2993
2994                             Preamble
2995
2996   The licenses for most software are designed to take away your
2997 freedom to share and change it.  By contrast, the GNU General Public
2998 License is intended to guarantee your freedom to share and change free
2999 software--to make sure the software is free for all its users.  This
3000 General Public License applies to most of the Free Software
3001 Foundation's software and to any other program whose authors commit to
3002 using it.  (Some other Free Software Foundation software is covered by
3003 the GNU Library General Public License instead.)  You can apply it to
3004 your programs, too.
3005
3006   When we speak of free software, we are referring to freedom, not
3007 price.  Our General Public Licenses are designed to make sure that you
3008 have the freedom to distribute copies of free software (and charge for
3009 this service if you wish), that you receive source code or can get it
3010 if you want it, that you can change the software or use pieces of it
3011 in new free programs; and that you know you can do these things.
3012
3013   To protect your rights, we need to make restrictions that forbid
3014 anyone to deny you these rights or to ask you to surrender the rights.
3015 These restrictions translate to certain responsibilities for you if you
3016 distribute copies of the software, or if you modify it.
3017
3018   For example, if you distribute copies of such a program, whether
3019 gratis or for a fee, you must give the recipients all the rights that
3020 you have.  You must make sure that they, too, receive or can get the
3021 source code.  And you must show them these terms so they know their
3022 rights.
3023
3024   We protect your rights with two steps: (1) copyright the software, and
3025 (2) offer you this license which gives you legal permission to copy,
3026 distribute and/or modify the software.
3027
3028   Also, for each author's protection and ours, we want to make certain
3029 that everyone understands that there is no warranty for this free
3030 software.  If the software is modified by someone else and passed on, we
3031 want its recipients to know that what they have is not the original, so
3032 that any problems introduced by others will not reflect on the original
3033 authors' reputations.
3034
3035   Finally, any free program is threatened constantly by software
3036 patents.  We wish to avoid the danger that redistributors of a free
3037 program will individually obtain patent licenses, in effect making the
3038 program proprietary.  To prevent this, we have made it clear that any
3039 patent must be licensed for everyone's free use or not licensed at all.
3040
3041   The precise terms and conditions for copying, distribution and
3042 modification follow.
3043
3044
3045                     GNU GENERAL PUBLIC LICENSE
3046    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
3047
3048   0. This License applies to any program or other work which contains
3049 a notice placed by the copyright holder saying it may be distributed
3050 under the terms of this General Public License.  The "Program", below,
3051 refers to any such program or work, and a "work based on the Program"
3052 means either the Program or any derivative work under copyright law:
3053 that is to say, a work containing the Program or a portion of it,
3054 either verbatim or with modifications and/or translated into another
3055 language.  (Hereinafter, translation is included without limitation in
3056 the term "modification".)  Each licensee is addressed as "you".
3057
3058 Activities other than copying, distribution and modification are not
3059 covered by this License; they are outside its scope.  The act of
3060 running the Program is not restricted, and the output from the Program
3061 is covered only if its contents constitute a work based on the
3062 Program (independent of having been made by running the Program).
3063 Whether that is true depends on what the Program does.
3064
3065   1. You may copy and distribute verbatim copies of the Program's
3066 source code as you receive it, in any medium, provided that you
3067 conspicuously and appropriately publish on each copy an appropriate
3068 copyright notice and disclaimer of warranty; keep intact all the
3069 notices that refer to this License and to the absence of any warranty;
3070 and give any other recipients of the Program a copy of this License
3071 along with the Program.
3072
3073 You may charge a fee for the physical act of transferring a copy, and
3074 you may at your option offer warranty protection in exchange for a fee.
3075
3076   2. You may modify your copy or copies of the Program or any portion
3077 of it, thus forming a work based on the Program, and copy and
3078 distribute such modifications or work under the terms of Section 1
3079 above, provided that you also meet all of these conditions:
3080
3081     a) You must cause the modified files to carry prominent notices
3082     stating that you changed the files and the date of any change.
