The topic array in the CHANNEL structure must be free()'d before the
channel itself becomes deleted.

-ngIRCd CVS-HEAD
+ngIRCd 0.12.1 (2008-07-09)
 
+  - Allow mixed line terminations (CR+LF/CR/LF) in non-RFC-compliant mode
+  - Don't allow stray \r or \n in command parameters
+  - --configtest: return non-zero exit code if there are errors
+  - Update ngIRCd manual pages
+  - Add option aliases -V (for --version) and -h (for --help).
+  - Fix 'no-ipv6' compile error.
+  - Make Listen parameter a comma-seperated list of addresses. This also
+    obsoletes ListenIPv4 and ListenIPv6 options. If Listen is unset, it
+    is treated as Listen="::,0.0.0.0".
+    Note: ListenIPv4 and ListenIPv6 options are still recognized,
+    but ngircd will print a warning if they are used in the config file.
+
+ngIRCd 0.12.0 (2008-05-13)
+
+  - Fix Bug: 85: "WHO #SecretChannel" that user is not a member of now returns
+    proper RPL_ENDOFWHO_MSG instead of nothing. (Ali Shemiran)
+  - Fix complie on FreeBSD 5.4 and AIX.
+  - If bind() fails, also print ip address and not just the port number.
+
+  ngIRCd 0.12.0-pre2 (2008-04-29)
+  - IPv6: Add config options to disabe ipv4/ipv6 support.
+  - Don't include doc/CVS.txt in distribution archive, use doc/GIT.txt now!
+  - Documentation: get rid of some more references to CVS, switch to GIT.
+  - Get rid of cvs-version.* and CVSDATE definition.
+  - Report ERR_NOTONCHANNEL when trying to part a channel one is not member of.
+  - Testsuite: remove erroneous ConfUID setting in config file.
+
+  ngIRCd 0.12.0-pre1 (2008-04-20)
+  - Include Mac OS X Xcode project in distribution archives.
+  - Do not exit on SIGHUP or /REHASH if the config file cannot opened.
+  - Add IPv6 support.
+  - Install a LaunchDaemon script to start/stop ngIRCd on Mac OS X.
+  - Implemented IRC commands INFO, SUMMON (dummy), and USERS (dummy) and
+    enhanced test suite to check these commands. (Dana Dahlstrom)
+  - RPL_WHOREPLY messages generated by IRC_WHO didn't include flags (*,@,+).
+    (Dana Dahlstrom)
+  - IRC_WHO now supports search patterns and will test this against user
+    nickname/servername/hostname, etc. as required by RFC 2812, Section 3.6.1.
+    (reported by Dana Dahlstrom)
+  - Add test cases for "WHO" command. (Dana Dahlstrom)
+  - Implement RFC 2812 handling of "0" argument to 'JOIN': must be treated
+    as if the user had sent PART commands for all channels the user is a
+    member of. (Dana Dahlstrom)
+  - Allow NOTICEs to be sent to a channel. (Fabian Schlager)
+
+ngIRCd 0.11.1 (2008-02-26)
+
+  - Fix sending of JOIN commands between servers when remote server appended
+    mode flags. (Rolf Eike Beer) [from HEAD]
+  - Send "G" instead of "H" flag in WHO replies. (reported by Dana Dahlstrom)
+  - Under some circumstances ngIRCd issued channel MODE message with a
+    trailing space. (Dana Dahlstrom) [from HEAD]
+
+ngIRCd 0.11.0 (2008-01-15)
+
+  ngIRCd 0.11.0-pre2 (2008-01-07)
+  - SECURITY: IRC_PART could reference invalid memory, causing
+    ngircd to crash [from HEAD].
+  
+  ngIRCd 0.11.0-pre1 (2008-01-02)
+  - Use dotted-decimal IP address if hostname is >= 64.
+  - Add support for /STAT u (server uptime) command.
+  - New [Server] configuration Option "Bind" allows to specify
+    the source ip adress to use when connecting to remote server.
+  - New configuration option "MaxNickLength" to specify the allowed maximum
+    length of user nick names. Note: must be unique in an IRC network!
+  - Enhanced the IRC+ protocol to support an enhanced "server handshake" and
+    enable server to recognice numeric 005 (ISUPPORT) and 376 (ENDOFMOTD).
+    See doc/Protocol.txt for details.
+  - Re-added doc/SSL.txt to distribution -- got lost somewhere!?
+  - Fixes the wrong logging output when nested servers are introduced
+    to the network as well as the wrong output of the LINKS command.
+  - Update Mac OS X Xcode project file for Xcode 3.
+  - Adjust test suite to be usable on HP/UX 11.11 :-)
+  - Fix code to compile using K&R C compiler and ansi2kr again.
+  - New config option NoDNS: Disables DNS lookups when clients connect.
+  - Fixed propagation of channel mode 'P' on server links.
+  - Numeric 317: implemented "signon time" (displayed in WHOIS result).
+  - Fixed code that prevented GCC 2.95 to compile ngIRCd.
+  - Adjust path names in manual pages according to "./configure" settings.
+  - Added new server configuration option "Passive" for "Server" blocks to
+    disable automatic outgoing connections (similar to -p option to ngircd,
+    but only for the specified server). (Tassilo Schweyer)
+  - Don't connect to a server if a connection to another server within the
+    same group is already in progress.
+  - Added support for the WALLOPS command. Usage is restricted to IRC
+    operators.
+
+ngIRCd 0.10.4 (2008-01-07)
+
+  - SECURITY: IRC_PART could reference invalid memory, causing
+    ngircd to crash [from HEAD].
+  
+ngIRCd 0.10.3 (2007-08-01)
+
+  - SECURITY: Fixed a severe bug in handling JOIN commands, which could
+    cause the server to crash. Thanks to Sebastian Vesper, <net@veoson.net>.
+
+ngIRCd 0.10.2 (2007-06-08)
+
+  ngIRCd 0.10.2-pre2 (2007-05-19)
+  - Server links are allowed to use larger write buffers now (up to 50 KB).
+
+  ngIRCd 0.10.2-pre1 (2007-05-05)
+  - Fix compressed server links (broken since 0.10.0).
+  - Predefined Channel configuration now allows specification of channel key
+    (mode k) and maximum user count (mode l).
+  - When using epoll() IO interface, compile in the select() interface as
+    well and fall back to it when epoll() isn't available on runtime.
+  - New configure option "--without-select" to disable select() IO API
+    (even when using epoll(), see above).
+  - Added support for IO APIs "poll()" and "/dev/poll".
+  - Reorganized internal handling of invite and ban lists.
+
+ngIRCd 0.10.1 (2006-12-17)
+
+  - Fixed validation of server names containing digits.
+  - Update the "info text" of the local server after re-reading configuration.
+  - Changed Numerics 265 and 266 to follow ircd 2.11.x "standards".
+  - Allow PASS syntax defined in RFC 1459 for server links, too.
+  - Enhanced ISUPPORT message (005 numeric).
+  - New configuration option "PredefChannelsOnly": if set, clients can only
+    join predefined channels.
+  - Code cleanups: use "LogDebug(...)" instead of "Log(LOG_DEBUG, ...)", use
+    "strcspn()", unsigned vs. signed, use "const", fix whitespaces, ...
+
+ngIRCd 0.10.0 (2006-10-01)
+
+  - Fixed file handle leak when daemon is not able to send MOTD to a client.
+
+  ngIRCd 0.10.0-pre2 (2006-09-09)
+  - Fixed build problems with GCC option -fstack-protector.
+  - Minor documentation updates.
+
+  ngIRCd 0.10.0-pre1 (2006-08-02)
+  - Validate "ServerName" (see RFC 2812, section 2.3.1).
+  - Enhanced DIE to accept a single parameter ("comment text") which is sent
+    to all locally connected clients before the server goes down.
+  - The ngIRCd handles time shifts backwards more gracefully now (the
+    timeout handling doesn't disconnect clients by mistake any more).
+  - Internal: Restructured connection handling (the connection ID is equal
+    to the file descriptor of the connection).
+  - Internal: Simplified resolver code.
+  - JOIN now supports more than one channel key at a time.
+  - Implemented numeric "333": Time and user name who set a channel topic.
+  - Enhanced the handler for PING and PONG commands: fix forwarding and enable
+    back-passing of a client supplied additional argument of PING.
+  - Changed handling of timeouts for unregistered connections: don't reset
+    the counter if data is received and disconnect clients earlier.
+  - Removed unnecessary #define of "LOCAL", now use plain C "static" instead.
+  - Channel topics are no longer limited to 127 characters: now the only limit
+    is the maximum length of an IRC command, i. e. 512 bytes (in practice, this
+    limits the topic to about 490 characters due to protocol overhead).
+  - Reverse DNS lookup code now checks the result by doing an additional
+    lookup to prevent spoofing.
+  - Added new IO layer which (optionally) supports epoll() and kqueue() in
+    addition to the select() interface.
+
+ngIRCd 0.9.2 (2005-10-15)
+
+  - Fixed a bug that could cause the daemon to crash when outgoing server
+    connections can't be established.
+  - Fixed a bug that caused the daemon to leak file descriptors when no
+    resolver subprocesses could be created.
+  - Fixed server NOTICEs to users with "s" mode ("server messages").
+  - Fixed a format string bug in "connection statistics" messages to clients.
+
+ngIRCd 0.9.1 (2005-08-03)
+
+  - The KILL command killed much more than desired (including server links!)
+    when the target user is connected to a remote server. Bug introduced in
+    ngIRCd 0.9.0 ...  Reported by <qssl@fastmail.fm>, Thanks!
+  - Changed some constants to be "signed" (instead of unsigned) to solve
+    problems with old (pre-ANSI) compilers.
+
+ngIRCd 0.9.0 (2005-07-24)
+
+  ngIRCd 0.9.0-pre1 (2005-07-09)
+  - Fixed maximum length of user names, now allow up to 9 characters.
+  - Cut off oversized IRC messages that should be sent to the network instead
+    of shutting down the (wrong) connection.
+  - Don't generate error messages for unknown commands received before the
+    client is registered with the server (like the original ircd).
+  - Never run with root privileges but always switch the user ID.
+  - Make "netsplit" messages RFC compliant.
+  - Fix handling of QUIT Messages: send only one message, even if the client
+    is member of multiple channels.
+  - Don't exit server if closing of a socket fails; instead ignore it and
+    pray that this will be "the right thing" ...
