifications to

  1885 produce it from the Program, in the form of source code under the

  1886 terms of section 4, provided that you also meet all of these conditions:

  1887 

  1888     a) The work must carry prominent notices stating that you modified

  1889     it, and giving a relevant date.

  1890 

  1891     b) The work must carry prominent notices stating that it is

  1892     released under this License and any conditions added under section

  1893     7.  This requirement modifies the requirement in section 4 to

  1894     "keep intact all notices".

  1895 

  1896     c) You must license the entire work, as a whole, under this

  1897     License to anyone who comes into possession of a copy.  This

  1898     License will therefore apply, along with any applicable section 7

  1899     additional terms, to the whole of the work, and all its parts,

  1900     regardless of how they are packaged.  This License gives no

  1901     permission to license the work in any other way, but it does not

  1902     invalidate such permission if you have separately received it.

  1903 

  1904     d) If the work has interactive user interfaces, each must display

  1905     Appropriate Legal Notices; however, if the Program has interactive

  1906     interfaces that do not display Appropriate Legal Notices, your

  1907     work need not make them do so.

  1908 

  1909   A compilation of a covered work with other separate and independent

  1910 works, which are not by their nature extensions of the covered work,

  1911 and which are not combined with it such as to form a larger program,

  1912 in or on a volume of a storage or distribution medium, is called an

  1913 "aggregate" if the compilation and its resulting copyright are not

  1914 used to limit the access or legal rights of the compilation's users

  1915 beyond what the individual works permit.  Inclusion of a covered work

  1916 in an aggregate does not cause this License to apply to the other

  1917 parts of the aggregate.

  1918 

  1919   6. Conveying Non-Source Forms.

  1920 

  1921   You may convey a covered work in object code form under the terms

  1922 of sections 4 and 5, provided that you also convey the

  1923 machine-readable Corresponding Source under the terms of this License,

  1924 in one of these ways:

  1925 

  1926     a) Convey the object code in, or embodied in, a physical product

  1927     (including a physical distribution medium), accompanied by the

  1928     Corresponding Source fixed on a durable physical medium

  1929     customarily used for software interchange.

  1930 

  1931     b) Convey the object code in, or embodied in, a physical product

  1932     (including a physical distribution medium), accompanied by a

  1933     written offer, valid for at least three years and valid for as

  1934     long as you offer spare parts or customer support for that product

  1935     model, to give anyone who possesses the object code either (1) a

  1936     copy of the Corresponding Source for all the software in the

  1937     product that is covered by this License, on a durable physical

  1938     medium customarily used for software interchange, for a price no

  1939     more than your reasonable cost of physically performing this

  1940     conveying of source, or (2) access to copy the

  1941     Corresponding Source from a network server at no charge.

  1942 

  1943     c) Convey individual copies of the object code with a copy of the

  1944     written offer to provide the Corresponding Source.  This

  1945     alternative is allowed only occasionally and noncommercially, and

  1946     only if you received the object code with such an offer, in accord

  1947     with subsection 6b.

  1948 

  1949     d) Convey the object code by offering access from a designated

  1950     place (gratis or for a charge), and offer equivalent access to the

  1951     Corresponding Source in the same way through the same place at no

  1952     further charge.  You need not require recipients to copy the

  1953     Corresponding Source along with the object code.  If the place to

  1954     copy the object code is a network server, the Corresponding Source

  1955     may be on a different server (operated by you or a third party)

  1956     that supports equivalent copying facilities, provided you maintain

  1957     clear directions next to the object code saying where to find the

  1958     Corresponding Source.  Regardless of what server hosts the

  1959     Corresponding Source, you remain obligated to ensure that it is

  1960     available for as long as needed to satisfy these requirements.

  1961 

  1962     e) Convey the object code using peer-to-peer transmission, provided

  1963     you inform other peers where the object code and Corresponding

  1964     Source of the work are being offered to the general public at no

  1965     charge under subsection 6d.

  1966 

  1967   A separable portion of the object code, whose source code is excluded

  1968 from the Corresponding Source as a System Library, need not be

  1969 included in conveying the object code work.

  1970 

  1971   A "User Product" is either (1) a "consumer product", which means any

  1972 tangible personal property which is normally used for personal, family,

  1973 or household purposes, or (2) anything designed or sold for incorporation

  1974 into a dwelling.  In determining whether a product is a consumer product,

  1975 doubtful cases shall be resolved in favor of coverage.  For a particular

  1976 product received by a particular user, "normally used" refers to a

  1977 typical or common use of that class of product, regardless of the status

  1978 of the particular user or of the way in which the particular user

  1979 actually uses, or expects or is expected to use, the product.  A product

  1980 is a consumer product regardless of whether the product has substantial

  1981 commercial, industrial or non-consumer uses, unless such uses represent

  1982 the only significant mode of use of the product.

