I can see online some documentation >speaking about (on oracle website) and even some crazy french website saying it >worked with groff, but can't find the file in groff history either The troff output was invented at Sun and the online docs for some post-SunOS operating system include this: The usual way to get a troffed listing is with the command indent -troff program.c | troff -mindent The indent manpage in FreeBSD 1.0 already lacks that information and troff -mindent complains about not being able to find the macro file. So I guess the file did exist on SunOS and was supposed to be imported into 4.3BSD together with the feature, but wasn't.help