+  - Implemented the IRC function "WHOWAS".
+  - Don't enable assert() calls when not ./configure'd with --enable-debug.
+  - Fixed ./configure test for TCP Wrappers: now it runs on Mac OS X as well.
+  - Enhanced configure script: now you can pass an (optional) search path
+    to all --with-XXX parameters, e. g. "--with-ident=/opt/ident".
+  - Removed typedefs for the native C datatypes.
+    Use stdbool.h / inttypes.h if available.
+  - New configuration option "OperServerMode" to enable a workaround needed
+    when running an network with ircd2 servers and "OperCanUseMode" enabled
+    to prevent the ircd2 daemon to drop mode changes of IRC operators.
+    Patch by Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+  - Implemented support for "secret channels" (channel mode "s").
+  - New configuration option "Mask" for [Operator] sections to limit OPER
+    commands to users with a specific IRC mask. Patch from Florian Westphal.
+  - Write "error file" (/tmp/ngircd-XXX.err) only if compiled with debug
+    code ("--enable-debug") and running as daemon process.
+  - Don't create version information string each time a client connects
+    but instead on server startup. By Florian Westphal.
+  - New configuration variable "PidFile", section "[Global]": if defined,
+    the server writes its process ID (PID) to this file. Default: off.
+    Idea of Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+  - Code cleanups from Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+  - Raised the maximum length of passwords to 20 characters.
+  - Fixed a memory leak when resizing the connection pool and realloc()
+    failed. Now we don't fall back to malloc(), which should be sane anyway.
+    Patch from Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+  - Added support for the Howl (http://www.porchdogsoft.com/products/howl/)
+    Rendezvous API, in addition to the API of Apple (Mac OS X). The available
+    API will be autodetected when you call "./configure --with-rendezvous".
+  - Made ngIRCd compile on HP/UX 10.20 with native HP pre-ANSI C compiler and
+    most probably other older C compilers on other systems.
+  - When the daemon should switch to another user ID (ServerID is defined in
+    the configuration file) and is not running in a chroot environment, it
+    changes its working directory to the home directory of this user. This
+    should enable the system to write proper core files when not running with
+    root privileges ...
+
+ngIRCd 0.8.3 (2005-02-03)
+
+  - Fixed a bug that could case a root exploit when the daemon is compiled
+    to do IDENT lookups and is logging to syslog. Bug discovered by CoKi,
+    <coki@nosystem.com.ar>, thanks a lot!
+    (http://www.nosystem.com.ar/advisories/advisory-11.txt)
+
+ngIRCd 0.8.2 (2005-01-26)
+
+  - Added doc/SSL.txt to distribution.
+  - Fixed a buffer overflow that could cause the daemon to crash. Bug found
+    by Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+  - Fixed a possible buffer underrun when reading the MOTD file. Thanks
+    to Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+  - Fixed detection of IRC lines which are too long to send. Detected by
+    Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+  - Fixed return values of our own implementation of strlcpy(). The code has
+    been taken from rsync and they fixed it, but we didn't until today :-/
+    It has only been used when the system didn't implement strlcpy by itself,
+    not on "modern" systems. Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+
+ngIRCd 0.8.1 (2004-12-25)
+
+  - Autoconf: Updated config.guess and config.sub
+  - Added some more debug code ...
+  - Fixed wrong variable names in output of "ngircd --configtest".
+  - Debian: Fixed the name of the "default file" in the init script for
+    ngircd-full packages. And do the test if the binary is executable after
+    reading this file.
+  - Enhanced the "test suite": please have a look at src/testsuite/README!
+
+ngIRCd 0.8.0 (2004-06-26)
+
+  - Fixed wrong buffer size calculation for results of the resolver.
+
+  ngircd 0.8.0-pre2 (2004-05-16)
+  - Enhanced logging to console when running in "no-detached mode": added
+    PID and log messages of resolver sub-processes.
+  - Fixed host name lookups when using IDENT user lookups.
+  - "make clean" and "make maintainer-clean" remove more files now.
+
+  ngIRCd 0.8.0-pre1 (2004-05-07)
+  - Two new configuration options: "ChrootDir" and "MotdPhrase", thanks to
+    Benjamin Pineau <ben@zouh.org>. Now you can force the daemon to change
+    its root and working directory to something "safe". MotdPhrase is used
+    to define an "MOTD string" instead of a whole file, useful if the
+    "real" MOTD file would be outside the "jail".
+  - INVITE- and BAN-lists become synchronized between IRC+ servers when
+    establishing new connections, if the peer supports this as well.
+  - Reorganized autogen.sh and configure scripts.
+  - Fixed a wrong assert() which could cause the daemon to exit spuriously
+    when closing down connections.
+  - Better logging of decompression errors returned by zlib.
+  - Servers other than the destination server didn't clean up the invite
+    list of an "invite-only" channel properly when an INVITE'd user joined.
+  - Changed the reply of the MODE command to match the syntax of the
+    original ircd exactly: the unnecessary but missing ":" before the last
+    parameter has been added.
+  - Fixed TRACE: don't output "Serv" lines for ourself; display more info.
+  - Results of the resolver (hostnames and IDENT names) are discarded after
+    the client is successfully registered with the server.
+  - Better logging while establishing and shutting down connections.
+  - The type of service (TOS) of all sockets is set to "interactive" now.
+  - Added short command line option "-t" as alternative to "--configtest".
+  - Added optional support for "IDENT" lookups on incoming connections. You
+    have to enable this function with the ./configure switch "--with-ident".
+    The default is not to do IDENT lookups.
+
+ngIRCd 0.7.7 (2004-02-05)
+
+  - The info text ("real name") of users is set to "-" if none has been
+    specified using the USER command (e. g. "USER user * * :"). Reason:
+    the original ircd doesn't like empty ones and would KILL such users.
+  - Fixed (optional) TCP Wrapper test which was broken and could result in
+    false results. Thanks to Fuminori Tanizaki <tany@mcnet.ad.jp>!
+  - Removed "USE_" prefixes of configuration #defines.
+
+ngIRCd 0.7.6 (2003-12-05)
+
+  - Fixed abort() ("server crash") when INVITE'ing users to nonexistent
+    channels. Bug found by <hiddenx@wp.pl>.
+  - Extended version numbering of CVS versions (added date).
+  - Enhanced/fixed doc/Protocol.txt;
+
+ngIRCd 0.7.5 (2003-11-07)
+
+  - Fixed ban behavior: users which are banned from a channel can't no
+    longer send PRIVMSG's to this channel (fixes Bug #47).
+  - Fixed and enhanced the "penalty handling" of the server: commands that
+    require more resources block the client for a short time.
+  - Changed the internal time resolution to one second.
+  - New configuration variable "MaxConnectionsIP" to limit the number of
+    simultaneous connections from a single IP that the server will accept.
+    This configuration options lowers the risk of denial of service attacks
+    (DoS), the default is 5 connections per client IP.
+  - Fixed build problems under Mac OS X 10.3.
+  - Use "-pipe" when compiling with gcc, speeds things up a little :-)
+  - Added new configuration variable "Listen" to bind all listening
+    sockets of the server to a single IP address.
+  - Suppress misleading error message of diff during make run.
+  - Enhanced test-suite and made it work on GNU/Hurd.
+  - Fixed minor typo in debug output :-)
+
+ngIRCd 0.7.1 (2003-07-18)
+
+  - Included files to build Debian packages (located in "debian/").
+  - Updated config.guess and config.sub to newer upstream versions.
+  - NJOIN propagates user channel modes correctly again ... Upsa.
+  - Made Makefile more compatible with "make -j<n>".
+  - Added support for GNU/Hurd.
+  - Fixed a compiler warning related to an unnecessary assert().
+  - Enhanced VERSION command when using debug versions.
+
+ngIRCd 0.7.0 (2003-05-01)
+
+  - "ServerName" is checked better now: a dot (".") is required.
+  - The KILL command verifies and logs more parameters.
+
+  ngIRCd 0.7.0-pre2 (2003-04-27)
+  - CVS build system fixes (made autogen.sh more portable).
+  - Fixed compilation and test-suite on Solaris (tested with 2.6).
+  - New documentation file "doc/Platforms.txt" describing the status of
+    ngIRCd on the various tested platforms.
+  - Test for broken GCC on Mac OS X and disable "-pedantic" in this case.
+  - Disable "-ansi" on Cygwin: system headers are incompatible.
+  - The server tried to connect to other servers only once when DNS or
+    socket failures occurred.
+  - Fixed --configtest: There is no variable "ServerPwd", it's "Password".
+
+  ngIRCd 0.7.0-pre1 (2003-04-22)
+  - New signal handler (more secure, actions are executed outside).
+  - GCC: the compiler is now called with more warning options enabled.
+  - Replaced a lot of str[n]cpy(), str[n]cat() and sprintf() calls with the
+    more secure functions strlcpy(), strlcat() and snprintf(). On systems
+    that don't support strlcpy() and strlcat(), these functions are included
+    in the libngportab now (with prototypes in portab.h).
+  - If the server can't close a socket, it panics now. This is an error that
+    can't occur during normal operation so there is something broken.
+  - The order of log messages during disconnects is more "natural" now ;-)
