  30   1. You may copy and distribute verbatim copies of this source file
  31 as you receive it, in any medium, provided that you conspicuously and
  32 appropriately publish on each copy a valid copyright notice "Copyright
  33  (C) 1988 Free Software Foundation, Inc."; and include following the
  34 copyright notice a verbatim copy of the above disclaimer of warranty
  35 and of this License.  You may charge a distribution fee for the
  36 physical act of transferring a copy.
  37
  38   2. You may modify your copy or copies of this source file or
  39 any portion of it, and copy and distribute such modifications under
  40 the terms of Paragraph 1 above, provided that you also do the following:
  41
  42     a) cause the modified files to carry prominent notices stating
  43     that you changed the files and the date of any change; and
  44
  45     b) cause the whole of any work that you distribute or publish,
  46     that in whole or in part contains or is a derivative of this
  47     program or any part thereof, to be licensed at no charge to all
  48     third parties on terms identical to those contained in this
  49     License Agreement (except that you may choose to grant more extensive
  50     warranty protection to some or all third parties, at your option).
  51
  52     c) You may charge a distribution fee for the physical act of
  53     transferring a copy, and you may at your option offer warranty
  54     protection in exchange for a fee.
  55
  56 Mere aggregation of another unrelated program with this program (or its
  57 derivative) on a volume of a storage or distribution medium does not bring
  58 the other program under the scope of these terms.
  59
  60   3. You may copy and distribute this program or any portion of it in
  61 compiled, executable or object code form under the terms of Paragraphs
  62 1 and 2 above provided that you do the following:
  63
  64     a) accompany it with the complete corresponding machine-readable
  65     source code, which must be distributed under the terms of
  66     Paragraphs 1 and 2 above; or,
  67
  68     b) accompany it with a written offer, valid for at least three
  69     years, to give any third party free (except for a nominal
  70     shipping charge) a complete machine-readable copy of the
  71     corresponding source code, to be distributed under the terms of
  72     Paragraphs 1 and 2 above; or,
  73
  74     c) accompany it with the information you received as to where the
  75     corresponding source code may be obtained.  (This alternative is
  76     allowed only for noncommercial distribution and only if you
  77     received the program in object code or executable form alone.)
  78
  79 For an executable file, complete source code means all the source code for
  80 all modules it contains; but, as a special exception, it need not include
  81 source code for modules which are standard libraries that accompany the
  82 operating system on which the executable file runs.
  83
  84   4. You may not copy, sublicense, distribute or transfer this program
  85 except as expressly provided under this License Agreement.  Any attempt
  86 otherwise to copy, sublicense, distribute or transfer this program is void and
  87 your rights to use the program under this License agreement shall be
  88 automatically terminated.  However, parties who have received computer
  89 software programs from you with this License Agreement will not have
  90 their licenses terminated so long as such parties remain in full compliance.
  91
  92   5. If you wish to incorporate parts of this program into other free
  93 programs whose distribution conditions are different, write to the Free
  94 Software Foundation at 675 Mass Ave, Cambridge, MA 02139.  We have not yet
  95 worked out a simple rule that can be stated here, but we will often permit
  96 this.  We will be guided by the two goals of preserving the free status of
  97 all derivatives our free software and of promoting the sharing and reuse of
  98 software.
