This<a name="line15" href="#line15"> 15</a> General Public License applies to most of the Free Software<a name="line16" href="#line16"> 16</a> Foundation's software and to any other program whose authors commit to<a name="line17" href="#line17"> 17</a> using it. (Some other Free Software Foundation software is covered by<a name="line18" href="#line18"> 18</a> the GNU Library General Public License instead.) You can apply it to<a name="line19" href="#line19"> 19</a> your programs, too.<a name="line20" href="#line20"> 20</a><a name="line21" href="#line21"> 21</a> When we speak of free software, we are referring to freedom, not<a name="line22" href="#line22"> 22</a> price. Our General Public Licenses are designed to make sure that you<a name="line23" href="#line23"> 23</a> have the freedom to distribute copies of free software (and charge for<a name="line24" href="#line24"> 24</a> this service if you wish), that you receive source code or can get it<a name="line25" href="#line25"> 25</a> if you want it, that you can change the software or use pieces of it<a name="line26" href="#line26"> 26</a> in new free programs; and that you know you can do these things.<a name="line27" href="#line27"> 27</a><a name="line28" href="#line28"> 28</a> To protect your rights, we need to make restrictions that forbid<a name="line29" href="#line29"> 29</a> anyone to deny you these rights or to ask you to surrender the rights.<a name="line30" href="#line30"> 30</a> These restrictions translate to certain responsibilities for you if you<a name="line31" href="#line31"> 31</a> distribute copies of the software, or if you modify it.<a name="line32" href="#line32"> 32</a><a name="line33" href="#line33"> 33</a> For example, if you distribute copies of such a program, whether<a name="line34" href="#line34"> 34</a> gratis or for a fee, you must give the recipients all the rights that<a name="line35" href="#line35"> 35</a> you have. You must make sure that they, too, receive or can get the<a name="line36" href="#line36"> 36</a> source code.

If the software is modified by someone else and passed on, we<a name="line46" href="#line46"> 46</a> want its recipients to know that what they have is not the original, so<a name="line47" href="#line47"> 47</a> that any problems introduced by others will not reflect on the original<a name="line48" href="#line48"> 48</a> authors' reputations.<a name="line49" href="#line49"> 49</a><a name="line50" href="#line50"> 50</a> Finally, any free program is threatened constantly by software<a name="line51" href="#line51"> 51</a> patents.

To prevent this, we have made it clear that any<a name="line54" href="#line54"> 54</a> patent must be licensed for everyone's free use or not licensed at all.<a name="line55" href="#line55"> 55</a><a name="line56" href="#line56"> 56</a> The precise terms and conditions for copying, distribution and<a name="line57" href="#line57"> 57</a> modification follow.<a name="line58" href="#line58"> 58</a><a name="line59" href="#line59"> 59</a> GNU GENERAL PUBLIC LICENSE<a name="line60" href="#line60"> 60</a> TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION<a name="line61" href="#line61"> 61</a><a name="line62" href="#line62"> 62</a> 0. This License applies to any program or other work which contains<a name="line63" href="#line63"> 63</a> a notice placed by the copyright holder saying it may be distributed<a name="line64" href="#line64"> 64</a> under the terms of this General Public License. The "Program", below,<a name="line65" href="#line65"> 65</a> refers to any such program or work, and a "work based on the Program"<a name="line66" href="#line66"> 66</a> means either the Program or any derivative work under copyright law:<a name="line67" href="#line67"> 67</a> that is to say, a work containing the Program or a portion of it,<a name="line68" href="#line68"> 68</a> either verbatim or with modifications and/or translated into another<a name="line69" href="#line69"> 69</a> language. (Hereinafter, translation is included without limitation in<a name="line70" href="#line70"> 70</a> the term "modification".) Each licensee is addressed as "you".<a name="line71" href="#line71"> 71</a><a name="line72" href="#line72"> 72</a> Activities other than copying, distribution and modification are not<a name="line73" href="#line73"> 73</a> covered by this License; they are outside its scope. The act of<a name="line74" href="#line74"> 74</a> running the Program is not restricted, and the output from the Program<a name="line75" href="#line75"> 75</a> is covered only if its contents constitute a work based on the<a name="line76" href="#line76"> 76</a> Program (independent of having been made by running the Program).<a name="line77" href="#line77"> 77</a> Whether that is true depends on what the Program does.<a name="line78" href="#line78"> 78</a><a name="line79" href="#line79"> 79</a> 1. You may copy and distribute verbatim copies of the Program's<a name="line80" href="#line80"> 80</a> source code as you receive it, in any medium, provided that you<a name="line81" href="#line81"> 81</a> conspicuously and appropriately publish on each copy an appropriate<a name="line82" href="#line82"> 82</a> copyright notice and disclaimer of warranty; keep intact all the<a name="line83" href="#line83"> 83</a> notices that refer to this License and to the absence of any warranty;<a name="line84" href="#line84"> 84</a> and give any other recipients of the Program a copy of this License<a name="line85" href="#line85"> 85</a> along with the Program.