+  - Cleaned up handling of server configuration structures: modifying and
+    removing servers during runtime works more reliable now.
+  - Compression code from "conn.[ch]" is now found in new "conn-zip.[ch]"
+  - Moved some connection functions from "conn.[ch]" to "conn-func.[ch]".
+  - New command CONNECT to enable and add server links. The syntax is not
+    RFC-compatible: use "CONNECT <name> <port>" to enable and connect an
+    configured server and "CONNECT <name> <port> <host> <mypwd> <peerpwd>"
+    to add a new server (ngIRCd tries to connect new servers only once!).
+  - Added DISCONNECT command ("DISCONNECT <name>") to disable servers.
+  - Restructured the documentation: Now the main language is English. The
+    german documentation has been removed (until there is a maintainer).
+  - Enhanced killing of users caused by a nickname collision.
+  - Better error detection for status code ("numerics") forwarding.
+  - Moved tool functions to own library: "libngtool".
+  - New command TRACE (you can trace only servers at the moment).
+  - New command HELP that lists all understood commands.
+  - There should no longer remain "unknown connections" (see e.g. LUSERS)
+    if an outgoing server link can't be established.
+  - Added AC_PREREQ(2.50) to configure.in for better autoconf compatibility.
+  - Conn_Close() now handles recursive calls for the same link correctly.
+  - ngIRCd can register itself with Rendezvous: to enable support pass the
+    new switch "--with-rendezvous" to configure.
+  - Added support for TCP Wrappers library: pass "--with-tcp-wrappers" to
+    configure to enable it.
+  - Changed some configure options to use "--with"/"--without" as prefix
+    instead of "--enable"/"--disable": "--without-syslog", "--without-zlib",
+    "--with-tcp-wrappers", and "--with-rendezvous".
+  - Better error reporting to clients on connect.
+  - Enhanced manual pages ngircd(8) and ngircd.conf(5).
+  - Documentation is now installed in $(datadir)/doc/ngircd.
+  - Enhanced hanling of NJOIN in case of nick collisions.
+
+ngIRCd 0.6.1, 2003-01-21
+
+  - Fixed KILL: you can't crash the server by killing yourself any more,
+    ngIRCd no longer sends a QUIT to other servers after the KILL, and you
+    can kill only valid users now.
+  - The server no longer forwards commands to ordinary users, instead it
+    answers with the correct error message ("no such server") now.
+  - WHOIS commands weren't always forwarded as requested.
+  - The server sets a correct default AWAY message now when propagating
+    between servers (bug introduced in 0.6.0).
+  - Fixed up and enhanced CHANINFO command: channel keys and user limits
+    are synchronized between servers now, too.
+  - MODE returns the key and user limit for channel members correctly now.
+  - Non-members of a channel could crash the server when trying to change
+    its modes or modes of its members.
+  - The server didn't validate weather a target user is a valid channel
+    member when changing his channel user modes which could crash ngIRCd.
+
+
+Older changes (sorry, only available in german language):
+
+ngIRCd 0.6.0, 2002-12-24
+
+  ngIRCd 0.6.0-pre2, 2002-12-23
+  - neuer Numeric 005 ("Features") beim Connect.
+  - LUSERS erweitert: nun wird die maximale Anzahl der lokalen und globalen
+    Clients, die dem Server bzw. im Netzwerk seit dem letzten (Re-)Start
+    dem Server gleichzeitig bekannt waren, angezeigt.
+
+  ngIRCd 0.6.0-pre1, 2002-12-18
+  - beim Schliessen einer Verbindung zeigt der Server nun vor dem ERROR
+    noch eine Statistik ueber die empfangene und gesendete Datenmenge an.
+  - der Server wartet bei einer eingehenden Verbindung nun laenger auf den
+    Resolver (4 Sekunden), wenn das Ergebnis eintrifft setzt er aber den
+    Login sofort fort (bisher wurde immer mind. 1 Sekunde gewartet).
+  - Connection-Strukturen werden nun "pool-weise" verwaltet; der Pool wird
+    bei Bedarf bis zu einem konfigurierten Limit vergroessert.
+  - Mit der neuen Konfigurationsvariable "MaxConnections" (Sektion "Global")
+    kann die maximale Anzahl gleichzeitiger Verbindungen begrenzt werden.
+    Der Default ist -1, "unlimitiert".
+  - der Server erkennt nun, ob bereits eine eingehende Verbindung von einem
+    Peer-Server besteht und versucht dann nicht mehr, selber eine eigene
+    ausgehende Verbindung zu diesem auufzubauen. Dadurch kann nun auf beiden
+    Servern in der Konfiguration ein Port fuer den Connect konfiguriert
+    werden (beide Server versuchen sich dann gegenseitig zu connectieren).
+  - Test-Suite und Dokumentation an A/UX angepasst.
+  - unter HP-UX definiert das configure-Script nun _XOPEN_SOURCE_EXTENDED.
+  - Server identifizieren sich nun mit asyncronen Passwoertern, d.h. das
+    Passwort, welches A an B schickt, kann ein anderes sein als das, welches
+    B als Antwort an A sendet. In der Konfig.-Datei, Abschnitt "Server",
+    wurde "Password" dazu durch "MyPassword" und "PeerPassword" ersetzt.
+  - Der Server kann nun zur Laufzeit die Konfiguration neu einlesen: dies
+    macht er nach dem Befehl REHASH oder wenn ein HUP-Signal empfangen wird.
+  - Channel-Mode "P" ("persistent") kann nur noch von IRC-Operatoren gesetzt
+    werden. Grund: User koennen den Server sonst leicht "Channel-Flooden".
+  - MOTD kann nun an andere Server geforwarded werden.
+  - IRC-Befehl "TIME" implementiert.
+  - Server-Server-Links koennen nun komprimiert werden, dazu wird die zlib
+    (www.zlib.org) benoetigt. Unterstuetzt die Gegenseite die Komprimierung
+    nicht, wird automatisch unkomprimiert kommuniziert. Das Verfahren ist
+    kompatibel mit dem Original-ircd 2.10.3, d.h. beide Server koennen
+    miteinander ueber komprimiert Links kommunizieren.
+  - Handling der Schreibpuffer umgestellt: Server sollte schneller arbeiten.
+  - Prefix-Fehler werden besser protokolliert (mit verursachendem Befehl).
+  - SQUIT wird nicht mehr doppelt an andere Server weitergeleitet.
+  - Der Server versucht nun vor dem Schliessen einer Verbindung Daten, die
+    noch im Schreibpuffer stehen, zu senden.
+  - Source in weiteres Modul "irc-info" aufgespalten.
+  - Konfigurationsvariablen werden besser validiert: Laengen, Zahlen, ...
+  - neuen Befehl STATS begonnen: bisher unterstuetzt wird "l" und "m".
+  - bei ISON und USERHOST fehlte im Ergebnis-String der korrekte Absender.
+  - IRC Operatoren koennen nun mit KILL User toeten. Achtung: ein Grund muss
+    zwingend als zweiter Parameter angegeben werden!
+  - neue Konfigurations-Variable "MaxJoins": Hiermit kann die maximale Zahl
+    der Channels, in denen ein User Mitglied sein kann, begrent werden.
+  - neuer, deutlich flexiblerer Parser fuer den MODE Befehl.
+  - neue Channel-Modes l (User-Limit) und k (Channel-Key) implementiert.
+
+ngIRCd 0.5.4, 24.11.2002
+
+  - Fehler-Handling von connect() gefixed: der Server kann sich nun auch   
+    unter A/UX wieder zu anderen verbinden.
+  - in den Konfigurationsvariablen ServerUID und ServerGID kann nun nicht
+    nur die numerische ID, sondern auch der Name des Users bzw. der Gruppe
+    verwendet werden. Beim Start des Daemons wird nun beides angezeigt.
+  - Besseres Logging von Prefix-Fehlern.
+  - angenommene Sockets werden nun korrekt auf "non-blocking" konfiguriert,
+    beim Senden und Empfangen werden Blockierungen besser abgefangen.
+  - RPL_UMODEIS hat Code 221, nicht 211 ... *argl*
+  - select() in Try_Write() hat falschen (keinen!) Timeout verwendet;
+    die "Zeit-Aufloesung" des Servers sind zudem nun 2 Sekunden (TIME_RES).
+    Insgesamt sollte die Reaktionszeit des Server nun besser sein.
+
+ngIRCd 0.5.3, 08.11.2002
+
+  - NOTICE liefert nun wirklich nie mehr einen Fehler, auch dann nicht,
+    wenn der sendende Client noch gar nicht registriert ist.
+  - ein "schneller Server-Reconnect" wird nur noch dann versucht, wenn die
+    Verbindung zuvor ordentlich (="lange genug") in Ordnung war; somit also
+    nicht meht, wenn der Peer-Server gleich beim Connect ein ERROR liefert.
+    Das vermeidet "Connect-Orgien".
+  - einige Datentypen aufgeraumt: z.B. sind viele INT32s nun LONGs. Das ist
+    auf Platformen mit 8-Byte-Integern kompatibler.
+  - RPL_YOURHOST_MSG ist nun ircII- und RFC-kompatibel ;-)
+  - Segfault unter hoher Netzaktivitaet behoben: in Conn_Close() wird die
+    Connection-Struktur nun frueher als "ungueltig" markiert.
+
+ngIRCd 0.5.2, 04.10.2002
+
+  - Buffer Overflow in Read_Resolver_Result() behoben.
+  - Format-String-Bugs, die zum Abbruch des Servers fuehrten, behoben.
+  - Maximale Laenge eines IRC-Prefix wurde falsch berechnet.
+
+ngIRCd 0.5.1, 03.10.2002
+
+  - in RPL_YOURHOST_MSG wurde ein fehlerhafter Versionsstring geliefert.
+  - Test-Suite: start-server.sh, stop-server.sh und stress-server.sh koennen
+    nun "manuell" von der Kommandozeile gestartet werden, stress-server.sh
+    startet per Default nur noch 5 Sessions, eine andere Zahl kann auf der
+    Kommandozeile uebergeben werden (Syntax: "stress-server.sh <count>").
+  - In bestimmten Faellen hat der Server versucht auf einen bereits wieder
+    geschlossenen Socket Daten zu schreiben; das fuehrte zu einem Abbruch des
+    Servers durch ein assert(). Nun wird geprueft, ob der Socket noch ok ist.
+  - im "contrib"-Verzeichnis befindet sich nun eine RPM-Spec-Datei, aus den
+    .tar.gz's koennen nun mit "rpm -ta <archiv>" RPM's erzeugt werden. Danke
+    an Sean Reifschneider <jafo@tummy.com>!
+  - Syntax von RPL_MYINFO_MSG korrigiert: liefert nun vier Parameter.
+
+ngIRCd 0.5.0, 20.09.2002
+
+  - Dokumentation aktualisiert.
+  - Fehler bei Validierung von "AdminInfo2" behoben.
+  - Test der Flags fuer "ps" in der Testsuite verbessert, ist nun zu mehr
+    Plattformen kompatibler.

