   5  Copyright (C) 1988 Richard M. Stallman
   6  Everyone is permitted to copy and distribute verbatim copies
   7  of this license, but changing it is not allowed.  You can also
   8  use this wording to make the terms for other programs.
   9
  10   The license agreements of most software companies keep you at the
  11 mercy of those companies.  By contrast, our general public license is
  12 intended to give everyone the right to share GDB.  To make sure that
  13 you get the rights we want you to have, we need to make restrictions
  14 that forbid anyone to deny you these rights or to ask you to surrender
  15 the rights.  Hence this license agreement.
  16
  17   Specifically, we want to make sure that you have the right to give
  18 away copies of GDB, that you receive source code or else can get it
  19 if you want it, that you can change GDB or use pieces of it in new
  20 free programs, and that you know you can do these things.
  21
  22   To make sure that everyone has such rights, we have to forbid you to
  23 deprive anyone else of these rights.  For example, if you distribute
  24 copies of GDB, you must give the recipients all the rights that you
  25 have.  You must make sure that they, too, receive or can get the
  26 source code.  And you must tell them their rights.
  27
  28   Also, for our own protection, we must make certain that everyone
  29 finds out that there is no warranty for GDB.  If GDB is modified by
  30 someone else and passed on, we want its recipients to know that what
  31 they have is not what we distributed, so that any problems introduced
  32 by others will not reflect on our reputation.
  33
  34   Therefore we (Richard Stallman and the Free Software Foundation,
  35 Inc.) make the following terms which say what you must do to be
  36 allowed to distribute or change GDB.

  39                         COPYING POLICIES
  40
  41   1. You may copy and distribute verbatim copies of GDB source code as
  42 you receive it, in any medium, provided that you conspicuously and
  43 appropriately publish on each copy a valid copyright notice "Copyright
  44 (C) 1988 Free Software Foundation, Inc." (or with whatever year is
  45 appropriate); keep intact the notices on all files that refer to this
  46 License Agreement and to the absence of any warranty; and give any
  47 other recipients of the GDB program a copy of this License Agreement
  48 along with the program.  You may charge a distribution fee for the
  49 physical act of transferring a copy.
  50
  51   2. You may modify your copy or copies of GDB or any portion of it,
  52 and copy and distribute such modifications under the terms of
  53 Paragraph 1 above, provided that you also do the following:
  54
  55     a) cause the modified files to carry prominent notices stating
  56     that you changed the files and the date of any change; and
  57
  58     b) cause the whole of any work that you distribute or publish,
  59     that in whole or in part contains or is a derivative of GDB or any
  60     part thereof, to be licensed at no charge to all third parties on
  61     terms identical to those contained in this License Agreement
  62     (except that you may choose to grant more extensive warranty
  63     protection to third parties, at your option).
  64
  65     c) if the modified program serves as a debugger, cause it when
  66     started running in the simplest and usual way, to print an
  67     announcement including a valid copyright notice "Copyright (C)
  68     1988 Free Software Foundation, Inc." (or with the year that is
  69     appropriate), saying that there is no warranty (or else, saying
  70     that you provide a warranty) and that users may redistribute the
  71     program under these conditions, and telling the user how to view a
  72     copy of this License Agreement.
  73
  74     d) You may charge a distribution fee for the physical act of
  75     transferring a copy, and you may at your option offer warranty
  76     protection in exchange for a fee.
  77
  78 Mere aggregation of another unrelated program with this program (or its
  79 derivative) on a volume of a storage or distribution medium does not bring
  80 the other program under the scope of these terms.
  81
  82   3. You may copy and distribute GDB (or a portion or derivative of it,
  83 under Paragraph 2) in object code or executable form under the terms of
  84 Paragraphs 1 and 2 above provided that you also do one of the following:
  85
  86     a) accompany it with the complete corresponding machine-readable
  87     source code, which must be distributed under the terms of
  88     Paragraphs 1 and 2 above; or,
  89
  90     b) accompany it with a written offer, valid for at least three
  91     years, to give any third party free (except for a nominal
  92     shipping charge) a complete machine-readable copy of the
  93     corresponding source code, to be distributed under the terms of
  94     Paragraphs 1 and 2 above; or,
  95
  96     c) accompany it with the information you received as to where the
  97     corresponding source code may be obtained.  (This alternative is
  98     allowed only for noncommercial distribution and only if you
  99     received the program in object code or executable form alone.)
 100
 101 For an executable file, complete source code means all the source code for
 102 all modules it contains; but, as a special exception, it need not include
 103 source code for modules which are standard libraries that accompany the
 104 operating system on which the executable file runs.
 105
 106   4. You may not copy, sublicense, distribute or transfer GDB
 107 except as expressly provided under this License Agreement.  Any attempt
 108 otherwise to copy, sublicense, distribute or transfer GDB is void and
 109 your rights to use the program under this License agreement shall be
 110 automatically terminated.  However, parties who have received computer
 111 software programs from you with this License Agreement will not have
 112 their licenses terminated so long as such parties remain in full compliance.
 113
 114   5. If you wish to incorporate parts of GDB into other free programs
 115 whose distribution conditions are different, write to the Free
 116 Software Foundation at 675 Mass Ave, Cambridge, MA 02139.  We have not
 117 yet worked out a simple rule that can be stated here, but we will
 118 often permit this.  We will be guided by the two goals of preserving
 119 the free status of all derivatives of our free software and of
 120 promoting the sharing and reuse of software.
 121
 122 In other words, go ahead and share GDB, but don't try to stop
 123 anyone else from sharing it farther.  Help stamp out software hoarding!
 124
 125                        NO WARRANTY
 126
 127   BECAUSE GDB IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY NO
 128 WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW.  EXCEPT
 129 WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC,
 130 RICHARD M. STALLMAN AND/OR OTHER PARTIES PROVIDE GDB "AS IS" WITHOUT
 131 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
 132 LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
 133 A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND
 134 PERFORMANCE OF GDB IS WITH YOU.  SHOULD GDB PROVE DEFECTIVE, YOU
 135 ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 136
 137  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL RICHARD M.
 138 STALLMAN, THE FREE SOFTWARE FOUNDATION, INC., AND/OR ANY OTHER PARTY
 139 WHO MAY MODIFY AND REDISTRIBUTE GDB AS PERMITTED ABOVE, BE LIABLE TO
 140 YOU FOR DAMAGES, INCLUDING ANY LOST PROFITS, LOST MONIES, OR OTHER
 141 SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
 142 INABILITY TO USE (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
 143 BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY THIRD PARTIES OR A
 144 FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS) GDB, EVEN
 145 IF YOU HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR
 146 ANY CLAIM BY ANY OTHER PARTY.