3083
3084     b) You must cause any work that you distribute or publish, that in
3085     whole or in part contains or is derived from the Program or any
3086     part thereof, to be licensed as a whole at no charge to all third
3087     parties under the terms of this License.
3088
3089     c) If the modified program normally reads commands interactively
3090     when run, you must cause it, when started running for such
3091     interactive use in the most ordinary way, to print or display an
3092     announcement including an appropriate copyright notice and a
3093     notice that there is no warranty (or else, saying that you provide
3094     a warranty) and that users may redistribute the program under
3095     these conditions, and telling the user how to view a copy of this
3096     License.  (Exception: if the Program itself is interactive but
3097     does not normally print such an announcement, your work based on
3098     the Program is not required to print an announcement.)
3099
3100
3101 These requirements apply to the modified work as a whole.  If
3102 identifiable sections of that work are not derived from the Program,
3103 and can be reasonably considered independent and separate works in
3104 themselves, then this License, and its terms, do not apply to those
3105 sections when you distribute them as separate works.  But when you
3106 distribute the same sections as part of a whole which is a work based
3107 on the Program, the distribution of the whole must be on the terms of
3108 this License, whose permissions for other licensees extend to the
3109 entire whole, and thus to each and every part regardless of who wrote it.
3110
3111 Thus, it is not the intent of this section to claim rights or contest
3112 your rights to work written entirely by you; rather, the intent is to
3113 exercise the right to control the distribution of derivative or
3114 collective works based on the Program.
3115
3116 In addition, mere aggregation of another work not based on the Program
3117 with the Program (or with a work based on the Program) on a volume of
3118 a storage or distribution medium does not bring the other work under
3119 the scope of this License.
3120
3121   3. You may copy and distribute the Program (or a work based on it,
3122 under Section 2) in object code or executable form under the terms of
3123 Sections 1 and 2 above provided that you also do one of the following:
3124
3125     a) Accompany it with the complete corresponding machine-readable
3126     source code, which must be distributed under the terms of Sections
3127     1 and 2 above on a medium customarily used for software interchange; or,
3128
3129     b) Accompany it with a written offer, valid for at least three
3130     years, to give any third party, for a charge no more than your
3131     cost of physically performing source distribution, a complete
3132     machine-readable copy of the corresponding source code, to be
3133     distributed under the terms of Sections 1 and 2 above on a medium
3134     customarily used for software interchange; or,
3135
3136     c) Accompany it with the information you received as to the offer
3137     to distribute corresponding source code.  (This alternative is
3138     allowed only for noncommercial distribution and only if you
3139     received the program in object code or executable form with such
3140     an offer, in accord with Subsection b above.)
3141
3142 The source code for a work means the preferred form of the work for
3143 making modifications to it.  For an executable work, complete source
3144 code means all the source code for all modules it contains, plus any
3145 associated interface definition files, plus the scripts used to
3146 control compilation and installation of the executable.  However, as a
3147 special exception, the source code distributed need not include
3148 anything that is normally distributed (in either source or binary
3149 form) with the major components (compiler, kernel, and so on) of the
3150 operating system on which the executable runs, unless that component
3151 itself accompanies the executable.
3152
3153 If distribution of executable or object code is made by offering
3154 access to copy from a designated place, then offering equivalent
3155 access to copy the source code from the same place counts as
3156 distribution of the source code, even though third parties are not
3157 compelled to copy the source along with the object code.
3158
3159
3160   4. You may not copy, modify, sublicense, or distribute the Program
3161 except as expressly provided under this License.  Any attempt
3162 otherwise to copy, modify, sublicense or distribute the Program is
3163 void, and will automatically terminate your rights under this License.
3164 However, parties who have received copies, or rights, from you under
3165 this License will not have their licenses terminated so long as such
3166 parties remain in full compliance.
