+ The problem is almost always interaction between NNTP and C News. NNTP

+ article.
+
+ My preferred solution is to change inews to not call relaynews, but
+ rather use newsspool. This loses some error-catching functionality, but

GNU Emacs FAQ: Introduction
[To find what has changed, see the "diff" posting.]
[Joe Wells plans to quit soon as FAQ coordinator. Steven Byrnes says he can
take over this portion of the FAQ responsibility. We still need more
volunteers to help by taking charge of a section of the FAQ list. Send e-mail
if you are interested.]
This is the introduction to a list of frequently asked questions (FAQ) about
GNU Emacs with answers. This article contains a listing of the questions;
subsequent articles contain the questions and answers.
The FAQ list is posted to reduce the noise level in the `gnu.emacs.help'
newsgroup (which is also the `help-gnu-emacs' mailing list) which results from
the repetition of frequently asked questions, wrong answers to these questions,
corrections to the wrong answers, corrections to the corrections, debate, name
calling, etc. Also, it serves as a repository of the canonical "best" answers
to these questions. However, if you know a better answer or even a slight
change that improves an answer, please tell us!
If you know the answer of a question is in the FAQ list, please reply to the
question by e-mail instead of posting. Help reduce noise!
The FAQ list is crossposted to `comp.emacs' because some sites do not receive
the `gnu.*' newsgroups. The FAQ list is also crossposted to `news.answers'.
Please suggest new questions, answers, wording changes, deletions, etc. The
most helpful form for suggestions is a context diff (ie., the output of `diff
-c'). Include `FAQ' in the subject of messages sent to us about the FAQ list.
Please do not send questions to us just because you do not want to disturb a
lot of people and you think we would know the answer. We do not have time to
answer questions individually. :-(
Full instructions for getting the latest FAQ are in question 22. Also see the
`Introduction to news.answers' posting in the `news.answers' newsgroup, or send
e-mail to `mail-server@rtfm.mit.edu' with `help' on a body line, or use FTP,
WAIS, or Prospero to rtfm.mit.edu.
These ideas have already been suggested, but we have not had time to
implement them:
* A Texinfo version.
* Marking questions in the table of contents that have been changed
recently.

GNU Emacs FAQ: Notation/General/Help/Status
If you are viewing this text in a GNU Emacs Buffer, you can type "M-2 C-x $" to
get an overview of just the questions. Then, when you want to look at the text
of the answers, just type "C-x $".
To search for a question numbered XXX, type "M-C-s ^XXX:", followed by a C-r if
that doesn't work, then type ESC to end the search.
A `+' in the 78th column means something was inserted on the line. A `-' means
something was deleted and a `!' means some combination of insertions and
deletions occurred.
Full instructions for getting the latest FAQ are in question 22. Also see the
`Introduction to news.answers' posting in the `news.answers' newsgroup, or send

later answers.
1: What do these mean: C-h, M-C-a, RET, "ESC a", etc.?
C-x means press the `x' key while holding down the Control key. M-x means
press the `x' key while holding down the Meta key. M-C-x means press the
`x' key while holding down both the Control key and the Meta key. C-M-a
is a synonym for M-C-a. RET, LFD, DEL, ESC, and TAB respectively refer to
pressing the Return, Linefeed (aka Newline), Delete, Escape, and Tab keys
and are equivalent to C-m, C-j, C-?, C-[, and C-i. SPC means press the
Space bar.
I put any key sequence that is longer than one key (and some single-key
sequences) inside double quotes or on a line by itself. Any real spaces
in such a key sequence should be ignored; only SPC really means press the
space key.
The ASCII code sent by C-x (except for C-?) is the value that would be
sent by pressing just `x' minus 96 (or 64 for uppercase `X') and will be
from 0 to 31. The ASCII code sent by M-x is the sum of 128 and the ASCII
code that would be sent by pressing just the `x' key. Essentially, the
Control key turns off bits 5 and 6 and the Meta key turns on bit 7.
For further information, see `Characters' and `Keys' in the online manual.
NOTE: C-? (aka DEL) is ASCII code 127. It is a misnomer to call C-? a
"control" key, since 127 has both bits 5 and 6 turned ON. Also, on very
few keyboards does Control-? generate ASCII code 127.
2: What does "M-x command" mean?
"M-x command" means type M-x, then type the name of the command, then
type RET.
M-x (by default) invokes the command `execute-extended-command'. This
command allows you to run any Emacs command if you can remember the
command's name. If you can't remember the command's name, you can type
TAB and SPC for completion, and "?" for a list of possibilities. An Emacs
"command" is any "interactive" Emacs function.
NOTE: Your system administrator may have bound other key sequences to
invoke execute-extended-command. A function key labeled `Do' is a good
candidate for this.
To run non-interactive Emacs functions, see question 53.
3: How do I read topic XXX in the on-line manual?
When I refer you to topic XXX in the on-line manual, you can read this
manual node inside Emacs (assuming nothing is broken) by typing this:
C-h i m emacs RET m XXX RET
This invokes the Info facility. If you don't already know how to use
Info, type "?" from within Info.
If I refer you to topic XXX:YYY, you need to type this:
C-h i m emacs RET m XXX RET m YYY RET
WARNING: Your system administrator may not have installed the Info files,
or may have installed them properly. In this case you should complain.
4: What do these mean: etc/SERVICE, src/config.h, lisp/default.el?
These are files that come with GNU Emacs. The GNU Emacs distribution is
divided into subdirectories; the important ones are `etc', `lisp', and
`src'.
If you use GNU Emacs, but don't know where it is kept on your system,
start Emacs, then type "C-h v exec-directory RET". The directory name
displayed by this will be the full pathname of the installed `etc'
directory.
Some of these files are available individually via FTP or e-mail, see
question 20. All are available in the source distribution.
5: What are FSF, LPF, OSF, GNU, RMS, FTP, and GPL?
FSF == Free Software Foundation
LPF == League for Programming Freedom
OSF == Open Software Foundation
GNU == GNU's Not Unix
RMS == Richard Matthew Stallman
FTP == File Transfer Protocol
GPL == GNU General Public Licence
NOTE: Avoid confusing the FSF, the LPF, and the OSF. The LPF opposes
look-and-feel copyrights and software patents. The FSF aims to make high
quality free software available for everyone. The OSF is a commercial
organization which wants to provide an alternative, standardized version
of Unix not controlled by AT&T.
NOTE: The word "free" in the title of the Free Software Foundation refers
to "freedom", not "zero dollars". Anyone can charge any price for
GPL-covered software that they want to. However, in practice, the freedom
enforced by the GPL leads to low prices, because you can always get the
software for less money from someone else, because everyone has the right
to resell or give away GPL-covered software.
General Questions
6: What is the LPF and why should I join it?
The LPF opposes the expanding danger of software patents and look-and-feel
copyrights. To get more information, feel free to contact the LPF via
e-mail or otherwise. {You may also contact me, jbw@cs.bu.edu; I will be
happy to talk with you about the LPF.} Here is the contact information: !
