+@unnumbered Copying Conditions
+@center (Clarified 11 Feb 1988)
+
+The license agreements of most software companies keep you at the mercy of
+those companies. By contrast, our general public license is intended to
+give everyone the right to share GNU Make. To make sure that you get the
+rights we want you to have, we need to make restrictions that forbid anyone
+to deny you these rights or to ask you to surrender the rights. Hence this
+license agreement.
+
+Specifically, we want to make sure that you have the right to give away
+copies of GNU Make, that you receive source code or else can get it if you
+want it, that you can change GNU Make or use pieces of it in new free
+programs, and that you know you can do these things.
+
+To make sure that everyone has such rights, we have to forbid you to
+deprive anyone else of these rights. For example, if you distribute copies
+of GNU Make, you must give the recipients all the rights that you have.
+You must make sure that they, too, receive or can get the source code. And
+you must tell them their rights.
+
+Also, for our own protection, we must make certain that everyone finds out
+that there is no warranty for GNU Make. If GNU Make is modified by someone
+else and passed on, we want its recipients to know that what they have is
+not what we distributed, so that any problems introduced by others will not
+reflect on our reputation.
+
+Therefore we (Richard Stallman and the Free Software Foundation,
+Inc.) make the following terms which say what you must do to be
+allowed to distribute or change GNU Make.
+
+@unnumberedsec Copying Policies
+
+@enumerate
+@item
+You may copy and distribute verbatim copies of GNU Make source code as
+you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy a valid copyright notice
+``Copyright @copyright{} 1988 Free Software Foundation, Inc.'' (or
+with whatever year is appropriate), and include following the
+copyright notice a verbatim copy of the above disclaimer of warranty
+and of this License. You may charge a distribution fee for the
+physical act of transferring a copy.
+
+@item
+You may modify your copy or copies of GNU Make or any portion of it,
+and copy and distribute such modifications under the terms of
+Paragraph 1 above, provided that you also do the following:
+
+@itemize @bullet
+@item
+cause the modified files to carry prominent notices stating
+that you changed the files and the date of any change; and
+
+@item
+cause the whole of any work that you distribute or publish, that
+in whole or in part contains or is a derivative of Bison or any
+part thereof, to be licensed at no charge to all third parties on
+terms identical to those contained in this License Agreement
+(except that you may choose to grant more extensive warranty
+protection to some or all third parties, at your option).
+
+@item
+You may charge a distribution fee for the physical act of
+transferring a copy, and you may at your option offer warranty
+protection in exchange for a fee.
+@end itemize
+
+Mere aggregation of another unrelated program with this program (or its
+derivative) on a volume of a storage or distribution medium does not bring
+the other program under the scope of these terms.
+
+@item
+You may copy and distribute GNU Make (or a portion or derivative of it,
+under Paragraph 2) in object code or executable form under the terms
+of Paragraphs 1 and 2 above provided that you also do one of the
+following:
+
+@itemize @bullet
+@item
+accompany it with the complete corresponding machine-readable
+source code, which must be distributed under the terms of
+Paragraphs 1 and 2 above; or,
+
+@item
+accompany it with a written offer, valid for at least three
+years, to give any third party free (except for a nominal
+shipping charge) a complete machine-readable copy of the
+corresponding source code, to be distributed under the terms of
+Paragraphs 1 and 2 above; or,
+
+@item
+accompany it with the information you received as to where the
+corresponding source code may be obtained. (This alternative is
+allowed only for noncommercial distribution and only if you
+received the program in object code or executable form alone.)
+@end itemize
+
+For an executable file, complete source code means all the source code
+for all modules it contains; but, as a special exception, it need not
+include source code for modules which are standard libraries that
+accompany the operating system on which the executable file runs.
+
+@item
+You may not copy, sublicense, distribute or transfer GNU Make except as
+expressly provided under this License Agreement. Any attempt
+otherwise to copy, sublicense, distribute or transfer GNU Make is void
+and your rights to use the program under this License agreement shall
+be automatically terminated. However, parties who have received
+computer software programs from you with this License Agreement will
+not have their licenses terminated so long as such parties remain in
+full compliance.
+
+@item
+If you wish to incorporate parts of GNU Make into other free programs
+whose distribution conditions are different, write to the Free Software
+Foundation at 675 Mass Ave, Cambridge, MA 02139. We have not yet worked
+out a simple rule that can be stated here, but we will often permit this.
+We will be guided by the two goals of preserving the free status of all
+derivatives of our free software and of promoting the sharing and reuse of
+software.
+@end enumerate
+
+Your comments and suggestions about our licensing policies and our
+software are welcome! Please contact the Free Software Foundation, Inc.,
+675 Mass Ave, Cambridge, MA 02139, or call (617) 876-3296.
+
+@unnumberedsec NO WARRANTY
+
+ BECAUSE GNU MAKE IS LICENSED FREE OF CHARGE, WE PROVIDE ABSOLUTELY NO
+WARRANTY, TO THE EXTENT PERMITTED BY APPLICABLE STATE LAW. EXCEPT
+WHEN OTHERWISE STATED IN WRITING, THE FREE SOFTWARE FOUNDATION, INC,
+RICHARD M. STALLMAN AND/OR OTHER PARTIES PROVIDE GNU MAKE "AS IS" WITHOUT
+WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
+LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
+A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
+PERFORMANCE OF GNU MAKE IS WITH YOU. SHOULD GNU MAKE PROVE DEFECTIVE, YOU
+ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL RICHARD M.
+STALLMAN, THE FREE SOFTWARE FOUNDATION, INC., AND/OR ANY OTHER PARTY
+WHO MAY MODIFY AND REDISTRIBUTE GNU MAKE AS PERMITTED ABOVE, BE LIABLE TO
+YOU FOR DAMAGES, INCLUDING ANY LOST PROFITS, LOST MONIES, OR OTHER
+SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
+INABILITY TO USE (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
+BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY THIRD PARTIES OR A
+FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS) GNU MAKE, EVEN
+IF YOU HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, OR FOR
+ANY CLAIM BY ANY OTHER PARTY.
