What is not clear about that?

During parsing of what? What is parsing? What does it mean by "define"? "Current section" of what? Where are the names? Etc. Etc. ........

Parsing of what, current section of what? I thought the command used to read that file would give you a hint "man pacman.conf"...

And you seriously want "define" defined?

Discerning people understand that context is everything. Also, you seemed to be implying that you wanted examples. I gave you only some of them.

I find that most man pages are written for long term reference and it's not unreasonable for the authors to expect readers to need to reread them multiple times to pick up on certain subtleties. I think in this case, give that you are reading the manpage for pacman.conf, it is quite obvious that pacman is parsing pacman.conf. And given the *context* of the heading (Repository Sections), it's also quite obvious what sections we're talking about.

It is actually the opposite that determines the quality of writing; if a reader gets it during the first read, it is easily understood, and therefore properly written. This is even more important in situations where the purpose of the text is to act as a help file and to explain things for the benefit of the reader/user.

I actually did not get that explanation of parsing as you did. Interesting.

The context issue is an interesting one because it actually appears to be associated with the $repo variable.
It was good to learn, however indirectly, that the variable $repo is used repeatedly for each section name, in turn (if I get the gist of what you wrote). However, I now believe that to be wrong. I guess I now understand that what should have been written was "As the pacman program processes the information it finds in pacman.conf, it replaces the variable $repo with the address of the repository from each section it finds, in turn, from top to bottom, as it searches the repos thru the Internet for the file needed". But that appears to be only if it is in the Include directive. But then that brings up the question "Why have separate sections and not just put everything under the directive?".

Now please keep in mind that I understand that you may not want to target those who do not understand your inside language usage, and that's fine. But what does not make sense is when others wish to help clarify and make the file more useful to more people, that you people would use a tone that is very discouraging and unwelcoming. It's free help, for pity's sake! Where's the downside?

(Unless, that is, you really believe you've written a great man page.)