3167
3168   5. You are not required to accept this License, since you have not
3169 signed it.  However, nothing else grants you permission to modify or
3170 distribute the Program or its derivative works.  These actions are
3171 prohibited by law if you do not accept this License.  Therefore, by
3172 modifying or distributing the Program (or any work based on the
3173 Program), you indicate your acceptance of this License to do so, and
3174 all its terms and conditions for copying, distributing or modifying
3175 the Program or works based on it.
3176
3177   6. Each time you redistribute the Program (or any work based on the
3178 Program), the recipient automatically receives a license from the
3179 original licensor to copy, distribute or modify the Program subject to
3180 these terms and conditions.  You may not impose any further
3181 restrictions on the recipients' exercise of the rights granted herein.
3182 You are not responsible for enforcing compliance by third parties to
3183 this License.
3184
3185   7. If, as a consequence of a court judgment or allegation of patent
3186 infringement or for any other reason (not limited to patent issues),
3187 conditions are imposed on you (whether by court order, agreement or
3188 otherwise) that contradict the conditions of this License, they do not
3189 excuse you from the conditions of this License.  If you cannot
3190 distribute so as to satisfy simultaneously your obligations under this
3191 License and any other pertinent obligations, then as a consequence you
3192 may not distribute the Program at all.  For example, if a patent
3193 license would not permit royalty-free redistribution of the Program by
3194 all those who receive copies directly or indirectly through you, then
3195 the only way you could satisfy both it and this License would be to
3196 refrain entirely from distribution of the Program.
3197
3198 If any portion of this section is held invalid or unenforceable under
3199 any particular circumstance, the balance of the section is intended to
3200 apply and the section as a whole is intended to apply in other
3201 circumstances.
3202
3203 It is not the purpose of this section to induce you to infringe any
3204 patents or other property right claims or to contest validity of any
3205 such claims; this section has the sole purpose of protecting the
3206 integrity of the free software distribution system, which is
3207 implemented by public license practices.  Many people have made
3208 generous contributions to the wide range of software distributed
3209 through that system in reliance on consistent application of that
3210 system; it is up to the author/donor to decide if he or she is willing
3211 to distribute software through any other system and a licensee cannot
3212 impose that choice.
3213
3214 This section is intended to make thoroughly clear what is believed to
3215 be a consequence of the rest of this License.
3216
3217
3218   8. If the distribution and/or use of the Program is restricted in
3219 certain countries either by patents or by copyrighted interfaces, the
3220 original copyright holder who places the Program under this License
3221 may add an explicit geographical distribution limitation excluding
3222 those countries, so that distribution is permitted only in or among
3223 countries not thus excluded.  In such case, this License incorporates
3224 the limitation as if written in the body of this License.
3225
3226   9. The Free Software Foundation may publish revised and/or new versions
3227 of the General Public License from time to time.  Such new versions will
3228 be similar in spirit to the present version, but may differ in detail to
3229 address new problems or concerns.
3230
3231 Each version is given a distinguishing version number.  If the Program
3232 specifies a version number of this License which applies to it and "any
3233 later version", you have the option of following the terms and conditions
3234 either of that version or of any later version published by the Free
3235 Software Foundation.  If the Program does not specify a version number of
3236 this License, you may choose any version ever published by the Free Software
3237 Foundation.
3238
3239   10. If you wish to incorporate parts of the Program into other free
3240 programs whose distribution conditions are different, write to the author
3241 to ask for permission.  For software which is copyrighted by the Free
3242 Software Foundation, write to the Free Software Foundation; we sometimes
3243 make exceptions for this.  Our decision will be guided by the two goals
3244 of preserving the free status of all derivatives of our free software and
3245 of promoting the sharing and reuse of software generally.
3246
3247                             NO WARRANTY
3248
3249   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
3250 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
3251 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
3252 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
3253 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
3254 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
3255 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
3256 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
3257 REPAIR OR CORRECTION.
3258
3259   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
3260 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
3261 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
3262 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
3263 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
3264 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
3265 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
3266 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
3267 POSSIBILITY OF SUCH DAMAGES.
