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 |
|

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. |