<a name="line86" href="#line86"> 86</a><a name="line87" href="#line87"> 87</a> You may charge a fee for the physical act of transferring a copy, and<a name="line88" href="#line88"> 88</a> you may at your option offer warranty protection in exchange for a fee.<a name="line89" href="#line89"> 89</a><a name="line90" href="#line90"> 90</a> 2. You may modify your copy or copies of the Program or any portion<a name="line91" href="#line91"> 91</a> of it, thus forming a work based on the Program, and copy and<a name="line92" href="#line92"> 92</a> distribute such modifications or work under the terms of Section 1<a name="line93" href="#line93"> 93</a> above, provided that you also meet all of these conditions:<a name="line94" href="#line94"> 94</a><a name="line95" href="#line95"> 95</a> a) You must cause the modified files to carry prominent notices<a name="line96" href="#line96"> 96</a> stating that you changed the files and the date of any change.<a name="line97" href="#line97"> 97</a><a name="line98" href="#line98"> 98</a> b) You must cause any work that you distribute or publish, that in<a name="line99" href="#line99"> 99</a> whole or in part contains or is derived from the Program or any<a name="line100" href="#line100">100</a> part thereof, to be licensed as a whole at no charge to all third<a name="line101" href="#line101">101</a> parties under the terms of this License.<a name="line102" href="#line102">102</a><a name="line103" href="#line103">103</a> c) If the modified program normally reads commands interactively<a name="line104" href="#line104">104</a> when run, you must cause it, when started running for such<a name="line105" href="#line105">105</a> interactive use in the most ordinary way, to print or display an<a name="line106" href="#line106">106</a> announcement including an appropriate copyright notice and a<a name="line107" href="#line107">107</a> notice that there is no warranty (or else, saying that you provide<a name="line108" href="#line108">108</a> a warranty) and that users may redistribute the program under<a name="line109" href="#line109">109</a> these conditions, and telling the user how to view a copy of this<a name="line110" href="#line110">110</a> License. (Exception: if the Program itself is interactive but<a name="line111" href="#line111">111</a> does not normally print such an announcement, your work based on<a name="line112" href="#line112">112</a> the Program is not required to print an announcement.)<a name="line113" href="#line113">113</a><a name="line114" href="#line114">114</a> These requirements apply to the modified work as a whole. If<a name="line115" href="#line115">115</a> identifiable sections of that work are not derived from the Program,<a name="line116" href="#line116">116</a> and can be reasonably considered independent and separate works in<a name="line117" href="#line117">117</a> themselves, then this License, and its terms, do not apply to those<a name="line118" href="#line118">118</a> sections when you distribute them as separate works. But when you<a name="line119" href="#line119">119</a> distribute the same sections as part of a whole which is a work based<a name="line120" href="#line120">120</a> on the Program, the distribution of the whole must be on the terms of<a name="line121" href="#line121">121</a> this License, whose permissions for other licensees extend to the<a name="line122" href="#line122">122</a> entire whole, and thus to each and every part regardless of who wrote it.<a name="line123" href="#line123">123</a><a name="line124" href="#line124">124</a> Thus, it is not the intent of this section to claim rights or contest<a name="line125" href="#line125">125</a> your rights to work written entirely by you; rather, the intent is to<a name="line126" href="#line126">126</a> exercise the right to control the distribution of derivative or<a name="line127" href="#line127">127</a> collective works based on the Program.<a name="line128" href="#line128">128</a><a name="line129" href="#line129">129</a> In addition, mere aggregation of another work not based on the Program<a name="line130" href="#line130">130</a> with the Program (or with a work based on the Program) on a volume of<a name="line131" href="#line131">131</a> a storage or distribution medium does not bring the other work under<a name="line132" href="#line132">132</a> the scope of this License.