+I. Upgrade Information
+~~~~~~~~~~~~~~~~~~~~~~
+
+Differences to version 0.9.x
+
+- The option of the configure script to enable support for Zeroconf/Bonjour/
+  Rendezvous/WhateverItIsNamedToday has been renamed:
+    --with-rendezvous  ->  --with-zeroconf
+
+Differences to version 0.8.x
+
+- The maximum length of passwords has been raised to 20 characters (instead
+  of 8 characters). If your passwords are longer than 8 characters then they
+  are cut at an other position now.
+
+Differences to version 0.6.x
+
+- Some options of the configure script have been renamed:
+    --disable-syslog  ->  --without-syslog
+    --disable-zlib    ->  --without-zlib
+  Please call "./configure --help" to review the full list of options!
+
+Differences to version 0.5.x
+
+- Starting with version 0.6.0, other servers are identified using asynchronous
+  passwords: therefore the variable "Password" in [Server]-sections has been
+  replaced by "MyPassword" and "PeerPassword".
+
+- New configuration variables, section [Global]: MaxConnections, MaxJoins
+  (see example configuration file "doc/sample-ngircd.conf"!).
 
 
- +-----------------------------------------------------------------------+
- | Please note: English translations of some of the german documentation |
- | files can be found in the directory "doc/en" -- please have a look!   |
- +-----------------------------------------------------------------------+
+II. Standard Installation
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ngIRCd is developed for UNIX-based systems, which means that the installation
+on modern UNIX-like systems that are supported by GNU autoconf and GNU
+automake ("configure") should be no problem.
+
+The normal installation procedure after getting (and expanding) the source
+files (using a distribution archive or GIT) is as following:
+
+  1) ./autogen.sh	[only necessary when using GIT]
+  2) ./configure
+  3) make
+  4) make install
+
+(Please see details below!)
+
+Now the newly compiled executable "ngircd" is installed in its standard
+location, /usr/local/sbin/.
+
+The next step is to configure and afterwards starting the daemon. Please
+have a look at the ngircd(8) and ngircd.conf(5) manual pages for details
+and all possible options.
+
+If no previous version of the configuration file exists (the standard name
+is /usr/local/etc/ngircd.conf), a sample configuration file containing all
+possible options will be installed there. You'll find its template in the
+doc/ directory: sample-ngircd.conf.
 
