2979
2980                             Preamble
2981
2982   The licenses for most software are designed to take away your
2983 freedom to share and change it.  By contrast, the GNU General Public
2984 License is intended to guarantee your freedom to share and change free
2985 software--to make sure the software is free for all its users.  This
2986 General Public License applies to most of the Free Software
2987 Foundation's software and to any other program whose authors commit to
2988 using it.  (Some other Free Software Foundation software is covered by
2989 the GNU Library General Public License instead.)  You can apply it to
2990 your programs, too.
2991
2992   When we speak of free software, we are referring to freedom, not
2993 price.  Our General Public Licenses are designed to make sure that you
2994 have the freedom to distribute copies of free software (and charge for
2995 this service if you wish), that you receive source code or can get it
2996 if you want it, that you can change the software or use pieces of it
2997 in new free programs; and that you know you can do these things.
2998
2999   To protect your rights, we need to make restrictions that forbid
3000 anyone to deny you these rights or to ask you to surrender the rights.
3001 These restrictions translate to certain responsibilities for you if you
3002 distribute copies of the software, or if you modify it.
3003
3004   For example, if you distribute copies of such a program, whether
3005 gratis or for a fee, you must give the recipients all the rights that
3006 you have.  You must make sure that they, too, receive or can get the
3007 source code.  And you must show them these terms so they know their
3008 rights.
3009
3010   We protect your rights with two steps: (1) copyright the software, and
3011 (2) offer you this license which gives you legal permission to copy,
3012 distribute and/or modify the software.
3013
3014   Also, for each author's protection and ours, we want to make certain
3015 that everyone understands that there is no warranty for this free
3016 software.  If the software is modified by someone else and passed on, we
3017 want its recipients to know that what they have is not the original, so
3018 that any problems introduced by others will not reflect on the original
3019 authors' reputations.
3020
3021   Finally, any free program is threatened constantly by software
3022 patents.  We wish to avoid the danger that redistributors of a free
3023 program will individually obtain patent licenses, in effect making the
3024 program proprietary.  To prevent this, we have made it clear that any
3025 patent must be licensed for everyone's free use or not licensed at all.
3026
3027   The precise terms and conditions for copying, distribution and
3028 modification follow.
3029
3030
3031                     GNU GENERAL PUBLIC LICENSE
3032    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
3033
3034   0. This License applies to any program or other work which contains
3035 a notice placed by the copyright holder saying it may be distributed
3036 under the terms of this General Public License.  The "Program", below,
3037 refers to any such program or work, and a "work based on the Program"
3038 means either the Program or any derivative work under copyright law:
3039 that is to say, a work containing the Program or a portion of it,
3040 either verbatim or with modifications and/or translated into another
3041 language.  (Hereinafter, translation is included without limitation in
3042 the term "modification".)  Each licensee is addressed as "you".
3043
3044 Activities other than copying, distribution and modification are not
3045 covered by this License; they are outside its scope.  The act of
3046 running the Program is not restricted, and the output from the Program
3047 is covered only if its contents constitute a work based on the
3048 Program (independent of having been made by running the Program).
3049 Whether that is true depends on what the Program does.
3050
3051   1. You may copy and distribute verbatim copies of the Program's
3052 source code as you receive it, in any medium, provided that you
3053 conspicuously and appropriately publish on each copy an appropriate
3054 copyright notice and disclaimer of warranty; keep intact all the
3055 notices that refer to this License and to the absence of any warranty;
3056 and give any other recipients of the Program a copy of this License
3057 along with the Program.
3058
3059 You may charge a fee for the physical act of transferring a copy, and
3060 you may at your option offer warranty protection in exchange for a fee.
3061
3062   2. You may modify your copy or copies of the Program or any portion
3063 of it, thus forming a work based on the Program, and copy and
3064 distribute such modifications or work under the terms of Section 1
3065 above, provided that you also meet all of these conditions:
3066
3067     a) You must cause the modified files to carry prominent notices
3068     stating that you changed the files and the date of any change.