<a name="line133" href="#line133">133</a><a name="line134" href="#line134">134</a> 3. You may copy and distribute the Program (or a work based on it,<a name="line135" href="#line135">135</a> under Section 2) in object code or executable form under the terms of<a name="line136" href="#line136">136</a> Sections 1 and 2 above provided that you also do one of the following:<a name="line137" href="#line137">137</a><a name="line138" href="#line138">138</a> a) Accompany it with the complete corresponding machine-readable<a name="line139" href="#line139">139</a> source code, which must be distributed under the terms of Sections<a name="line140" href="#line140">140</a> 1 and 2 above on a medium customarily used for software interchange; or,<a name="line141" href="#line141">141</a><a name="line142" href="#line142">142</a> b) Accompany it with a written offer, valid for at least three<a name="line143" href="#line143">143</a> years, to give any third party, for a charge no more than your<a name="line144" href="#line144">144</a> cost of physically performing source distribution, a complete<a name="line145" href="#line145">145</a> machine-readable copy of the corresponding source code, to be<a name="line146" href="#line146">146</a> distributed under the terms of Sections 1 and 2 above on a medium<a name="line147" href="#line147">147</a> customarily used for software interchange; or,<a name="line148" href="#line148">148</a><a name="line149" href="#line149">149</a> c) Accompany it with the information you received as to the offer<a name="line150" href="#line150">150</a> to distribute corresponding source code. (This alternative is<a name="line151" href="#line151">151</a> allowed only for noncommercial distribution and only if you<a name="line152" href="#line152">152</a> received the program in object code or executable form with such<a name="line153" href="#line153">153</a> an offer, in accord with Subsection b above.)<a name="line154" href="#line154">154</a><a name="line155" href="#line155">155</a> The source code for a work means the preferred form of the work for<a name="line156" href="#line156">156</a> making modifications to it. For an executable work, complete source<a name="line157" href="#line157">157</a> code means all the source code for all modules it contains, plus any<a name="line158" href="#line158">158</a> associated interface definition files, plus the scripts used to<a name="line159" href="#line159">159</a> control compilation and installation of the executable. However, as a<a name="line160" href="#line160">160</a> special exception, the source code distributed need not include<a name="line161" href="#line161">161</a> anything that is normally distributed (in either source or binary<a name="line162" href="#line162">162</a> form) with the major components (compiler, kernel, and so on) of the<a name="line163" href="#line163">163</a> operating system on which the executable runs, unless that component<a name="line164" href="#line164">164</a> itself accompanies the executable.<a name="line165" href="#line165">165</a><a name="line166" href="#line166">166</a> If distribution of executable or object code is made by offering<a name="line167" href="#line167">167</a> access to copy from a designated place, then offering equivalent<a name="line168" href="#line168">168</a> access to copy the source code from the same place counts as<a name="line169" href="#line169">169</a> distribution of the source code, even though third parties are not<a name="line170" href="#line170">170</a> compelled to copy the source along with the object code.<a name="line171" href="#line171">171</a><a name="line172" href="#line172">172</a> 4. You may not copy, modify, sublicense, or distribute the Program<a name="line173" href="#line173">173</a> except as expressly provided under this License. Any attempt<a name="line174" href="#line174">174</a> otherwise to copy, modify, sublicense or distribute the Program is<a name="line175" href="#line175">175</a> void, and will automatically terminate your rights under this License.<a name="line176" href="#line176">176</a> However, parties who have received copies, or rights, from you under<a name="line177" href="#line177">177</a> this License will not have their licenses terminated so long as such<a name="line178" href="#line178">178</a> parties remain in full compliance.<a name="line179" href="#line179">179</a><a name="line180" href="#line180">180</a> 5. You are not required to accept this License, since you have not<a name="line181" href="#line181">181</a> signed it. However, nothing else grants you permission to modify or<a name="line182" href="#line182">182</a> distribute the Program or its derivative works. These actions are<a name="line183" href="#line183">183</a> prohibited by law if you do not accept this License. Therefore, by<a name="line184" href="#line184">184</a> modifying or distributing the Program (or any work based on the<a name="line185" href="#line185">185</a> Program), you indicate your acceptance of this License to do so, and<a name="line186" href="#line186">186</a> all its terms and conditions for copying, distributing or modifying<a name="line187" href="#line187">187</a> the Program or works based on it.<a name="line188" href="#line188">188</a><a name="line189" href="#line189">189</a> 6. Each time you redistribute the Program (or any work based on the<a name="line190" href="#line190">190</a> Program), the recipient automatically receives a license from the<a name="line191" href="#line191">191</a> original licensor to copy, distribute or modify the Program subject to<a name="line192" href="#line192">192</a> these terms and conditions. You may not impose any further<a name="line193" href="#line193">193</a> restrictions on the recipients' exercise of the rights granted herein.