Stallman 36 Everyone is permitted to copy and distribute verbatim copies of this 37 license, but changing it is not allowed. You can also use this wording 38 to make the terms for other programs. 39 40 The license agreements of most software companies keep you at the 41 mercy of those companies. By contrast, our general public license is 42 intended to give everyone the right to share Ghostscript. To make sure 43 that you get the rights we want you to have, we need to make 44 restrictions that forbid anyone to deny you these rights or to ask you 45 to surrender the rights. Hence this license agreement. 46 47 Specifically, we want to make sure that you have the right to give 48 away copies of Ghostscript, that you receive source code or else can get 49 it if you want it, that you can change Ghostscript or use pieces of it 50 in new free programs, and that you know you can do these things. 51 52 To make sure that everyone has such rights, we have to forbid you to 53 deprive anyone else of these rights. For example, if you distribute 54 copies of Ghostscript, you must give the recipients all the rights that 55 you have. You must make sure that they, too, receive or can get the 56 source code. And you must tell them their rights. 57 58 Also, for our own protection, we must make certain that everyone finds 59 out that there is no warranty for Ghostscript. If Ghostscript is 60 modified by someone else and passed on, we want its recipients to know 61 that what they have is not what we distributed, so that any problems 62 introduced by others will not reflect on our reputation. 63 64 Therefore we (Richard M. Stallman and the Free Software Foundation, 65 Inc.) make the following terms which say what you must do to be allowed 66 to distribute or change Ghostscript. 67 68 69 COPYING POLICIES 70 71 1. You may copy and distribute verbatim copies of Ghostscript source 72 code as you receive it, in any medium, provided that you conspicuously 73 and appropriately publish on each copy a valid copyright and license 74 notice "Copyright (C) 1989 Aladdin Enterprises. All rights reserved. 75 Distributed by Free Software Foundation, Inc." (or with whatever year is 76 appropriate); keep intact the notices on all files that refer to this 77 License Agreement and to the absence of any warranty; and give any other 78 recipients of the Ghostscript program a copy of this License Agreement 79 along with the program. You may charge a distribution fee for the 80 physical act of transferring a copy. 81 82 2. You may modify your copy or copies of Ghostscript or any portion of 83 it, and copy and distribute such modifications under the terms of 84 Paragraph 1 above, provided that you also do the following: 85 86 a) cause the modified files to carry prominent notices stating 87 that you changed the files and the date of any change; and 88 89 b) cause the whole of any work that you distribute or publish, 90 that in whole or in part contains or is a derivative of Ghostscript 91 or any part thereof, to be licensed at no charge to all third 92 parties on terms identical to those contained in this License 93 Agreement (except that you may choose to grant more extensive 94 warranty protection to some or all third parties, at your option). 95 96 c) You may charge a distribution fee for the physical act of 97 transferring a copy, and you may at your option offer warranty 98 protection in exchange for a fee. 99 100 Mere aggregation of another unrelated program with this program (or its 101 derivative) on a volume of a storage or distribution medium does not bring 102 the other program under the scope of these terms. 103 104 3. You may copy and distribute Ghostscript (or a portion or derivative 105 of it, under Paragraph 2) in object code or executable form under the 106 terms of Paragraphs 1 and 2 above provided that you also do one of the 107 following: 108 109 a) accompany it with the complete corresponding machine-readable 110 source code, which must be distributed under the terms of 111 Paragraphs 1 and 2 above; or, 112 113 b) accompany it with a written offer, valid for at least three 114 years, to give any third party free (except for a nominal 115 shipping charge) a complete machine-readable copy of the 116 corresponding source code, to be distributed under the terms of 117 Paragraphs 1 and 2 above; or, 118 119 c) accompany it with the information you received as to where the 120 corresponding source code may be obtained. (This alternative is 121 allowed only for noncommercial distribution and only if you 122 received the program in object code or executable form alone.) 123 124 For an executable file, complete source code means all the source code for 125 all modules it contains; but, as a special exception, it need not include 126 source code for modules which are standard libraries that accompany the 127 operating system on which the executable file runs. 128 129 4. You may not copy, sublicense, distribute or transfer Ghostscript 130 except as expressly provided under this License Agreement. Any attempt 131 otherwise to copy, sublicense, distribute or transfer Ghostscript is 132 void and your rights to use the program under this License agreement 133 shall be automatically terminated. However, parties who have received 134 computer software programs from you with this License Agreement will not 135 have their licenses terminated so long as such parties remain in full 136 compliance. 137 138 5. If you wish to incorporate parts of Ghostscript into other free 139 programs whose distribution conditions are different, write to the Free 140 Software Foundation at 675 Mass Ave, Cambridge, MA 02139. We have not 141 yet worked out a simple rule that can be stated here, but we will often 142 permit this. We will be guided by the two goals of preserving the free 143 status of all derivatives of our free software and of promoting the 144 sharing and reuse of software. 145 146 Your comments and suggestions about our licensing policies and our 147 software are welcome!

changed all #ifdefs 212 for configuration symbols to #ifs 213 lpd 95-04-05 changed copyright notice to make it clear that 214 including ansi2knr in a program does not bring the entire 215 program under the GPL 216 lpd 94-12-18 added conditionals for systems where ctype macros 217 don't handle 8-bit characters properly, suggested by 218 Francois Pinard <pinard@iro.umontreal.ca>; 219 removed --varargs switch (this is now the default) 220 lpd 94-10-10 removed CONFIG_BROKETS conditional 221 lpd 94-07-16 added some conditionals to help GNU `configure', 222 suggested by Francois Pinard <pinard@iro.umontreal.ca>;