3069
3070     b) You must cause any work that you distribute or publish, that in
3071     whole or in part contains or is derived from the Program or any
3072     part thereof, to be licensed as a whole at no charge to all third
3073     parties under the terms of this License.
3074
3075     c) If the modified program normally reads commands interactively
3076     when run, you must cause it, when started running for such
3077     interactive use in the most ordinary way, to print or display an
3078     announcement including an appropriate copyright notice and a
3079     notice that there is no warranty (or else, saying that you provide
3080     a warranty) and that users may redistribute the program under
3081     these conditions, and telling the user how to view a copy of this
3082     License.  (Exception: if the Program itself is interactive but
3083     does not normally print such an announcement, your work based on
3084     the Program is not required to print an announcement.)
3085
3086
3087 These requirements apply to the modified work as a whole.  If
3088 identifiable sections of that work are not derived from the Program,
3089 and can be reasonably considered independent and separate works in
3090 themselves, then this License, and its terms, do not apply to those
3091 sections when you distribute them as separate works.  But when you
3092 distribute the same sections as part of a whole which is a work based
3093 on the Program, the distribution of the whole must be on the terms of
3094 this License, whose permissions for other licensees extend to the
3095 entire whole, and thus to each and every part regardless of who wrote it.
3096
3097 Thus, it is not the intent of this section to claim rights or contest
3098 your rights to work written entirely by you; rather, the intent is to
3099 exercise the right to control the distribution of derivative or
3100 collective works based on the Program.
3101
3102 In addition, mere aggregation of another work not based on the Program
3103 with the Program (or with a work based on the Program) on a volume of
3104 a storage or distribution medium does not bring the other work under
3105 the scope of this License.
3106
3107   3. You may copy and distribute the Program (or a work based on it,
3108 under Section 2) in object code or executable form under the terms of
3109 Sections 1 and 2 above provided that you also do one of the following:
3110
3111     a) Accompany it with the complete corresponding machine-readable
3112     source code, which must be distributed under the terms of Sections
3113     1 and 2 above on a medium customarily used for software interchange; or,
3114
3115     b) Accompany it with a written offer, valid for at least three
3116     years, to give any third party, for a charge no more than your
3117     cost of physically performing source distribution, a complete
3118     machine-readable copy of the corresponding source code, to be
3119     distributed under the terms of Sections 1 and 2 above on a medium
3120     customarily used for software interchange; or,
3121
3122     c) Accompany it with the information you received as to the offer
3123     to distribute corresponding source code.  (This alternative is
3124     allowed only for noncommercial distribution and only if you
3125     received the program in object code or executable form with such
3126     an offer, in accord with Subsection b above.)
3127
3128 The source code for a work means the preferred form of the work for
3129 making modifications to it.  For an executable work, complete source
3130 code means all the source code for all modules it contains, plus any
3131 associated interface definition files, plus the scripts used to
3132 control compilation and installation of the executable.  However, as a
3133 special exception, the source code distributed need not include
3134 anything that is normally distributed (in either source or binary
3135 form) with the major components (compiler, kernel, and so on) of the
3136 operating system on which the executable runs, unless that component
3137 itself accompanies the executable.
3138
3139 If distribution of executable or object code is made by offering
3140 access to copy from a designated place, then offering equivalent
3141 access to copy the source code from the same place counts as
3142 distribution of the source code, even though third parties are not
3143 compelled to copy the source along with the object code.
3144
3145
3146   4. You may not copy, modify, sublicense, or distribute the Program
3147 except as expressly provided under this License.  Any attempt
3148 otherwise to copy, modify, sublicense or distribute the Program is
3149 void, and will automatically terminate your rights under this License.
3150 However, parties who have received copies, or rights, from you under
3151 this License will not have their licenses terminated so long as such
3152 parties remain in full compliance.
