It's good enough the way it is. 16*0Sstevel@tonic-gate 17*0Sstevel@tonic-gate=head1 DESCRIPTION 18*0Sstevel@tonic-gate 19*0Sstevel@tonic-gateThis is B<"The GNU General Public License, version 2">. It's here so 20*0Sstevel@tonic-gatethat modules, programs, etc., that want to declare this as their 21*0Sstevel@tonic-gatedistribution license, can link to it. 22*0Sstevel@tonic-gate 23*0Sstevel@tonic-gateIt is also one of the two licenses Perl allows itself to be 24*0Sstevel@tonic-gateredistributed and/or modified; for the other one, the Perl Artistic 25*0Sstevel@tonic-gateLicense, see the L<perlartistic>. 26*0Sstevel@tonic-gate 27*0Sstevel@tonic-gate=head1 GNU GENERAL PUBLIC LICENSE 28*0Sstevel@tonic-gate 29*0Sstevel@tonic-gate GNU GENERAL PUBLIC LICENSE 30*0Sstevel@tonic-gate Version 2, June 1991 31*0Sstevel@tonic-gate 32*0Sstevel@tonic-gate Copyright (C) 1989, 1991 Free Software Foundation, Inc. 33*0Sstevel@tonic-gate 59 Temple Place - Suite 330, Boston, MA 34*0Sstevel@tonic-gate 02111-1307, USA. 35*0Sstevel@tonic-gate Everyone is permitted to copy and distribute verbatim copies 36*0Sstevel@tonic-gate of this license document, but changing it is not allowed. 37*0Sstevel@tonic-gate 38*0Sstevel@tonic-gate Preamble 39*0Sstevel@tonic-gate 40*0Sstevel@tonic-gateThe licenses for most software are designed to take away your 41*0Sstevel@tonic-gatefreedom to share and change it. By contrast, the GNU General Public 42*0Sstevel@tonic-gateLicense is intended to guarantee your freedom to share and change free 43*0Sstevel@tonic-gatesoftware--to make sure the software is free for all its users. This 44*0Sstevel@tonic-gateGeneral Public License applies to most of the Free Software 45*0Sstevel@tonic-gateFoundation's software and to any other program whose authors commit to 46*0Sstevel@tonic-gateusing it. (Some other Free Software Foundation software is covered by 47*0Sstevel@tonic-gatethe GNU Library General Public License instead.) You can apply it to 48*0Sstevel@tonic-gateyour programs, too. 49*0Sstevel@tonic-gate 50*0Sstevel@tonic-gateWhen we speak of free software, we are referring to freedom, not 51*0Sstevel@tonic-gateprice. Our General Public Licenses are designed to make sure that you 52*0Sstevel@tonic-gatehave the freedom to distribute copies of free software (and charge for 53*0Sstevel@tonic-gatethis service if you wish), that you receive source code or can get it 54*0Sstevel@tonic-gateif you want it, that you can change the software or use pieces of it 55*0Sstevel@tonic-gatein new free programs; and that you know you can do these things. 56*0Sstevel@tonic-gate 57*0Sstevel@tonic-gateTo protect your rights, we need to make restrictions that forbid 58*0Sstevel@tonic-gateanyone to deny you these rights or to ask you to surrender the rights. 59*0Sstevel@tonic-gateThese restrictions translate to certain responsibilities for you if you 60*0Sstevel@tonic-gatedistribute copies of the software, or if you modify it. 61*0Sstevel@tonic-gate 62*0Sstevel@tonic-gateFor example, if you distribute copies of such a program, whether 63*0Sstevel@tonic-gategratis or for a fee, you must give the recipients all the rights that 64*0Sstevel@tonic-gateyou have. You must make sure that they, too, receive or can get the 65*0Sstevel@tonic-gatesource code. And you must show them these terms so they know their 66*0Sstevel@tonic-gaterights. 67*0Sstevel@tonic-gate 68*0Sstevel@tonic-gateWe protect your rights with two steps: (1) copyright the software, and 69*0Sstevel@tonic-gate(2) offer you this license which gives you legal permission to copy, 70*0Sstevel@tonic-gatedistribute and/or modify the software. 71*0Sstevel@tonic-gate 72*0Sstevel@tonic-gateAlso, for each author's protection and ours, we want to make certain 73*0Sstevel@tonic-gatethat everyone understands that there is no warranty for this free 74*0Sstevel@tonic-gatesoftware. If the software is modified by someone else and passed on, we 75*0Sstevel@tonic-gatewant its recipients to know that what they have is not the original, so 76*0Sstevel@tonic-gatethat any problems introduced by others will not reflect on the original 77*0Sstevel@tonic-gateauthors' reputations. 