  1983 

  1984   "Installation Information" for a User Product means any methods,

  1985 procedures, authorization keys, or other information required to install

  1986 and execute modified versions of a covered work in that User Product from

  1987 a modified version of its Corresponding Source.  The information must

  1988 suffice to ensure that the continued functioning of the modified object

  1989 code is in no case prevented or interfered with solely because

  1990 modification has been made.

  1991 

  1992   If you convey an object code work under this section in, or with, or

  1993 specifically for use in, a User Product, and the conveying occurs as

  1994 part of a transaction in which the right of possession and use of the

  1995 User Product is transferred to the recipient in perpetuity or for a

  1996 fixed term (regardless of how the transaction is characterized), the

  1997 Corresponding Source conveyed under this section must be accompanied

  1998 by the Installation Information.  But this requirement does not apply

  1999 if neither you nor any third party retains the ability to install

  2000 modified object code on the User Product (for example, the work has

  2001 been installed in ROM).

  2002 

  2003   The requirement to provide Installation Information does not include a

  2004 requirement to continue to provide support service, warranty, or updates

  2005 for a work that has been modified or installed by the recipient, or for

  2006 the User Product in which it has been modified or installed.  Access to a

  2007 network may be denied when the modification itself materially and

  2008 adversely affects the operation of the network or violates the rules and

  2009 protocols for communication across the network.

  2010 

  2011   Corresponding Source conveyed, and Installation Information provided,

  2012 in accord with this section must be in a format that is publicly

  2013 documented (and with an implementation available to the public in

  2014 source code form), and must require no special password or key for

  2015 unpacking, reading or copying.

  2016 

  2017   7. Additional Terms.

  2018 

  2019   "Additional permissions" are terms that supplement the terms of this

  2020 License by making exceptions from one or more of its conditions.

  2021 Additional permissions that are applicable to the entire Program shall

  2022 be treated as though they were included in this License, to the extent

  2023 that they are valid under applicable law.  If additional permissions

  2024 apply only to part of the Program, that part may be used separately

  2025 under those permissions, but the entire Program remains governed by

  2026 this License without regard to the additional permissions.

  2027 

  2028   When you convey a copy of a covered work, you may at your option

  2029 remove any additional permissions from that copy, or from any part of

  2030 it.  (Additional permissions may be written to require their own

  2031 removal in certain cases when you modify the work.)  You may place

  2032 additional permissions on material, added by you to a covered work,

  2033 for which you have or can give appropriate copyright permission.

  2034 

  2035   Notwithstanding any other provision of this License, for material you

  2036 add to a covered work, you may (if authorized by the copyright holders of

  2037 that material) supplement the terms of this License with terms:

  2038 

  2039     a) Disclaiming warranty or limiting liability differently from the

  2040     terms of sections 15 and 16 of this License; or

  2041 

  2042     b) Requiring preservation of specified reasonable legal notices or

  2043     author attributions in that material or in the Appropriate Legal

  2044     Notices displayed by works containing it; or

  2045 

  2046     c) Prohibiting misrepresentation of the origin of that material, or

  2047     requiring that modified versions of such material be marked in

  2048     reasonable ways as different from the original version; or

  2049 

  2050     d) Limiting the use for publicity purposes of names of licensors or

  2051     authors of the material; or

  2052 

  2053     e) Declining to grant rights under trademark law for use of some

  2054     trade names, trademarks, or service marks; or

  2055 

  2056     f) Requiring indemnification of licensors and authors of that

  2057     material by anyone who conveys the material (or modified versions of

  2058     it) with contractual assumptions of liability to the recipient, for

  2059     any liability that these contractual assumptions directly impose on

  2060     those licensors and authors.

  2061 

  2062   All other non-permissive additional terms are considered "further

  2063 restrictions" within the meaning of section 10.  If the Program as you

  2064 received it, or any part of it, contains a notice stating that it is

  2065 governed by this License along with a term that is a further

  2066 restriction, you may remove that term.  If a license document contains

  2067 a further restriction but permits relicensing or conveying under this

  2068 License, you may add to a covered work material governed by the terms

  2069 of that license document, provided that the further restriction does

  2070 not survive such relicensing or conveying.

