"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.
