In example use of err(3) and errx(3), use sysexits(3) constants.

Per Regents of the University of Calfornia letter, remove advertising
clause.

# If I've done so improperly on a file, please let me know.

Minor clarification.

Markup nit.

Mutually cross-reference sysexits(3) and err(3). Add text to err(3)
recommending that the standard exit codes in sysexits(3) be used.

Implement POSIX.1-2001 (XSI)'s fmtmsg(3).

mdoc(7) police: Use the new .In macro for #include statements.

mdoc(7) police: removed HISTORY info from the .Os call.

Preceed/preceeding are not english words. Use precede or preceding.

mdoc(7) police: use canonical form of .Dd macro.

Note that the `fmt' parameter is a printf()-like string.

Describe errx/warnx in comparison to errc/warnc/err/warn.
Use .Fa instead of .Va for function arguments.

Introduce ".Lb" macro to libc manpages.

More libraries manpages updates following.

$Id$ -> $FreeBSD$

Don't bogotify the synopsis by attempting to describe err_set_file() there.

Fixed some disorder.

A small last-minute iitem for 3.0:

- Fix some style errors I made back in 1995.

- Add a new flavor of the err(3) family, which takes an explicit
errno argument rather than implicitly examining errno. This
will make it easier to use these functions in conjunction with
modern library interfaces that return an errno value explicitly.

Improve description.

Added missing #include of <stdarg.h> to synopsis. Moved prototypes for
`v' functions after this #include (same organisation as in printf.3 for
printf/vprintf).

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Correctly use .Fn instead of .Nm to reference function names
in a bunch of man pages.

Use the correct .Bx (BSD UNIX) or .At (AT&T UNIX) macros
instead of explicitly specifying the version in the text
in a bunch of man pages.

Correct a bunch of man page cross references and generally
try and silence "manck".

ncurses, rpc, and some of the gnu stuff are still a big mess, however.

Add err_set_file() and err_set_exit() functions to make it possible for
programs which use err(3) to work nicely in a wider range of environments
(e.g., dialog).
