Relay-Version:version B 3/9/83; site harpo.UUCP Message-ID:<410@rlgvax.UUCP> Date:Wed, 11-May-83 11:20:27 EDT Back in the old days, for non-Bell people, there was V6 UNIX. The next release was PWB UNIX, with several changes: 'troff' was added, (and 'nroff' became a compile-time option of 'troff'), there was a new C compiler (new constructs were longs, unsigneds, castings, etc.), a new archiver, a new link-editor (to go with the archiver), a new tape program ('cpio'), the 'stdio' package, and of course 'make', 'sccs', and the better UNIX configuration tools that we normally associate with PWB. "Phototypesetter UNIX", or "Phototypesetter C", was an in-between release, which you put on top of V6 and provided some of the tools from PWB. In particular it gave 'troff' and the new 'nroff' (hence the name). It also provided the new C compiler, archiver, link-editor, and 'stdio' (probably so you could compile 'troff'), and a few other odds and ends, but not SCCS or 'make'. For anyone with a V6 UNIX system, this upgrade is virtually mandatory since the tools are much more compatible with the rest of the UNIX world than straight V6. The V6 compiler does not support many things used in everyday C programs which Phototypesetter C does. V6 doesn't have 'stdio', the most important portability tool around, but Phototypsetter does. 'Cpio' is worlds better than 'tp' (and many might argue better than 'tar'). And V6 nroff has incompatibilities with other nroffs, and so many bugs that it is best avoided for any complex formatting. Phototypsetter C/UNIX does not help anyone with a PWB System, since it is a subset of PWB. This moment in history brought to you by ... Tom Beres RLG Corp. {we13, seismo, allegra, mcnc}!rlgvax!tom
