Where Does Free Software End and UNIX Begin?

You may find that some of the programs on the disc are already available at your site. After all, UNIX itself is already a collection of free software (). For example, here are just a few of the now-standard programs that were once contributed to UNIX (most through the University of California at Berkeley's BSD version):

• the C shell ()
• vi ()
• termcap ()

Here are some other programs that are nearly universally available (and official parts of some versions of UNIX, but not all):

• RCS ()
• gzip ()
• patch ()
• Emacs ()
• cut () and paste ()

We wanted to make sure that you had all the great programs in the second group, so we've included them just to be sure.