78*0Sstevel@tonic-gate 79*0Sstevel@tonic-gateFinally, any free program is threatened constantly by software 80*0Sstevel@tonic-gatepatents. We wish to avoid the danger that redistributors of a free 81*0Sstevel@tonic-gateprogram will individually obtain patent licenses, in effect making the 82*0Sstevel@tonic-gateprogram proprietary. To prevent this, we have made it clear that any 83*0Sstevel@tonic-gatepatent must be licensed for everyone's free use or not licensed at all. 84*0Sstevel@tonic-gate 85*0Sstevel@tonic-gateThe precise terms and conditions for copying, distribution and 86*0Sstevel@tonic-gatemodification follow. 87*0Sstevel@tonic-gate 88*0Sstevel@tonic-gate-- 89*0Sstevel@tonic-gate 90*0Sstevel@tonic-gate GNU GENERAL PUBLIC LICENSE 91*0Sstevel@tonic-gate TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 92*0Sstevel@tonic-gate 93*0Sstevel@tonic-gate0. This License applies to any program or other work which contains 94*0Sstevel@tonic-gatea notice placed by the copyright holder saying it may be distributed 95*0Sstevel@tonic-gateunder the terms of this General Public License. The "Program", below, 96*0Sstevel@tonic-gaterefers to any such program or work, and a "work based on the Program" 97*0Sstevel@tonic-gatemeans either the Program or any derivative work under copyright law: 98*0Sstevel@tonic-gatethat is to say, a work containing the Program or a portion of it, 99*0Sstevel@tonic-gateeither verbatim or with modifications and/or translated into another 100*0Sstevel@tonic-gatelanguage. (Hereinafter, translation is included without limitation in 101*0Sstevel@tonic-gatethe term "modification".) Each licensee is addressed as "you". 102*0Sstevel@tonic-gate 103*0Sstevel@tonic-gateActivities other than copying, distribution and modification are not 104*0Sstevel@tonic-gatecovered by this License; they are outside its scope. The act of 105*0Sstevel@tonic-gaterunning the Program is not restricted, and the output from the Program 106*0Sstevel@tonic-gateis covered only if its contents constitute a work based on the 107*0Sstevel@tonic-gateProgram (independent of having been made by running the Program). 108*0Sstevel@tonic-gateWhether that is true depends on what the Program does. 109*0Sstevel@tonic-gate 110*0Sstevel@tonic-gate1. You may copy and distribute verbatim copies of the Program's 111*0Sstevel@tonic-gatesource code as you receive it, in any medium, provided that you 112*0Sstevel@tonic-gateconspicuously and appropriately publish on each copy an appropriate 113*0Sstevel@tonic-gatecopyright notice and disclaimer of warranty; keep intact all the 114*0Sstevel@tonic-gatenotices that refer to this License and to the absence of any warranty; 115*0Sstevel@tonic-gateand give any other recipients of the Program a copy of this License 116*0Sstevel@tonic-gatealong with the Program. 117*0Sstevel@tonic-gate 118*0Sstevel@tonic-gateYou may charge a fee for the physical act of transferring a copy, and 119*0Sstevel@tonic-gateyou may at your option offer warranty protection in exchange for a fee. 120*0Sstevel@tonic-gate 121*0Sstevel@tonic-gate2. You may modify your copy or copies of the Program or any portion 122*0Sstevel@tonic-gateof it, thus forming a work based on the Program, and copy and 123*0Sstevel@tonic-gatedistribute such modifications or work under the terms of Section 1 124*0Sstevel@tonic-gateabove, provided that you also meet all of these conditions: 125*0Sstevel@tonic-gate 126*0Sstevel@tonic-gate a) You must cause the modified files to carry prominent notices 127*0Sstevel@tonic-gate stating that you changed the files and the date of any change. 128*0Sstevel@tonic-gate 129*0Sstevel@tonic-gate b) You must cause any work that you distribute or publish, that in 130*0Sstevel@tonic-gate whole or in part contains or is derived from the Program or any 131*0Sstevel@tonic-gate part thereof, to be licensed as a whole at no charge to all third 132*0Sstevel@tonic-gate parties under the terms of this License. 