<a name="line194" href="#line194">194</a> You are not responsible for enforcing compliance by third parties to<a name="line195" href="#line195">195</a> this License.<a name="line196" href="#line196">196</a><a name="line197" href="#line197">197</a> 7. If, as a consequence of a court judgment or allegation of patent<a name="line198" href="#line198">198</a> infringement or for any other reason (not limited to patent issues),<a name="line199" href="#line199">199</a> conditions are imposed on you (whether by court order, agreement or<a name="line200" href="#line200">200</a> otherwise) that contradict the conditions of this License, they do not<a name="line201" href="#line201">201</a> excuse you from the conditions of this License. If you cannot<a name="line202" href="#line202">202</a> distribute so as to satisfy simultaneously your obligations under this<a name="line203" href="#line203">203</a> License and any other pertinent obligations, then as a consequence you<a name="line204" href="#line204">204</a> may not distribute the Program at all. For example, if a patent<a name="line205" href="#line205">205</a> license would not permit royalty-free redistribution of the Program by<a name="line206" href="#line206">206</a> all those who receive copies directly or indirectly through you, then<a name="line207" href="#line207">207</a> the only way you could satisfy both it and this License would be to<a name="line208" href="#line208">208</a> refrain entirely from distribution of the Program.<a name="line209" href="#line209">209</a><a name="line210" href="#line210">210</a> If any portion of this section is held invalid or unenforceable under<a name="line211" href="#line211">211</a> any particular circumstance, the balance of the section is intended to<a name="line212" href="#line212">212</a> apply and the section as a whole is intended to apply in other<a name="line213" href="#line213">213</a> circumstances.<a name="line214" href="#line214">214</a><a name="line215" href="#line215">215</a> It is not the purpose of this section to induce you to infringe any<a name="line216" href="#line216">216</a> patents or other property right claims or to contest validity of any<a name="line217" href="#line217">217</a> such claims; this section has the sole purpose of protecting the<a name="line218" href="#line218">218</a> integrity of the free software distribution system, which is<a name="line219" href="#line219">219</a> implemented by public license practices. Many people have made<a name="line220" href="#line220">220</a> generous contributions to the wide range of software distributed<a name="line221" href="#line221">221</a> through that system in reliance on consistent application of that<a name="line222" href="#line222">222</a> system; it is up to the author/donor to decide if he or she is willing<a name="line223" href="#line223">223</a> to distribute software through any other system and a licensee cannot<a name="line224" href="#line224">224</a> impose that choice.<a name="line225" href="#line225">225</a><a name="line226" href="#line226">226</a> This section is intended to make thoroughly clear what is believed to<a name="line227" href="#line227">227</a> be a consequence of the rest of this License.<a name="line228" href="#line228">228</a><a name="line229" href="#line229">229</a> 8. If the distribution and/or use of the Program is restricted in<a name="line230" href="#line230">230</a> certain countries either by patents or by copyrighted interfaces, the<a name="line231" href="#line231">231</a> original copyright holder who places the Program under this License<a name="line232" href="#line232">232</a> may add an explicit geographical distribution limitation excluding<a name="line233" href="#line233">233</a> those countries, so that distribution is permitted only in or among<a name="line234" href="#line234">234</a> countries not thus excluded. In such case, this License incorporates<a name="line235" href="#line235">235</a> the limitation as if written in the body of this License.<a name="line236" href="#line236">236</a><a name="line237" href="#line237">237</a> 9. The Free Software Foundation may publish revised and/or new versions<a name="line238" href="#line238">238</a> of the General Public License from time to time. Such new versions will<a name="line239" href="#line239">239</a> be similar in spirit to the present version, but may differ in detail to<a name="line240" href="#line240">240</a> address new problems or concerns.<a name="line241" href="#line241">241</a><a name="line242" href="#line242">242</a> Each version is given a distinguishing version number. If the Program<a name="line243" href="#line243">243</a> specifies a version number of this License which applies to it and "any<a name="line244" href="#line244">244</a> later version", you have the option of following the terms and conditions<a name="line245" href="#line245">245</a> either of that version or of any later version published by the Free<a name="line246" href="#line246">246</a> Software Foundation. If the Program does not specify a version number of<a name="line247" href="#line247">247</a> this License, you may choose any version ever published by the Free Software<a name="line248" href="#line248">248</a> Foundation.<a name="line249" href="#line249">249</a><a name="line250" href="#line250">250</a> 10.