  2071 

  2072   If you add terms to a covered work in accord with this section, you

  2073 must place, in the relevant source files, a statement of the

  2074 additional terms that apply to those files, or a notice indicating

  2075 where to find the applicable terms.

  2076 

  2077   Additional terms, permissive or non-permissive, may be stated in the

  2078 form of a separately written license, or stated as exceptions;

  2079 the above requirements apply either way.

  2080 

  2081   8. Termination.

  2082 

  2083   You may not propagate or modify a covered work except as expressly

  2084 provided under this License.  Any attempt otherwise to propagate or

  2085 modify it is void, and will automatically terminate your rights under

  2086 this License (including any patent licenses granted under the third

  2087 paragraph of section 11).

  2088 

  2089   However, if you cease all violation of this License, then your

  2090 license from a particular copyright holder is reinstated (a)

  2091 provisionally, unless and until the copyright holder explicitly and

  2092 finally terminates your license, and (b) permanently, if the copyright

  2093 holder fails to notify you of the violation by some reasonable means

  2094 prior to 60 days after the cessation.

  2095 

  2096   Moreover, your license from a particular copyright holder is

  2097 reinstated permanently if the copyright holder notifies you of the

  2098 violation by some reasonable means, this is the first time you have

  2099 received notice of violation of this License (for any work) from that

  2100 copyright holder, and you cure the violation prior to 30 days after

  2101 your receipt of the notice.

  2102 

  2103   Termination of your rights under this section does not terminate the

  2104 licenses of parties who have received copies or rights from you under

  2105 this License.  If your rights have been terminated and not permanently

  2106 reinstated, you do not qualify to receive new licenses for the same

  2107 material under section 10.

  2108 

  2109   9. Acceptance Not Required for Having Copies.

  2110 

  2111   You are not required to accept this License in order to receive or

  2112 run a copy of the Program.  Ancillary propagation of a covered work

  2113 occurring solely as a consequence of using peer-to-peer transmission

  2114 to receive a copy likewise does not require acceptance.  However,

  2115 nothing other than this License grants you permission to propagate or

  2116 modify any covered work.  These actions infringe copyright if you do

  2117 not accept this License.  Therefore, by modifying or propagating a

  2118 covered work, you indicate your acceptance of this License to do so.

  2119 

  2120   10. Automatic Licensing of Downstream Recipients.

  2121 

  2122   Each time you convey a covered work, the recipient automatically

  2123 receives a license from the original licensors, to run, modify and

  2124 propagate that work, subject to this License.  You are not responsible

  2125 for enforcing compliance by third parties with this License.

  2126 

  2127   An "entity transaction" is a transaction transferring control of an

  2128 organization, or substantially all assets of one, or subdividing an

  2129 organization, or merging organizations.  If propagation of a covered

  2130 work results from an entity transaction, each party to that

  2131 transaction who receives a copy of the work also receives whatever

  2132 licenses to the work the party's predecessor in interest had or could

  2133 give under the previous paragraph, plus a right to possession of the

  2134 Corresponding Source of the work from the predecessor in interest, if

  2135 the predecessor has it or can get it with reasonable efforts.

  2136 

  2137   You may not impose any further restrictions on the exercise of the

  2138 rights granted or affirmed under this License.  For example, you may

  2139 not impose a license fee, royalty, or other charge for exercise of

  2140 rights granted under this License, and you may not initiate litigation

  2141 (including a cross-claim or counterclaim in a lawsuit) alleging that

  2142 any patent claim is infringed by making, using, selling, offering for

  2143 sale, or importing the Program or any portion of it.

  2144 

  2145   11. Patents.

  2146 

  2147   A "contributor" is a copyright holder who authorizes use under this

  2148 License of the Program or a work on which the Program is based.  The

  2149 work thus licensed is called the contributor's "contributor version".

  2150 

  2151   A contributor's "essential patent claims" are all patent claims

  2152 owned or controlled by the contributor, whether already acquired or

  2153 hereafter acquired, that would be infringed by some manner, permitted

  2154 by this License, of making, using, or selling its contributor version,

  2155 but do not include claims that would be infringed only as a

  2156 consequence of further modification of the contributor version.  For

  2157 purposes of this definition, "control" includes the right to grant

  2158 patent sublicenses in a manner consistent with the requirements of

  2159 this License.

  2160 

  2161   Each contributor grants you a non-exclusive, worldwide, royalty-free

  2162 patent license under the contributor's essential patent claims, to

  2163 make, use, sell, offer for sale, import and otherwise run, modify and

  2164 propagate the contents of its contributor version.