133*0Sstevel@tonic-gate 134*0Sstevel@tonic-gate c) If the modified program normally reads commands interactively 135*0Sstevel@tonic-gate when run, you must cause it, when started running for such 136*0Sstevel@tonic-gate interactive use in the most ordinary way, to print or display an 137*0Sstevel@tonic-gate announcement including an appropriate copyright notice and a 138*0Sstevel@tonic-gate notice that there is no warranty (or else, saying that you provide 139*0Sstevel@tonic-gate a warranty) and that users may redistribute the program under 140*0Sstevel@tonic-gate these conditions, and telling the user how to view a copy of this 141*0Sstevel@tonic-gate License. (Exception: if the Program itself is interactive but 142*0Sstevel@tonic-gate does not normally print such an announcement, your work based on 143*0Sstevel@tonic-gate the Program is not required to print an announcement.) 144*0Sstevel@tonic-gate 145*0Sstevel@tonic-gate-- 146*0Sstevel@tonic-gate 147*0Sstevel@tonic-gateThese requirements apply to the modified work as a whole. If 148*0Sstevel@tonic-gateidentifiable sections of that work are not derived from the Program, 149*0Sstevel@tonic-gateand can be reasonably considered independent and separate works in 150*0Sstevel@tonic-gatethemselves, then this License, and its terms, do not apply to those 151*0Sstevel@tonic-gatesections when you distribute them as separate works. But when you 152*0Sstevel@tonic-gatedistribute the same sections as part of a whole which is a work based 153*0Sstevel@tonic-gateon the Program, the distribution of the whole must be on the terms of 154*0Sstevel@tonic-gatethis License, whose permissions for other licensees extend to the 155*0Sstevel@tonic-gateentire whole, and thus to each and every part regardless of who wrote it. 156*0Sstevel@tonic-gate 157*0Sstevel@tonic-gateThus, it is not the intent of this section to claim rights or contest 158*0Sstevel@tonic-gateyour rights to work written entirely by you; rather, the intent is to 159*0Sstevel@tonic-gateexercise the right to control the distribution of derivative or 160*0Sstevel@tonic-gatecollective works based on the Program. 161*0Sstevel@tonic-gate 162*0Sstevel@tonic-gateIn addition, mere aggregation of another work not based on the Program 163*0Sstevel@tonic-gatewith the Program (or with a work based on the Program) on a volume of 164*0Sstevel@tonic-gatea storage or distribution medium does not bring the other work under 165*0Sstevel@tonic-gatethe scope of this License. 166*0Sstevel@tonic-gate 167*0Sstevel@tonic-gate3. You may copy and distribute the Program (or a work based on it, 168*0Sstevel@tonic-gateunder Section 2) in object code or executable form under the terms of 169*0Sstevel@tonic-gateSections 1 and 2 above provided that you also do one of the following: 170*0Sstevel@tonic-gate 171*0Sstevel@tonic-gate a) Accompany it with the complete corresponding machine-readable 172*0Sstevel@tonic-gate source code, which must be distributed under the terms of Sections 173*0Sstevel@tonic-gate 1 and 2 above on a medium customarily used for software interchange; or, 174*0Sstevel@tonic-gate 175*0Sstevel@tonic-gate b) Accompany it with a written offer, valid for at least three 176*0Sstevel@tonic-gate years, to give any third party, for a charge no more than your 177*0Sstevel@tonic-gate cost of physically performing source distribution, a complete 178*0Sstevel@tonic-gate machine-readable copy of the corresponding source code, to be 179*0Sstevel@tonic-gate distributed under the terms of Sections 1 and 2 above on a medium 180*0Sstevel@tonic-gate customarily used for software interchange; or, 181*0Sstevel@tonic-gate 182*0Sstevel@tonic-gate c) Accompany it with the information you received as to the offer 183*0Sstevel@tonic-gate to distribute corresponding source code. (This alternative is 184*0Sstevel@tonic-gate allowed only for noncommercial distribution and only if you 185*0Sstevel@tonic-gate received the program in object code or executable form with such 186*0Sstevel@tonic-gate an offer, in accord with Subsection b above.) 187*0Sstevel@tonic-gate 188*0Sstevel@tonic-gateThe source code for a work means the preferred form of the work for 189*0Sstevel@tonic-gatemaking modifications to it. For an executable work, complete source 190*0Sstevel@tonic-gatecode means all the source code for all modules it contains, plus any 191*0Sstevel@tonic-gateassociated interface definition files, plus the scripts used to 192*0Sstevel@tonic-gatecontrol compilation and installation of the executable. However, as a 193*0Sstevel@tonic-gatespecial exception, the source code distributed need not include 194*0Sstevel@tonic-gateanything that is normally distributed (in either source or binary 195*0Sstevel@tonic-gateform) with the major components (compiler, kernel, and so on) of the 196*0Sstevel@tonic-gateoperating system on which the executable runs, unless that component 197*0Sstevel@tonic-gateitself accompanies the executable. 