There is the GNU info system. For example if you are curious about libc try:

- How do I know a problem has been reported?
-
Generally it is better to assume that a problem has not been reported. This is especially true with stuff that has been broken for a couple days. If you'd expect that something could be fixed quickly and it hasn't been, then odds are nobody has reported the problem.
- How can I get human help?
-
1. Stop by Olsen 312.
3. Send email to help AT cs.uml.edu.
Generally you'll get quicker results by asking the folks in 312 first. If you want help at 3 a.m., or want more than one person to attempt a solution, try sending email to help AT cs.uml.edu.
- What if there is nobody in Olsen 312?
-
If it's between 9am and 5pm it is likely that staff is in a lab or office working on a problem. Try sending email to help AT cs.uml.edu with your location for the next hour or so, or check back in 30 minutes. If it is after 5 PM or on the weekend, e-mail help AT cs.uml.edu .
- When will I get a reply to email sent to help AT cs.uml.edu?
-
You will get an automated answer saying the request was delivered, an email when it is solved and possibly another email explaining things further if needed.