  2165 

  2166   In the following three paragraphs, a "patent license" is any express

  2167 agreement or commitment, however denominated, not to enforce a patent

  2168 (such as an express permission to practice a patent or covenant not to

  2169 sue for patent infringement).  To "grant" such a patent license to a

  2170 party means to make such an agreement or commitment not to enforce a

  2171 patent against the party.

  2172 

  2173   If you convey a covered work, knowingly relying on a patent license,

  2174 and the Corresponding Source of the work is not available for anyone

  2175 to copy, free of charge and under the terms of this License, through a

  2176 publicly available network server or other readily accessible means,

  2177 then you must either (1) cause the Corresponding Source to be so

  2178 available, or (2) arrange to deprive yourself of the benefit of the

  2179 patent license for this particular work, or (3) arrange, in a manner

  2180 consistent with the requirements of this License, to extend the patent

  2181 license to downstream recipients.  "Knowingly relying" means you have

  2182 actual knowledge that, but for the patent license, your conveying the

  2183 covered work in a country, or your recipient's use of the covered work

  2184 in a country, would infringe one or more identifiable patents in that

  2185 country that you have reason to believe are valid.

  2186 

  2187   If, pursuant to or in connection with a single transaction or

  2188 arrangement, you convey, or propagate by procuring conveyance of, a

  2189 covered work, and grant a patent license to some of the parties

  2190 receiving the covered work authorizing them to use, propagate, modify

  2191 or convey a specific copy of the covered work, then the patent license

  2192 you grant is automatically extended to all recipients of the covered

  2193 work and works based on it.

  2194 

  2195   A patent license is "discriminatory" if it does not include within

  2196 the scope of its coverage, prohibits the exercise of, or is

  2197 conditioned on the non-exercise of one or more of the rights that are

  2198 specifically granted under this License.  You may not convey a covered

  2199 work if you are a party to an arrangement with a third party that is

  2200 in the business of distributing software, under which you make payment

  2201 to the third party based on the extent of your activity of conveying

  2202 the work, and under which the third party grants, to any of the

  2203 parties who would receive the covered work from you, a discriminatory

  2204 patent license (a) in connection with copies of the covered work

  2205 conveyed by you (or copies made from those copies), or (b) primarily

  2206 for and in connection with specific products or compilations that

  2207 contain the covered work, unless you entered into that arrangement,

  2208 or that patent license was granted, prior to 28 March 2007.

  2209 

  2210   Nothing in this License shall be construed as excluding or limiting

  2211 any implied license or other defenses to infringement that may

  2212 otherwise be available to you under applicable patent law.

  2213 

  2214   12. No Surrender of Others' Freedom.

  2215 

  2216   If conditions are imposed on you (whether by court order, agreement or

  2217 otherwise) that contradict the conditions of this License, they do not

  2218 excuse you from the conditions of this License.  If you cannot convey a

  2219 covered work so as to satisfy simultaneously your obligations under this

  2220 License and any other pertinent obligations, then as a consequence you may

  2221 not convey it at all.  For example, if you agree to terms that obligate you

  2222 to collect a royalty for further conveying from those to whom you convey

  2223 the Program, the only way you could satisfy both those terms and this

  2224 License would be to refrain entirely from conveying the Program.

  2225 

  2226   13. Use with the GNU Affero General Public License.

  2227 

  2228   Notwithstanding any other provision of this License, you have

  2229 permission to link or combine any covered work with a work licensed

  2230 under version 3 of the GNU Affero General Public License into a single

  2231 combined work, and to convey the resulting work.  The terms of this

  2232 License will continue to apply to the part which is the covered work,

  2233 but the special requirements of the GNU Affero General Public License,

  2234 section 13, concerning interaction through a network will apply to the

  2235 combination as such.

  2236 

  2237   14. Revised Versions of this License.

  2238 

  2239   The Free Software Foundation may publish revised and/or new versions of

  2240 the GNU General Public License from time to time.  Such new versions will

  2241 be similar in spirit to the present version, but may differ in detail to

  2242 address new problems or concerns.

  2243 

  2244   Each version is given a distinguishing version number.  If the

  2245 Program specifies that a certain numbered version of the GNU General

  2246 Public License "or any later version" applies to it, you have the

  2247 option of following the terms and conditions either of that numbered

  2248 version or of any later version published by the Free Software

  2249 Foundation.  If the Program does not specify a version number of the

  2250 GNU General Public License, you may choose any version ever published

  2251 by the Free Software Foundation.