 
-I. Standard-Installation
+1): "autogen.sh"
+
+The first step, autogen.sh, is only necessary if the configure-script isn't
+already generated. This never happens in official ("stable") releases in
+tar.gz-archives, but when using GIT.
+
+This step is therefore only interesting for developers.
+
+autogen.sh produces the Makefile.in's, which are necessary for the configure
+script itself, and some more files for make. To run autogen.sh you'll need
+GNU autoconf and GNU automake (use recent versions! autoconf 2.53 and
+automake 1.6.1 are known to work).
+
+Again: "end users" do not need this step!
+
+
+2): "./configure"
+
+The configure-script is used to detect local system dependencies.
+
+In the perfect case, configure should recognise all needed libraries, header
+files and so on. If this shouldn't work, "./configure --help" shows all
+possible options.
+
+In addition, you can pass some command line options to "configure" to enable
+and/or disable some features of ngIRCd. All these options are shown using
+"./configure --help", too.
+
+Compiling a static binary will avoid you the hassle of feeding a chroot dir
+(if you want use the chroot feature). Just do something like:
+  CFLAGS=-static ./configure [--your-options ...]
+Then you can use a void directory as ChrootDir (like OpenSSH's /var/empty).
+
+
+3): "make"
+
+The make command uses the Makefiles produced by configure and compiles the
+ngIRCd daemon.
+
+
+4): "make install"
+
+Use "make install" to install the server and a sample configuration file on
+the local system. Normally, root privileges are necessary to complete this
+step. If there is already an older configuration file present, it won't be
+overwritten.
+
+This files will be installed by default:
+
+- /usr/local/sbin/ngircd: executable server
+- /usr/local/etc/ngircd.conf: sample configuration (if not already present)
+- /usr/local/share/doc/ngircd/: documentation
+
+
+III. Additional features
 ~~~~~~~~~~~~~~~~~~~~~~~~
 
-ngIRCd ist fuer UNIXoide-Systeme konzipiert worden, das bedeutet, dass die
-Installation auf einem modernen UNIX-aehnlichen System kein Problem dar-
-stellen sollte. Das System muss nur von GNU automake und GNU autoconf
-("configure") unterstuetzt werden.
+The following optional features can be compiled into the daemon by passing
+options to the "configure" script. Most options can handle a <path> argument
+which will be used to search for the required libraries and header files in
+the given paths ("<path>/lib/...", "<path>/include/...") in addition to the
+standard locations.
 
-Die Standard-Installation sieht so aus:
+* Syslog Logging (autodetected by default): 
+  --with-syslog[=<path>] / --without-syslog
 
-   1) tar xzf ngircd-<Version>.tar.gz
-   2) cd ngircd-<Version>
-   3) ./autogen.sh	[nur erforderlich, wenn ueber CVS bezogen]
-   4) ./configure
-   5) make
-   6) make install
+  Enable (disable) support for logging to "syslog", which should be
+  available on most modern UNIX-like operating systems by default.
+
+* ZLib Compression (autodetected by default):
+  --with-zlib[=<path>] / --without-zlib
+
+  Enable (disable) support for compressed server-server links.
+  The Z compression library ("libz") is required for this option.
+  
+* IO Backend (autodetected by default):
+  --with-select[=<path>] / --without-select
+  --with-poll[=<path>] / --without-poll
+  --with-devpoll[=<path>] / --without-devpoll
+  --with-epoll[=<path>] / --without-epoll
+  --with-kqueue[=<path>] / --without-kqueue  
+
+  ngIRCd can use different IO "backends": the "old school" select() and poll()
+  API which should be supported by most UNIX-like operating systems, or the
+  more efficient and flexible epoll() (Linux >=2.6), kqueue() (BSD) and
+  /dev/poll APIs.
+  By default the IO backend is autodetected, but you can use "--without-xxx"
+  to disable a more enhanced API.
+  When using the epoll() API, support for select() is compiled in as well by
+  default to enable the binary to run on older Linux kernels (<2.6), too.
+
+* IDENT-Support:
+  --with-ident[=<path>]
+
+  Include support for IDENT ("AUTH") lookups. The "ident" library is
+  required for this option.
+
+* ZeroConf Support:
+  --with-zeroconf[=<path>] 
+
+  Compile ngIRCd with support for ZeroConf multicast DNS service registration.
+  Either the Apple ZeroConf implementation (e. g. Mac OS X) or the Howl
+  library is required. Which one is available is autodetected.
+
+* TCP-Wrappers:
+  --with-tcp-wrappers[=<path>] 
+
+  Include support for Wietse Venemas "TCP Wrappers" to limit client access
+  to the daemon, for example by using "/etc/hosts.{allow|deny}".
+  The "libwrap" is required for this option.
 
 
-zu 3): "autogen.sh"
+IV. Useful make-targets
+~~~~~~~~~~~~~~~~~~~~~~~
 
-Der erste Schritt, autogen.sh, ist nur notwendig, wenn das configure-Script
-noch nicht vorhanden ist. Dies ist nie bei offiziellen ("stabilen") Versionen
-in tar.gz-Archiven der Fall, jedoch immer, wenn der Source-Code ueber CVS
-bezogen wurde.
+The Makefile produced by the configure-script contains always these useful
+targets:
 
-Dieser Absatz ist also eigentlich ausschliesslich fuer Entwickler interessant.
+ - clean: delete every product from the compiler/linker
+   next step: -> make
 
-autogen.sh erzeugt die fuer das configure-Script notwendigen Makefile.in's
-sowie das configure-Script selber und weitere fuer den make-Lauf erforderliche
-Dateien. Dazu wird sowohl GNU automake als auch GNU autoconf (in aktuellen
-Versionen!) benoetigt.
+ - distclean: the above plus erase all generated Makefiles
+   next step: -> ./configure
 
-(nochmal: "Endanwender" mussen diesen Schritt i.d.R. nicht ausfuehren!)
+ - maintainer-clean: erase all automatic generated files
+   next step: -> ./autogen.sh
 
 
-zu 4): "./configure"
+V. Sample configuration file ngircd.conf
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-Mit dem configure-Script wird ngIRCd, wie GNU Software meistens, an das
-lokale System angepasst und die erforderlichen Makefile's erzeugt.
+In the sample configuration file, there are comments beginning with "#" OR
+";" -- this is only for the better understanding of the file.
 
-Im Optimalfall sollte configure alle benoetigten Libraries, Header etc. selber
-erkennen und entsprechend reagieren. Sollte dies einmal nicht der Fall sein,
-so zeigt "./configure --help" moegliche Optionen.
+The file is separated in four blocks: [Global], [Operator], [Server], and
+[Channel].
+
+In the [Global] section, there is the main configuration like the server
+name and the ports, on which the server should be listening. IRC operators
+of this server are defined in [Operator] blocks. [Server] is the section
+where server links are configured. And [Channel] blocks are used to
+configure pre-defined ("persistent") IRC channels.
+
+The meaning of the variables in the configuration file is explained in the 
+"doc/sample-ngircd.conf", which is used as sample configuration file in
+/usr/local/etc after running "make install" (if you don't already have one)
+and in the "ngircd.conf" manual page.
 
 
-zu 5): "make"
+VI. Command line options
+~~~~~~~~~~~~~~~~~~~~~~~~
 
-Der make-Befehl bearbeitet die vom configure-Script erzeugten Makefile's und
-uebersetzt den ngIRCd.
-
-
-zu 6): "make install"
-
-Mit "make install" wird der Server und ggf. eine Beispiels-Konfiguration
-im System installiert; hierzu sind in der Regel root-Rechte erforderlich.
-Eine bereits vorhandene Konfigurationsdatei wird nie ueberschrieben.
-
-Folgende Dateien werden installiert:
-
