Hi folks, I'm trying to clear up a historical matter.
In reviewing groff's "LICENSES" file, I find myself stuck on the following paragraph. >grn, written by Barry Roitblat <ba...@rentonww.com> and David >Slattengren <slatt...@xinet.com>, was part of the Berkeley >troff distribution. The files contain no AT&T code >and are in the public domain. Historically, the original package could >be found at <http://ftp.cs.wisc.edu/pub/misc/grn.tar.Z>. I'm not sure about that reference to "Berkeley troff". I already deleted the modifier "device-independent" from that sentence because I've never seen even a whisper of evidence that the CSRG ever distributed Kernighan's device-independent troff; that was locked up behind AT&T's revenue-seeking aims. But also, I can't find evidence that "grn" was distributed by Berkeley at all. At Warren's "Unix Tree",[1] I see what looks superficially like evidence of support for Gremlin terminals in "libplot", but that's not the same thing. However there is evidence of support for grn, the troff preprocessor, in other unquestionable BSD artifacts, like Eric Allman's "me" package. Can someone clear up my misconceptions or suggest non-misleading alternative wording? Was the grn preprocessor one of these "USENIX tape" things, like nethack and jove?