3153
3154   5. You are not required to accept this License, since you have not
3155 signed it.  However, nothing else grants you permission to modify or
3156 distribute the Program or its derivative works.  These actions are
3157 prohibited by law if you do not accept this License.  Therefore, by
3158 modifying or distributing the Program (or any work based on the
3159 Program), you indicate your acceptance of this License to do so, and
3160 all its terms and conditions for copying, distributing or modifying
3161 the Program or works based on it.
3162
3163   6. Each time you redistribute the Program (or any work based on the
3164 Program), the recipient automatically receives a license from the
3165 original licensor to copy, distribute or modify the Program subject to
3166 these terms and conditions.  You may not impose any further
3167 restrictions on the recipients' exercise of the rights granted herein.
3168 You are not responsible for enforcing compliance by third parties to
3169 this License.
3170
3171   7. If, as a consequence of a court judgment or allegation of patent
3172 infringement or for any other reason (not limited to patent issues),
3173 conditions are imposed on you (whether by court order, agreement or
3174 otherwise) that contradict the conditions of this License, they do not
3175 excuse you from the conditions of this License.  If you cannot
3176 distribute so as to satisfy simultaneously your obligations under this
3177 License and any other pertinent obligations, then as a consequence you
3178 may not distribute the Program at all.  For example, if a patent
3179 license would not permit royalty-free redistribution of the Program by
3180 all those who receive copies directly or indirectly through you, then
3181 the only way you could satisfy both it and this License would be to
3182 refrain entirely from distribution of the Program.
3183
3184 If any portion of this section is held invalid or unenforceable under
3185 any particular circumstance, the balance of the section is intended to
3186 apply and the section as a whole is intended to apply in other
3187 circumstances.
3188
3189 It is not the purpose of this section to induce you to infringe any
3190 patents or other property right claims or to contest validity of any
3191 such claims; this section has the sole purpose of protecting the
3192 integrity of the free software distribution system, which is
3193 implemented by public license practices.  Many people have made
3194 generous contributions to the wide range of software distributed
3195 through that system in reliance on consistent application of that
3196 system; it is up to the author/donor to decide if he or she is willing
3197 to distribute software through any other system and a licensee cannot
3198 impose that choice.
3199
3200 This section is intended to make thoroughly clear what is believed to
3201 be a consequence of the rest of this License.
3202
3203
3204   8. If the distribution and/or use of the Program is restricted in
3205 certain countries either by patents or by copyrighted interfaces, the
3206 original copyright holder who places the Program under this License
3207 may add an explicit geographical distribution limitation excluding
3208 those countries, so that distribution is permitted only in or among
3209 countries not thus excluded.  In such case, this License incorporates
3210 the limitation as if written in the body of this License.
3211
3212   9. The Free Software Foundation may publish revised and/or new versions
3213 of the General Public License from time to time.  Such new versions will
3214 be similar in spirit to the present version, but may differ in detail to
3215 address new problems or concerns.
3216
3217 Each version is given a distinguishing version number.  If the Program
3218 specifies a version number of this License which applies to it and "any
3219 later version", you have the option of following the terms and conditions
3220 either of that version or of any later version published by the Free
3221 Software Foundation.  If the Program does not specify a version number of
3222 this License, you may choose any version ever published by the Free Software
3223 Foundation.
3224
3225   10. If you wish to incorporate parts of the Program into other free
3226 programs whose distribution conditions are different, write to the author
3227 to ask for permission.  For software which is copyrighted by the Free
3228 Software Foundation, write to the Free Software Foundation; we sometimes
3229 make exceptions for this.  Our decision will be guided by the two goals
3230 of preserving the free status of all derivatives of our free software and
3231 of promoting the sharing and reuse of software generally.
3232
3233                             NO WARRANTY
3234
3235   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
3236 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
3237 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
3238 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
3239 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
3240 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
3241 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
3242 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
3243 REPAIR OR CORRECTION.
3244
3245   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
3246 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
3247 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
3248 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
3249 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
3250 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
3251 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
3252 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
3253 POSSIBILITY OF SUCH DAMAGES.