-- /usr/local/sbin/ngircd: ausfuehrbarer Server
-- /usr/local/etc/ngircd.conf: Beispiel-Konfiguration, wenn nicht vorhanden
-
-
-II. Nuetzliche make-Targets
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Die vom configure-Script erzeugten Makefile's enthalten immer die folgenden
-nuetzlichen Targets:
-
- - clean: alle Erzeugnisse des Compilers/Linkers loeschen.
-   Naechster Schritt: -> make
-
- - distclean: zusaetzliche alle Makefile's loeschen.
-   Naechster Schritt: -> ./configure
-
- - maintainer-clean: alle automat. erzeugten Dateien loeschen.
-   Naechster Schritt: -> ./autogen.sh
-
-
-
-III. Konfigurationsdatei ngircd.conf
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In der Konfigurationsdatei werden Kommentare durch "#" oder durch ";"
-eingeleitet. Dieses dient nur der besseren Lesbarkeit.
-
-Die Datei ist in drei Abschnitte unterteilt: [Global], [Operator] und
-[Server]. Im [Global]-Teil werden die grundlegenden Einstellungen vor-
-genommen, z.B. der Server-Name und die Ports, auf denen er Verbindungen
-annehmen soll. In [Operator]-Abschnitten werden Server-Operatoren fest-
-gelegt und unter [Server] werden die Einstellungen fuer die Verbindung
-mit anderen Servern konfiguriert.
-
-Die Bedeutung der einzelnen Variablen ist in der Beispiel-Konfiguration
-"doc/sample-ngircd.conf" erklaert, die bei "make install" auch als
-"ngircd.conf" in /usr/local/etc installiert wird, wenn dort noch keine
-Konfigurationsdatei vorhanden ist.
-
-
-IV. Kommandozeilen-Optionen
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Folgende Parameter koennen dem ngIRCd u.a. uebergeben werden:
+These parameters could be passed to the ngIRCd:
 
 -f, --config <file>
-	Der Daemon wird angewiesen, statt der Standard-Konfigurationsdatei
-	/usr/local/etc/ngircd.conf die Datei <file> einzulesen.
+	The daemon uses the file <file> as configuration file rather than
+	the standard configuration /usr/local/etc/ngircd.conf.
 
 -n, --nodaemon
-	ngIRCd soll im Fordergrund laufen; alle Meldungen werden zusaetzlich
-	zum Syslog auch auf der Konsole ausgegeben.
+	ngIRCd should be running as a foreground process.
 
 -p, --passive
-	Verbindungen zu anderen Servern (wie in der Konfigurationsdatei in
-	[Server]-Abschnitten definiert) werden nicht automatisch hergestellt.
+	Server-links won't be automatically established.
 
---configtest
-	Die Konfigurationsdatei wird eingelesen, ueberprueft und so aus-
-	gegeben, wie sie vom ngIRCd interpretiert wurde. Danach beendet
-	sich der Server wieder.
+-t, --configtest
+	Reads, validates and dumps the configuration file as interpreted
+	by the server. Then exits.
 
-Mit dem Parameter "--help" werden alle unterstuetzten Parameter angezeigt,
-mit "--version" die Versionsnummer. Bei beiden Parametern beendet sich der
-Server nach der Ausgabe wieder.
-
-
--- 
-$Id: INSTALL,v 1.8 2002/09/16 11:03:05 alex Exp $
+Use "--help" to see a short help text describing all available parameters
+the server understands, with "--version" the ngIRCd shows its version
+number. In both cases the server exits after the output.

-ngIRCd CVS-HEAD
+ngIRCd 0.12.1 (2008-07-09)
+
+  - Add option aliases -V (for --version) and -h (for --help).
+  - Make Listen parameter a comma-seperated list of addresses. This also
+    obsoletes ListenIPv4 and ListenIPv6 options. If Listen is unset, it
+    is treated as Listen="::,0.0.0.0".
+    Note: ListenIPv4 and ListenIPv6 options are still recognized,
+    but ngircd will print a warning if they are used in the config file.
+
+ngIRCd 0.12.0 (2008-05-13)
+
+  ngIRCd 0.12.0-pre2 (2008-04-29)
+  - IPv6: Add config options to disabe ipv4/ipv6 support.
+
+  ngIRCd 0.12.0-pre1 (2008-04-20)
+  - Add IPv6 support.
+  - Install a LaunchDaemon script to start/stop ngIRCd on Mac OS X.
+  - Implemented IRC commands INFO, SUMMON (dummy), and USERS (dummy) and
+    enhanced test suite to check these commands. (Dana Dahlstrom)
+  - IRC_WHO now supports search patterns and will test this against user
+    nickname/servername/hostname, etc. as required by RFC 2812, Section 3.6.1.
+    (reported by Dana Dahlstrom)
+  - Implement RFC 2812 handling of "0" argument to 'JOIN': must be treated
+    as if the user had sent PART commands for all channels the user is a
+    member of. (Dana Dahlstrom)
+  - Allow NOTICEs to be sent to a channel. (Fabian Schlager)
+
+ngIRCd 0.11.0 (2008-01-15)
+
+  - Add support for /STAT u (server uptime) command.
+  - New [Server] configuration Option "Bind" allows to specify
+    the source ip adress to use when connecting to remote server.
+  - New configuration option "MaxNickLength" to specify the allowed maximum
+    length of user nick names. Note: must be unique in an IRC network!
+  - Numeric 317: implemented "signon time" (displayed in WHOIS result).
+  - Added new server configuration option "Passive" for "Server" blocks to
+    disable automatic outgoing connections (similar to -p option to ngircd,
+    but only for the specified server). (Tassilo Schweyer)
+  - Added support for the WALLOPS command. Usage is restricted to IRC
+    operators.
+
+ngIRCd 0.10.2 (2007-06-08)
+
+  - Predefined channel configuration now allows specification of channel key
+    (mode k) and maximum user count (mode l): variables "Key" and "MaxUsers".
+  - When using the epoll() IO interface, compile in the select() interface as
+    well and fall back to it when epoll() isn't available on runtime.
+  - Added support for IO APIs "poll()" and "/dev/poll".
+
+ngIRCd 0.10.1 (2006-12-17)
+
+  - Allow PASS syntax defined in RFC 1459 for server links, too.
+  - New configuration option "PredefChannelsOnly": if set, clients can only
+    join predefined channels.
+
+ngIRCd 0.10.0 (2006-10-01)
+
+  ngIRCd 0.10.0-pre1 (2006-08-02)
+  - Enhanced DIE to accept a single parameter ("comment text") which is sent
+    to all locally connected clients before the server goes down.
+  - JOIN now supports more than one channel key at a time.
+  - Implemented numeric "333": Time and user name who set a channel topic.
+  - Channel topics are no longer limited to 127 characters: now the only limit
+    is the maximum length of an IRC command, i. e. 512 bytes (in practice, this
+    limits the topic to about 490 characters due to protocol overhead).
+  - Reverse DNS lookup code now checks the result by doing an additional
+    lookup to prevent spoofing.
+  - Added new IO layer which (optionally) supports epoll() and kqueue() in
+    addition to the select() interface.
+
+ngIRCd 0.9.0 (2005-07-24)
+
+  - Never run with root privileges but always switch the user ID.
+  - Make "netsplit" messages RFC compliant.
+  - Implemented the IRC function "WHOWAS".
+  - New configuration option "OperServerMode" to enable a workaround needed
+    when running an network with ircd2 servers and "OperCanUseMode" enabled
+    to prevent the ircd2 daemon to drop mode changes of IRC operators.
+    Patch by Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+  - Implemented support for "secret channels" (channel mode "s").
+  - New configuration option "Mask" for [Operator] sections to limit OPER
+    commands to users with a specific IRC mask. Patch from Florian Westphal.
+  - New configuration variable "PidFile", section "[Global]": if defined,
+    the server writes its process ID (PID) to this file. Default: off.
+    Idea of Florian Westphal, <westphal@foo.fh-furtwangen.de>.
+  - Added support for the Howl (http://www.porchdogsoft.com/products/howl/)
+    Rendezvous API, in addition to the API of Apple (Mac OS X). The available