198*0Sstevel@tonic-gate 199*0Sstevel@tonic-gateIf distribution of executable or object code is made by offering 200*0Sstevel@tonic-gateaccess to copy from a designated place, then offering equivalent 201*0Sstevel@tonic-gateaccess to copy the source code from the same place counts as 202*0Sstevel@tonic-gatedistribution of the source code, even though third parties are not 203*0Sstevel@tonic-gatecompelled to copy the source along with the object code. 204*0Sstevel@tonic-gate 205*0Sstevel@tonic-gate-- 206*0Sstevel@tonic-gate 207*0Sstevel@tonic-gate4. You may not copy, modify, sublicense, or distribute the Program 208*0Sstevel@tonic-gateexcept as expressly provided under this License. Any attempt 209*0Sstevel@tonic-gateotherwise to copy, modify, sublicense or distribute the Program is 210*0Sstevel@tonic-gatevoid, and will automatically terminate your rights under this License. 211*0Sstevel@tonic-gateHowever, parties who have received copies, or rights, from you under 212*0Sstevel@tonic-gatethis License will not have their licenses terminated so long as such 213*0Sstevel@tonic-gateparties remain in full compliance. 214*0Sstevel@tonic-gate 215*0Sstevel@tonic-gate5. You are not required to accept this License, since you have not 216*0Sstevel@tonic-gatesigned it. However, nothing else grants you permission to modify or 217*0Sstevel@tonic-gatedistribute the Program or its derivative works. These actions are 218*0Sstevel@tonic-gateprohibited by law if you do not accept this License. Therefore, by 219*0Sstevel@tonic-gatemodifying or distributing the Program (or any work based on the 220*0Sstevel@tonic-gateProgram), you indicate your acceptance of this License to do so, and 221*0Sstevel@tonic-gateall its terms and conditions for copying, distributing or modifying 222*0Sstevel@tonic-gatethe Program or works based on it. 223*0Sstevel@tonic-gate 224*0Sstevel@tonic-gate6. Each time you redistribute the Program (or any work based on the 225*0Sstevel@tonic-gateProgram), the recipient automatically receives a license from the 226*0Sstevel@tonic-gateoriginal licensor to copy, distribute or modify the Program subject to 227*0Sstevel@tonic-gatethese terms and conditions. You may not impose any further 228*0Sstevel@tonic-gaterestrictions on the recipients' exercise of the rights granted herein. 229*0Sstevel@tonic-gateYou are not responsible for enforcing compliance by third parties to 230*0Sstevel@tonic-gatethis License. 231*0Sstevel@tonic-gate 232*0Sstevel@tonic-gate7. If, as a consequence of a court judgment or allegation of patent 233*0Sstevel@tonic-gateinfringement or for any other reason (not limited to patent issues), 234*0Sstevel@tonic-gateconditions are imposed on you (whether by court order, agreement or 235*0Sstevel@tonic-gateotherwise) that contradict the conditions of this License, they do not 236*0Sstevel@tonic-gateexcuse you from the conditions of this License. If you cannot 237*0Sstevel@tonic-gatedistribute so as to satisfy simultaneously your obligations under this 238*0Sstevel@tonic-gateLicense and any other pertinent obligations, then as a consequence you 239*0Sstevel@tonic-gatemay not distribute the Program at all. For example, if a patent 240*0Sstevel@tonic-gatelicense would not permit royalty-free redistribution of the Program by 241*0Sstevel@tonic-gateall those who receive copies directly or indirectly through you, then 242*0Sstevel@tonic-gatethe only way you could satisfy both it and this License would be to 243*0Sstevel@tonic-gaterefrain entirely from distribution of the Program. 244*0Sstevel@tonic-gate 245*0Sstevel@tonic-gateIf any portion of this section is held invalid or unenforceable under 246*0Sstevel@tonic-gateany particular circumstance, the balance of the section is intended to 247*0Sstevel@tonic-gateapply and the section as a whole is intended to apply in other 248*0Sstevel@tonic-gatecircumstances. 