Name the package(s) with the best documentation

[aleph]

This post is inspired by a recent Slashdot story about the general pathetic state of Linux documentation. When skimming through the usual hate-spitting comments there, I thought, well why not take the half-full angle and see what we could learn from the Really Good (TM) docs?

So here guys, let's name the best documentations of your choice here and share the joy. For the sake of relevance I recommend confining the discussion within the range of:

* Fedora, or at least Linux, software,
* "Official" docs (man pages, online help/tutorial, etc. That's excluding wikis, mailing lists, Usenet groups, or Web forums etc.)

And of course you're free to break these rules

Those complaining should really get themselves into a M$ or Oracle project with little time to market and a need to brush up their knowledge: Then they would discover new meanings for the word "trouble"

P.S. Just to prove that I'm not entirely polemic, I'd vow for all GNU documentation. I think it's excellent

The xlogo man page is excellent.

FreeBSD jail man page
Fluxbox man page

Re MS. If someone has almost no knowledge of AD, and has to put a user into a new group, they can click help on a Windows server put in something like add user to group and get a clear step by step guide of how to do it.

If the situation is reversed, and an MS admin has to do it for a Samba setup, I've yet to see help that would do it as well. (However, I don't use GUI tools for Samba, maybe it's improved.)

For the everyday tasks, MS documentation is not only centralized, but quite useful.