+    API will be autodetected when you call "./configure --with-rendezvous".
+
+ngIRCd 0.8.0 (2004-06-26)
+
+  - Two new configuration options: "ChrootDir" and "MotdPhrase", thanks to
+    Benjamin Pineau <ben@zouh.org>. Now you can force the daemon to change
+    its root and working directory to something "safe". MotdPhrase is used
+    to define an "MOTD string" instead of a whole file, useful if the
+    "real" MOTD file would be outside the "jail".
+  - INVITE- and BAN-lists become synchronized between IRC+ servers when
+    establishing new connections, if the peer supports this as well.
+  - The type of service (TOS) of all sockets is set to "interactive" now.
+  - Added short command line option "-t" as alternative to "--configtest".
+  - Added optional support for "IDENT" lookups on incoming connections. You
+    have to enable this function with the ./configure switch "--with-ident".
+    The default is not to do IDENT lookups.
+
+ngIRCd 0.7.5 (2003-07-11)
+
+  - New configuration variable "MaxConnectionsIP" to limit the number of
+    simultaneous connections from a single IP that the server will accept.
+    This configuration options lowers the risk of denial of service attacks
+    (DoS), the default is 5 connections per client IP.
+  - Added new configuration variable "Listen" to bind all listening
+    sockets of the server to a single IP address.
+       
+ngIRCd 0.7.1 (2003-07-18)
+
+  - Added support for GNU/Hurd.
+
+ngIRCd 0.7.0 (2003-05-01)
+
+  - New command CONNECT to enable and add server links. The syntax is not
+    RFC-compatible: use "CONNECT <name> <port>" to enable and connect an
+    configured server and "CONNECT <name> <port> <host> <mypwd> <peerpwd>"
+    to add a new server (ngIRCd tries to connect new servers only once!).
+  - Added DISCONNECT command ("DISCONNECT <name>") to disable servers.
+  - New command TRACE (you can trace only servers at the moment).
+  - New command HELP that lists all understood commands.
+  - ngIRCd can register itself with Rendezvous: to enable support pass the
+    new switch "--with-rendezvous" to configure.
+  - Added support for TCP Wrappers library: pass "--with-tcp-wrappers" to
+    configure to enable it.
+  - Changed some configure options to use "--with"/"--without" as prefix
+    instead of "--enable"/"--disable": "--without-syslog", "--without-zlib",
+    "--with-tcp-wrappers", and "--with-rendezvous".
+  - Enhanced manual pages ngircd(8) and ngircd.conf(5).
+  - Documentation is now installed in $(datadir)/doc/ngircd.
+
+
+Older news (sorry, only available in german language):
+
+ngIRCd 0.6.0, 2002-12-24
+
+  - beim Schliessen einer Verbindung zeigt der Server nun vor dem ERROR
+    noch eine Statistik ueber die empfangene und gesendete Datenmenge an.
+  - Connection-Strukturen werden nun "pool-weise" verwaltet; der Pool wird
+    bei Bedarf bis zu einem konfigurierten Limit vergroessert.
+  - Mit der neuen Konfigurationsvariable "MaxConnections" (Sekion "Global")
+    kann die maximale Anzahl gleichzeitiger Verbindungen begrenzt werden.
+    Der Default ist -1, "unlimitiert".
+  - der Server erkennt nun, ob bereits eine eingehende Verbindung von einem
+    Peer-Server besteht und versucht dann nicht mehr, selber eine eigene
+    ausgehende Verbindung zu diesem auufzubauen. Dadurch kann nun auf beiden
+    Servern in der Konfiguration ein Port fuer den Connect konfiguriert
+    werden (beide Server versuchen sich dann gegenseitig zu connectieren).
+  - Server identifizieren sich nun mit asyncronen Passwoertern, d.h. das
+    Passwort, welches A an B schickt, kann ein anderes sein als das, welches
+    B als Antwort an A sendet. In der Konfig.-Datei, Abschnitt "Server",
+    wurde "Password" dazu durch "MyPassword" und "PeerPassword" ersetzt.
+  - Der Server kann nun zur Laufzeit die Konfiguration neu einlesen: dies
+    macht er nach dem Befehl REHASH oder wenn ein HUP-Signal empfangen wird.
+  - Server-Server-Links koennen nun komprimiert werden, dazu wird die zlib
+    (www.zlib.org) benoetigt. Unterstuetzt die Gegenseite die Komprimierung
+    nicht, wird automatisch unkomprimiert kommuniziert. Das Verfahren ist
+    kompatibel mit dem Original-ircd 2.10.3, d.h. beide Server koennen
+    miteinander ueber komprimiert Links kommunizieren.
+  - neue Konfigurations-Variable "MaxJoins": Hiermit kann die maximale Zahl
+    der Channels, in denen ein User Mitglied sein kann, begrent werden.
+  - neue Channel-Modes l (User-Limit) und k (Channel-Key) implementiert.
+
+ngIRCd 0.5.0, 20.09.2002
 
-  - Manual-Pages ngircd.8 und ngircd.conf.5 begonnen.
   - AIX (3.2.5), HP-UX (10.20), IRIX (6.5), NetBSD (1.5.3/m68k) und Solaris
     (2.5.1, 2.6) gehoeren nun auch zu den unterstuetzten Platformen.
+  - Unter A/UX (und evtl. weiteren Systemen) kompiliert der ngIRCd nun mit
+    dem "nativen" (ggf. pre-ANSI) Compiler.
   - "persistente Channels" (Mode 'P') implementiert: diese koennen in der
     Konfigurationsdatei definiert werden (Sektion "Channel", vgl. Beispiel-
     Konfiguration "sample-ngircd.conf") und bleiben auch dann bestehen,
-    wenn kein User mehr im Channel ist. Zu Channel-Operatoren werden bisher
-    nur IRC-Operatoren, die den Channel betreten. Die persistenten Channels
-    werden durch das Flag "P" gelennzeichnet, welches normal durch Channel-
-    Op's gesetzt und geloescht werden kann.
-  - KICK implementiert (bisher kann nur ein User aus einem Channel geckicked
-    werden, Listen, wir im RFC vorgesehen, werden bisher nicht unterstuetzt).
-  - INVITE, den Channel-Mode "i" sowie Invite-Lists ueber den MODE-Befehl
-    (setzen, erfragen und loeschen) implementiert.
-  - Unter A/UX (und evtl. weiteren Systemen) kompiliert der ngIRCd nun mit
-    dem "nativen" (ggf. pre-ANSI) Compiler.
-  - LIST versteht nun Wildcards und kann an andere Server geforwarded werden.
+    wenn kein User mehr im Channel ist.
+  - neue IRC-Befehle: KICK, INVITE, ADMIN, CHANINFO; LIST wurde erweitert.
+    Mit dem neuen Befehl CHANINFO syncronisieren Server, die das IRC+-
+    Protokoll unterstuetzen, Channel-Modes und Topics. Fuer den ADMIN-Befehl
+    gibt es neue Konfigurationsoptionen (Sektion "Global"): "AdminInfo1",
+    "AdminInfo2" und "AdminEMail".
+  - Invite- und Ban-Lists implementiert.
   - neue Konfigurationsoption "OperCanUseMode" (Sektion "Global"):
     ist sie aktiv, koennen IRC-Operatoren immer Channel-Modes setzen.
-  - mit dem neuen Befehl CHANINFO syncronisieren Server, die das IRC+-
-    Protokoll unterstuetzen, Channel-Modes und Topics.
-  - Ban-Lists (setzen, erfragen und loeschen) implementiert.
-  - ADMIN-Befehl implementiert.
+  - "Test-Suite" begonnen: mit "make check" wird sie durchlaufen.

+I. Introduction
+~~~~~~~~~~~~~~~
 
+ngIRCd is an Open Source server for the Internet Relay Chat (IRC), which
+is developed and published under the terms of the GNU General Public
+Licence (URL: http://www.gnu.org/licenses/gpl.html). ngIRCd means "next
+generation IRC daemon", it's written from scratch and not deduced from the
+"grandfather of IRC daemons", the daemon of the IRCNet.
 
-I. Einfuehrung
-~~~~~~~~~~~~~~
-
-ngIRCd ist ein Open-Source-Server fuer den Internet Relay Chat (IRC), der
-unter der GNU General Public License (http://www.gnu.org/licenses/gpl.html)
-entwickelt wird. ngIRCd steht fuer "next generation IRC daemon", er ist von
-Grund auf neu geschrieben, also nicht wie die meisten anderen IRCd's vom
-Urvater, dem Daemon des IRCNet abgeleitet.
+Please see the INSTALL document for installation and upgrade information!
 
 
 II. Status
 ~~~~~~~~~~~
 