  2252 

  2253   If the Program specifies that a proxy can decide which future

  2254 versions of the GNU General Public License can be used, that proxy's

  2255 public statement of acceptance of a version permanently authorizes you

  2256 to choose that version for the Program.

  2257 

  2258   Later license versions may give you additional or different

  2259 permissions.  However, no additional obligations are imposed on any

  2260 author or copyright holder as a result of your choosing to follow a

  2261 later version.

  2262 

  2263   15. Disclaimer of Warranty.

  2264 

  2265   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY

  2266 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT

  2267 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY

  2268 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,

  2269 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR

  2270 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM

  2271 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF

  2272 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

  2273 

  2274   16. Limitation of Liability.

  2275 

  2276   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

  2277 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS

  2278 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY

  2279 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE

  2280 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF

  2281 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD

  2282 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),

  2283 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF

  2284 SUCH DAMAGES.

  2285 

  2286   17. Interpretation of Sections 15 and 16.

  2287 

  2288   If the disclaimer of warranty and limitation of liability provided

  2289 above cannot be given local legal effect according to their terms,

  2290 reviewing courts shall apply local law that most closely approximates

  2291 an absolute waiver of all civil liability in connection with the

  2292 Program, unless a warranty or assumption of liability accompanies a

  2293 copy of the Program in return for a fee.

  2294 

  2295                      END OF TERMS AND CONDITIONS

  2296 

  2297             How to Apply These Terms to Your New Programs

  2298 

  2299   If you develop a new program, and you want it to be of the greatest

  2300 possible use to the public, the best way to achieve this is to make it

  2301 free software which everyone can redistribute and change under these terms.

  2302 

  2303   To do so, attach the following notices to the program.  It is safest

  2304 to attach them to the start of each source file to most effectively

  2305 state the exclusion of warranty; and each file should have at least

  2306 the "copyright" line and a pointer to where the full notice is found.

  2307 

  2308     <one line to give the program's name and a brief idea of what it does.>

  2309     Copyright (C) <year>  <name of author>

  2310 

  2311     This program is free software: you can redistribute it and/or modify

  2312     it under the terms of the GNU General Public License as published by

  2313     the Free Software Foundation, either version 3 of the License, or

  2314     (at your option) any later version.

  2315 

  2316     This program is distributed in the hope that it will be useful,

  2317     but WITHOUT ANY WARRANTY; without even the implied warranty of

  2318     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

  2319     GNU General Public License for more details.

  2320 

  2321     You should have received a copy of the GNU General Public License

  2322     along with this program.  If not, see <http://www.gnu.org/licenses/>.

  2323 

  2324 Also add information on how to contact you by electronic and paper mail.

  2325 

  2326   If the program does terminal interaction, make it output a short

  2327 notice like this when it starts in an interactive mode:

  2328 

  2329     <program>  Copyright (C) <year>  <name of author>

  2330     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

  2331     This is free software, and you are welcome to redistribute it

  2332     under certain conditions; type `show c' for details.

  2333 

  2334 The hypothetical commands `show w' and `show c' should show the appropriate

  2335 parts of the General Public License.  Of course, your program's commands

  2336 might be different; for a GUI interface, you would use an "about box".

  2337 

  2338   You should also get your employer (if you work as a programmer) or school,

  2339 if any, to sign a "copyright disclaimer" for the program, if necessary.

  2340 For more information on this, and how to apply and follow the GNU GPL, see

  2341 <http://www.gnu.org/licenses/>.

  2342 

  2343   The GNU General Public License does not permit incorporating your program

  2344 into proprietary programs.  If your program is a subroutine library, you

  2345 may consider it more useful to permit linking proprietary applications with

  2346 the library.  If this is what you want to do, use the GNU Lesser General

  2347 Public License instead of this License.  But first, please read

  2348 <http://www.gnu.org/philosophy/why-not-lgpl.html>.

  2349 

  2350 Bison Exception contained in parse.c/parse.h/ripper.c:

  2351 

  2352 /* As a special exception, you may create a larger work that contains

  2353   part or all of the Bison parser skeleton and distribute that work

  2354   under terms of your choice, so long as that work isn't itself a

  2355   parser generator using the skeleton or a modified version thereof

  2356   as a parser skeleton.  Alternatively, if you modify or redistribute

  2357   the parser skeleton itself, you may (at your option) remove this

  2358   special exception, which will cause the skeleton and the resulting

  2359   Bison output files to be licensed under the GNU General Public

  2360   License without this special exception.