249*0Sstevel@tonic-gate 250*0Sstevel@tonic-gateIt is not the purpose of this section to induce you to infringe any 251*0Sstevel@tonic-gatepatents or other property right claims or to contest validity of any 252*0Sstevel@tonic-gatesuch claims; this section has the sole purpose of protecting the 253*0Sstevel@tonic-gateintegrity of the free software distribution system, which is 254*0Sstevel@tonic-gateimplemented by public license practices. Many people have made 255*0Sstevel@tonic-gategenerous contributions to the wide range of software distributed 256*0Sstevel@tonic-gatethrough that system in reliance on consistent application of that 257*0Sstevel@tonic-gatesystem; it is up to the author/donor to decide if he or she is willing 258*0Sstevel@tonic-gateto distribute software through any other system and a licensee cannot 259*0Sstevel@tonic-gateimpose that choice. 260*0Sstevel@tonic-gate 261*0Sstevel@tonic-gateThis section is intended to make thoroughly clear what is believed to 262*0Sstevel@tonic-gatebe a consequence of the rest of this License. 263*0Sstevel@tonic-gate 264*0Sstevel@tonic-gate-- 265*0Sstevel@tonic-gate 266*0Sstevel@tonic-gate8. If the distribution and/or use of the Program is restricted in 267*0Sstevel@tonic-gatecertain countries either by patents or by copyrighted interfaces, the 268*0Sstevel@tonic-gateoriginal copyright holder who places the Program under this License 269*0Sstevel@tonic-gatemay add an explicit geographical distribution limitation excluding 270*0Sstevel@tonic-gatethose countries, so that distribution is permitted only in or among 271*0Sstevel@tonic-gatecountries not thus excluded. In such case, this License incorporates 272*0Sstevel@tonic-gatethe limitation as if written in the body of this License. 273*0Sstevel@tonic-gate 274*0Sstevel@tonic-gate9. The Free Software Foundation may publish revised and/or new versions 275*0Sstevel@tonic-gateof the General Public License from time to time. Such new versions will 276*0Sstevel@tonic-gatebe similar in spirit to the present version, but may differ in detail to 277*0Sstevel@tonic-gateaddress new problems or concerns. 278*0Sstevel@tonic-gate 279*0Sstevel@tonic-gateEach version is given a distinguishing version number. If the Program 280*0Sstevel@tonic-gatespecifies a version number of this License which applies to it and "any 281*0Sstevel@tonic-gatelater version", you have the option of following the terms and conditions 282*0Sstevel@tonic-gateeither of that version or of any later version published by the Free 283*0Sstevel@tonic-gateSoftware Foundation. If the Program does not specify a version number of 284*0Sstevel@tonic-gatethis License, you may choose any version ever published by the Free Software 285*0Sstevel@tonic-gateFoundation. 286*0Sstevel@tonic-gate 287*0Sstevel@tonic-gate10. If you wish to incorporate parts of the Program into other free 288*0Sstevel@tonic-gateprograms whose distribution conditions are different, write to the author 289*0Sstevel@tonic-gateto ask for permission. For software which is copyrighted by the Free 290*0Sstevel@tonic-gateSoftware Foundation, write to the Free Software Foundation; we sometimes 291*0Sstevel@tonic-gatemake exceptions for this. Our decision will be guided by the two goals 292*0Sstevel@tonic-gateof preserving the free status of all derivatives of our free software and 293*0Sstevel@tonic-gateof promoting the sharing and reuse of software generally. 294*0Sstevel@tonic-gate 295*0Sstevel@tonic-gate NO WARRANTY 296*0Sstevel@tonic-gate 297*0Sstevel@tonic-gate11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 298*0Sstevel@tonic-gateFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 299*0Sstevel@tonic-gateOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 300*0Sstevel@tonic-gatePROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 301*0Sstevel@tonic-gateOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 302*0Sstevel@tonic-gateMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 303*0Sstevel@tonic-gateTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 304*0Sstevel@tonic-gatePROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 305*0Sstevel@tonic-gateREPAIR OR CORRECTION. 306*0Sstevel@tonic-gate 307*0Sstevel@tonic-gate12.
