Should I keep the static part of the COLOPHON in a REPORTING BUGS section?

I do not think a manual page should include *any* boilerplate text.
Text that is the same everywhere is nothing but a distraction
and a waste of screen real estate.

Agree.  I was hesitant of removing that, which mtk added a long time
ago, since he claimed an important improvement in awareness of the
existence of the project.  But I prefer using reportbug(1) and dpkg(1)
or apt(8) (or equivalent in other distros) to find out how to report bugs.

Hum.  Interesting aspect.  Maybe Micheal had a point that advertising
the Linux man-pages project - even in such an aggressive way - had some
value in the early days.  I'm not an expert in Linux history, but i
believe use of manual pages was initially much less common in Linux-
based operating systems compared to AT&T UNIX, other commercial UNIX
systems, and BSD.  Also, due to the fragmentation of Linux-based
operating systems into Linux (the kernel), GNU (the most important
parts of userland), and software from many third-party sources,
a single, uniform corpus of manual pages was slower to develop for
Linux than, for example, in BSD.

But nowadays, i would no longer subscribe to such a theory, it seems
to me that times have changed in this respect.  Debian has fostered
some progress in writing missing manual pages.  Web sites like
manpages.debian.org and even man.archlinux.org now provide more
comprehensive collections of manual pages than even BSDs do.
And such sites usually clearly identify package names, much reducing
the effects of the conceptual fragmentation.  So i expect many more
Linux users are now aware of the man-pages project than used to be,
and even those who aren't yet are likely to find out once they need to.

this time it seems your name and email are correct :)


Greg KH expressed concern about the copyright of the example programs
some time ago.  He asked what license applies to them, and how should a
user know, that is, is a user allowed to create derived programs from
those examples?  Should we state their license in a C comment within the
example program?  Or just assume that it's a meaningless program and
that anyone can just copy it indiscriminately because, who cares about
such a tiny insignificant piece of code?

That is an interesting question, too.  I believe it never occurred
to me because EXAMPLES in OpenBSD manual pages are typically kept so
short and simple that they only demonstrate well-established aspects
of prior art and do not really involve any creative act by the author
of the manual pages, hence obviously being in in the public domain
in the first place.

But in the Linux man-pages project, you have many long and complex
programs below EXAMPLES, some of which certainly pass the test of
originality, hence being protected by Copyright law.

Now obviously, unless otherwise stated, such examples are covered
by the SPDX-License-Identifier: at the top of the file.  For pages
licensed under the BSD or MIT licenses, everything is obviously
fine, anyone can use such example code in any project.  For pages
under GPL licenses, the situation is also tolerable: while BSD
projects cannot use these example, at least GPL projects can, which
feels like the main purpose of a Linux project.  I sense a real
problem with EXAMPLES in Linux-man-pages-copyleft pages though:
Those can *neither* be used in BSD projects *nor* in GPL projects
as far as i can see.

Maybe it would be worth finding the authors of significant examples
in Linux-man-pages-copyleft pages and getting their permission
to add a line like

   /* This example code is released into the public domain. */

at the top of such examples, maybe together with a roff(7) comment
like

   .\" This example code was written by Alice and Bob in 2015.

Anything more complicated, like refering to GPL-2+ would seem like
overkill to me.

I'll do that (PD) with all of my examples, and will also request a comment stating either PD or a specific license for contributions to EXAMPLES. For existing examples, since most come from Michael, I'll wait until he comes back some day, if he does... Otherwise, I'll just do nothing until someone asks for a license for a specific piece of code, and then ask the specific author.


AUTHORS,

[...]

I think it's a case-by-case decision: is there clear enough and
significant enough authorship of the initial version, or was it
a cast of many right from the start?

For now, since mtk was against that section, I'll keep that trend.

Cheers,

Alex


Yours,
   Ingo
