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

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

Expand *n't contractions.

Sort sections.

Eliminate double whitespace.

POSIX prohibits any library function from setting errno to 0.
Correct my previous commit and add a comment to the manpage
indicating that the user must set errno to 0 if they wish to
distinguish "no such user" from "error".

mdoc(7): Use the new feature of the .In macro.

Add or correct section number in .Xr. Use .Vt or .Fn
instead of .Xr when needed

Assorted mdoc(7) fixes.

Approved by: re (blanket)

= Implement thread-safe versions of the getpwent(3) and getgrent(3)
family of functions using the new nsdispatch(3) core. Remove
arbitrary size limits when using the thread-safe versions.

= Re-implement the traditional getpwent(3)/getgrent(3) functions on
top of the thread-safe versions.

= Update the on-disk format of the hashed version of the passwd(5)
databases to allow for versioned entries. The legacy version is
`3'. (Don't ask.)

= Add support for version `4' entries in the passwd(5) database.
Entries in this format are identical to version 3 entries except
that all integers are stored as 32-bit integers in network byte
order (big endian).

= pwd_mkdb is updated to generate both version 3 and version 4
entries.

mdoc(7) police: Fixed abuses of the .Ar and .Em macros.

mdoc(7) police: "The .Fn function".

yp(4) -> yp(8).

PR: docs/30797

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

mdoc(7) police: protect trailing full stops of abbreviations
with a trailing zero-width space: `e.g.\&'.

mdoc(7) police: split punctuation characters + misc fixes.

Add a period missing from rev 1.13.

Whitespace only change: trim trailing whitespace.

Add nsswitch support. By creating an /etc/nsswitch.conf file, you can
configure FreeBSD so that various databases such as passwd and group can be
looked up using flat files, NIS, or Hesiod.

= Hesiod has been added to libc (see hesiod(3)).

= A library routine for parsing nsswitch.conf and invoking callback
functions as specified has been added to libc (see nsdispatch(3)).

= The following C library functions have been modified to use nsdispatch:
. getgrent, getgrnam, getgrgid
. getpwent, getpwnam, getpwuid
. getusershell
. getaddrinfo
. gethostbyname, gethostbyname2, gethostbyaddr
. getnetbyname, getnetbyaddr
. getipnodebyname, getipnodebyaddr, getnodebyname, getnodebyaddr

= host.conf has been removed from src/etc. rc.network has been modified
to warn that host.conf is no longer used at boot time. In addition, if
there is a host.conf but no nsswitch.conf, the latter is created at boot
time from the former.

Introduce ".Lb" macro to libc manpages.

More libraries manpages updates following.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Use the correct type for uid and gid in struct passwd. Document it.

Cleanup the manpage now that setpwent has a void return type.

Update to reflect current include files.

Update a bunch of man pages to use .Fn instead
of .Nm when referencing funciton names.

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.

Added some missing MLINKS for section 3 man pages.
Also corrected a few minor formatting errors, file location and cross
references in some of the section 3 man pages.

This shuts up a lot of the output from "manck" for section 3.

Document YP support.
