   4
   5  Copyright (C) 1986 Richard M. Stallman
   6  Everyone is permitted to copy and distribute verbatim copies
   7  of this license, but changing it is not allowed.
   8
   9   The license agreements of most software companies keep you at the
  10 mercy of those companies.  By contrast, our general public license is
  11 intended to give everyone the right to share GDB.  To make sure that
  12 you get the rights we want you to have, we need to make restrictions
  13 that forbid anyone to deny you these rights or to ask you to surrender
  14 the rights.  Hence this license agreement.
  15
  16   Specifically, we want to make sure that you have the right to give
  17 away copies of GDB, that you receive source code or else can get it
  18 if you want it, that you can change GDB or use pieces of it in new
  19 free programs, and that you know you can do these things.
  20
  21   To make sure that everyone has such rights, we have to forbid you to
  22 deprive anyone else of these rights.  For example, if you distribute
  23 copies of GDB, you must give the recipients all the rights that you
  24 have.  You must make sure that they, too, receive or can get the
  25 source code.  And you must tell them their rights.
  26
  27   Also, for our own protection, we must make certain that everyone
  28 finds out that there is no warranty for GDB.  If GDB is modified by
  29 someone else and passed on, we want its recipients to know that what
  30 they have is not what we distributed, so that any problems introduced
  31 by others will not reflect on our reputation.
  32
  33   Therefore we (Richard Stallman and the Free Software Foundation,
  34 Inc.) make the following terms which say what you must do to be
  35 allowed to distribute or change GDB.

  37
  38                         COPYING POLICIES
  39
  40   1. You may copy and distribute verbatim copies of GDB source code as
  41 you receive it, in any medium, provided that you conspicuously and
  42 appropriately publish on each copy a valid copyright notice "Copyright
  43 (C) 1986 Free Software Foundation, Inc." (or with the year updated if
  44 that is appropriate); keep intact the notices on all files that refer
  45 to this License Agreement and to the absence of any warranty; and give
  46 any other recipients of the GDB program a copy of this License
  47 Agreement along with the program.  You may charge a distribution fee
  48 for the physical act of transferring a copy.
  49
  50   2. You may modify your copy or copies of GDB or any portion of it,
  51 and copy and distribute such modifications under the terms of
  52 Paragraph 1 above, provided that you also do the following:
  53
  54     a) cause the modified files to carry prominent notices stating
  55     that you changed the files and the date of any change; and
  56
  57     b) cause the whole of any work that you distribute or publish,
  58     that in whole or in part contains or is a derivative of GDB or any
  59     part thereof, to be licensed at no charge to all third parties on
  60     terms identical to those contained in this License Agreement
  61     (except that you may choose to grant more extensive warranty
  62     protection to third parties, at your option).
  63
  64     c) if the modified program serves as a debugger, cause it
  65     when started running in the simplest and usual way, to print
  66     an announcement including a valid copyright notice
  67     "Copyright (C) 1986 Free Software Foundation, Inc." (or with
  68     the year updated if appropriate), saying that there
  69     is no warranty (or else, saying that you provide
  70     a warranty) and that users may redistribute the program under
  71     these conditions, and telling the user how to view a copy of
  72     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   3. You may copy and distribute GDB or any portion of it in
  79 compiled, executable or object code form under the terms of Paragraphs
  80 1 and 2 above provided that you do the following:
  81
  82     a) cause each such copy to be accompanied by the
  83     corresponding machine-readable source code, which must
  84     be distributed under the terms of Paragraphs 1 and 2 above; or,
  85
  86     b) cause each such copy to be accompanied by a
  87     written offer, with no time limit, to give any third party
  88     free (except for a nominal shipping charge) a machine readable
  89     copy of the corresponding source code, to be distributed
  90     under the terms of Paragraphs 1 and 2 above; or,
  91
  92     c) in the case of a recipient of GDB in compiled, executable
  93     or object code form (without the corresponding source code) you
  94     shall cause copies you distribute to be accompanied by a copy
  95     of the written offer of source code which you received along
  96     with the copy you received.
  97
  98   4. You may not copy, sublicense, distribute or transfer GDB
  99 except as expressly provided under this License Agreement.  Any attempt
 100 otherwise to copy, sublicense, distribute or transfer GDB is void and
 101 your rights to use the program under this License agreement shall be
 102 automatically terminated.  However, parties who have received computer
 103 software programs from you with this License Agreement will not have
 104 their licenses terminated so long as such parties remain in full compliance.
 105
 106   5. If you wish to incorporate parts of GDB into other free
 107 programs whose distribution conditions are different, write to the Free
 108 Software Foundation at 675 Mass Ave, Cambridge, MA 02139.  We have not yet
 109 worked out a simple rule that can be stated here, but we will often permit
 110 this.  We will be guided by the two goals of preserving the free status of
 111 all derivatives of our free software and of promoting the sharing and reuse
 112 of software.
 113
 114 In other words, go ahead and share GDB, but don't try to stop
 115 anyone else from sharing it farther.  Help stamp out software hoarding!
 116
 117                        NO WARRANTY
 118
 119   BECAUSE GDB IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY NO
 120 WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW.  EXCEPT
 121 WHEN OTHERWISE STATED IN WRITING, FREE SOFTWARE FOUNDATION, INC,
 122 RICHARD M. STALLMAN AND/OR OTHER PARTIES PROVIDE GDB "AS IS" WITHOUT
 123 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
 124 LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
 125 A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND
 126 PERFORMANCE OF GDB IS WITH YOU.  SHOULD GDB PROVE DEFECTIVE, YOU
 127 ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
 128
 129  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL RICHARD M.
 130 STALLMAN, THE FREE SOFTWARE FOUNDATION, INC., AND/OR ANY OTHER PARTY
 131 WHO MAY MODIFY AND REDISTRIBUTE GDB AS PERMITTED ABOVE, BE LIABLE TO
 132 YOU FOR DAMAGES, INCLUDING ANY LOST PROFITS, LOST MONIES, OR OTHER
 133 SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
 134 INABILITY TO USE (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
 135 BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY THIRD PARTIES OR A
 136 FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS) GDB, EVEN
 137 IF YOU HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR
 138 ANY CLAIM BY ANY OTHER PARTY.
