+Free Unix!
+
+Starting this Thanksgiving I am going to write a complete
+Unix-compatible software system called GNU (for Gnu's Not Unix), and
+give it away free to everyone who can use it.  Contributions of time,
+money, programs and equipment are greatly needed.
+
+To begin with, GNU will be a kernel plus all the utilities needed to
+write and run C programs: editor, shell, C compiler, linker,
+assembler, and a few other things.  After this we will add a text
+formatter, a YACC, an Empire game, a spreadsheet, and hundreds of
+other things.  We hope to supply, eventually, everything useful that
+normally comes with a Unix system, and anything else useful, including
+on-line and hardcopy documentation.
+
+GNU will be able to run Unix programs, but will not be identical
+to Unix.  We will make all improvements that are convenient, based
+on our experience with other operating systems.  In particular,
+we plan to have longer filenames, file version numbers, a crashproof
+file system, filename completion perhaps, terminal-independent
+display support, and eventually a Lisp-based window system through
+which several Lisp programs and ordinary Unix programs can share a screen.
+Both C and Lisp will be available as system programming languages.
+We will have network software based on MIT's chaosnet protocol,
+far superior to UUCP.  We may also have something compatible
+with UUCP.
+
+
+Who Am I?
+
+I am Richard Stallman, inventor of the original much-imitated EMACS
+editor, now at the Artificial Intelligence Lab at MIT.  I have worked
+extensively on compilers, editors, debuggers, command interpreters, the
+Incompatible Timesharing System and the Lisp Machine operating system.
+I pioneered terminal-independent display support in ITS.  In addition I
+have implemented one crashproof file system and two window systems for
+Lisp machines.
+
+
+Why I Must Write GNU
+
+I consider that the golden rule requires that if I like a program I
+must share it with other people who like it.  I cannot in good
+conscience sign a nondisclosure agreement or a software license
+agreement.
+
+So that I can continue to use computers without violating my principles,
+I have decided to put together a sufficient body of free software so that
+I will be able to get along without any software that is not free.
+
+
+How You Can Contribute
+
+I am asking computer manufacturers for donations of machines and money.
+I'm asking individuals for donations of programs and work.
+
+One computer manufacturer has already offered to provide a machine.  But
+we could use more.  One consequence you can expect if you donate
+machines is that GNU will run on them at an early date.  The machine had
+better be able to operate in a residential area, and not require
+sophisticated cooling or power.
+
+Individual programmers can contribute by writing a compatible duplicate
+of some Unix utility and giving it to me.  For most projects, such
+part-time distributed work would be very hard to coordinate; the
+independently-written parts would not work together.  But for the
+particular task of replacing Unix, this problem is absent.  Most
+interface specifications are fixed by Unix compatibility.  If each
+contribution works with the rest of Unix, it will probably work
+with the rest of GNU.
+
+If I get donations of money, I may be able to hire a few people full or
+part time.  The salary won't be high, but I'm looking for people for
+whom knowing they are helping humanity is as important as money.  I view
+this as a way of enabling dedicated people to devote their full energies to
+working on GNU by sparing them the need to make a living in another way.