-Zur Zeit befindet sich der ngIRCd noch in Entwicklung, manche Features sind
-noch nicht implementiert, andere nur teilweise.
+It is not the goal of ngIRCd to implement all the nasty behaviours of the
+original ircd, but to implement most of the useful commands and semantics
+specified by the RFCs.
 
-Bisher (mehr oder wenig vollstaendig) implementierte IRC-Befehle:
+In the meantime ngIRCd should be quite feature complete and stable to be
+used in real IRC networks.
 
-ADMIN, AWAY, CHANINFO, CONNECT, DIE, ERROR, INVITE, ISON, JOIN, KICK, KILL,
-LINKS, LIST, LUSERS, MODE, MOTD, NAMES, NICK, NJOIN, NOTICE, OPER, PART,
-PASS, PING, PONG, PRIVMSG, QUIT, RESTART, SERVER, SQUIT, TOPIC, USERHOST,
-USER, VERSION, WHO, WHOIS.
+Implemented IRC-commands are:
+
+ADMIN, AWAY, CHANINFO, CONNECT, DIE, DISCONNECT, ERROR, HELP, INVITE, ISON,
+JOIN, KICK, KILL, LINKS, LIST, LUSERS, MODE, MOTD, NAMES, NICK, NJOIN, NOTICE,
+OPER, PART, PASS, PING, PONG, PRIVMSG, QUIT, REHASH, RESTART, SERVER, SQUIT,
+STATS, TIME, TOPIC, TRACE, USER, USERHOST, VERSION, WALLOPS, WHO, WHOIS,
+WHOWAS.

+# This script generates the ./configure script using GNU automake and
+# GNU autoconf. It tries to be smart in finding the correct/usable/available
+# installed versions of these tools on your system.
+#
+# The following strategy is used for each of aclocal, autoheader, automake,
+# and autoconf: first, "tool" (the regular name of the tool, e. g. "autoconf"
+# or "automake") is checked. If this fails, "tool<major><minor>" (for example
+# "automake16") and "tool-<major>.<minor>" (e. g. "autoconf-2.54") are tried
+# with <major> being 2 for tool of GNU autoconf and 1 for tools of automake;
+# <minor> is tried from 99 to 0. The first occurrence will be used.
+#
+# When you pass <configure-args> to autogen.sh it will call the generated
+# ./configure script on success and pass these parameters to it.
+#
+# You can tweak the behaviour using these environment variables:
+#
+# - ACLOCAL=<cmd>, AUTOHEADER=<cmd>, AUTOMAKE=<cmd>, AUTOCONF=<cmd>
+#   Name and optionally path to the particular tool.
+# - PREFIX=<path>
+#   Search the GNU autoconf and GNU automake tools in <path> first. If the
+#   generated ./configure script will be called, pass "--prefix=<path>" to it.
+# - EXIST=<tool>
+#   Use <tool> to test for aclocal, autoheader etc. pp. ...
+#   When not specified, either "type" or "which" is used.
+# - VERBOSE=1
+#   Output the detected names of the GNU automake and GNU autoconf tools.
+# - GO=1
+#   Call ./configure even if no arguments have been passed to autogen.sh.
+#
+# Examples:
+#
+# - ./autogen.sh
+#   Generates the ./configure script.
+# - GO=1 ./autogen.sh
+#   Generates the ./configure script and runs it as "./configure".
+# - VERBOSE=1 ./autogen.sh --with-ident
+#   Show tool names, generates the ./configure script, and runs it with

+ syslog logging and compressed server-links using zlib.
+ .
+ Advantages of ngIRCd:
+  - no problems with servers using changing/non-static IP addresses.
+  - small and lean configuration file.
+  - free, modern and open source C code.
+  - still under active development.
+ .
+ ngIRCd is compatible to the "original" ircd 2.10.3p3, so you can run

+%description
+ngIRCd is a free open source daemon for the Internet Relay Chat (IRC),
+developed under the GNU General Public License (GPL). It's written from
+scratch and is not based upon the original IRCd like many others.
+
+Advantages:
+ - no problems with servers using changing/non-static IP addresses.
+ - small and lean configuration file.
+ - free, modern and open source C code.
+ - still under active development.
+
+ngIRCd is compatible to the "original" ircd 2.10.3p3, so you can run
+mixed networks.

-
-
-Die Sourcen des ngIRCd werden mit dem "Concurrent Versions System" (CVS)
-verwaltet. Somit koennen ohne Probleme mehrere Leute gleichzeitig die Sourcen
-bearbeitet.
-
-
-I. Anonymer "Nur-Lesen"-Zugang
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Anonymer Zugriff auf die CVS-Repository von ngIRCd ist im "nur-lesen"-Modus
-moeglich. Dazu sind folgende Schritte noetig:
-
-Beim CVS-Server anmelden
-
- $ cvs -d:pserver:anonymous@arthur.ath.cx:/usr/local/CVS/ngircd login
-
-Als Benutzername wird "anonymous" mit einem leeren Passwort verwendet.
-Nun ein "Check-Out" der Quellcodes durchfuehren:
-
- $ cvs -d:pserver:anonymous@arthur.ath.cx:/usr/local/CVS/ngircd checkout ngircd
-
-Dadurch wird im aktuellen Verzeichnis der neue Ordner "ngircd" mit allen
-Quell-Dateien des ngIRCd erzeugt.
-
-Dieses ist der "Arbeitsordner", alle CVS-Befehle werden in Zukunft aus
-diesem Ordner bzw. einem Unterordner davon ausgefuehrt.
-
-Wichtig: wenn ngIRCd "frisch" aus dem CVS compiliert werden soll, so
-existiert das configure-Script noch nicht. Dieses muss zunaechst mit dem
-Script "autogen.sh" erzeugt werden. Letzteres setzt ein installiertes GNU
-automake und GNU autoconf voraus!
-
-CVS-Tree aktualisieren:
-
- $ cvs update
-
-Dieser Befehl aktualisiert alle Dateien im aktuellen Verzeichnis sowie allen
-Unterverzeichnissen.
-
- $ cvs update <filename>
-
-So kann eine einzelne Datei aktualisiert werden (auch dann, wenn sie lokal
-z.B. geloescht wurde -- praktisch, um eigene "Experimente" rueckgaengig zu
-machen ;-))
-
-
-III. Schreibzugriff
-~~~~~~~~~~~~~~~~~~~
-Wer Schreibzugriff auf die CVS-Repository wuenscht, der moege sich bitte
-mit Alex Barton, <alex@barton.de> in Verbindung setzen.

                     -- FAQ: Frequently Asked Questions --
 
 
-I. Allgemein
-~~~~~~~~~~~~
-Q: Kann der ngIRCd im Netz zusammen mit "normalen" Servern betrieben werden?
-A: Ja. ngIRCd ist zum Original kompatibel, getestet wird dies zur Zeit mit
-   der Version 2.10.3p3 des ircd.
+I. General
+~~~~~~~~~~
+Q: Is it possible to link the ngIRCd with non-ngIRCd servers?
+A: Yes. ngIRCd is compatible to the original ircd used by IRCNet. Actually
+   this is being tested with version 2.10.3p3.
 
-Q: Gibt es eine Homepage mit Informationen und Downloads?
-A: Ja. Die URL ist <http://arthur.ath.cx/~alex/ngircd/>.
+Q: Is there a homepage with further information and downloads?
+A: Yes. Please visit <http://ngircd.barton.de/>.
+
+Q: Why should I use ngIRCd instead of the original one?
+A: ngIRCd offers several benefits: no problems with dynamic IPs, easy to
+   configure, open source (GPL), under active development.
 
 
-II. Compilieren
+II. Compilation
 ~~~~~~~~~~~~~~~
-Q: Ich habe die Sourcen von ngIRCd ueber CVS installiert. Nun kann ich
-   ./configure nicht ausfuehren, da es nicht existiert!?
-A: Bei Builds direkt aus dem CVS-Tree muss das configure-Script zunaechst
-   durch GNU autoconf sowie die Makefile.in's durch GNU automake generiert
-   werden. Um dies zu vereinfachen existiert das Script "./autogen.sh".
-   GNU automake und GNU autoconf werden -- im Gegensatz zu Builds aus den
-   Sourcen eines .tar.gz-Archivs -- hierbei benoetigt!
+Q: I did a "CVS checkout" but can't execute ./configure because the script
+   is missing in the generated directory!?
+A: When using development versions via CVS, the configure script as well as
+   the Makefile.in templates must be generated using GNU automake and GNU
+   autoconf. To simplify this task run the ./autogen.sh script which will
+   execute the required tools for you; then continue with executing the
+   ./configure script as usual.
 
-Q: ./autogen.sh bricht mit der Meldung "autoheader: command not found" ab.
-A: GNU autoconf ist nicht installiert, wird jedoch bei Builds direkt aus
-   dem CVS-Tree benoetigt.
+Q: The ./autogen.sh script complains "aclocal: command not found".
+A: GNU automake is missing on your system but required for building CVS
+   versions of ngIRCd. Install GNU automake 1.6 or later and try again.
 
-Q: ./autogen.sh bricht mit der Meldung "autoconf: Undefined macros:
-   AC_FUNC_MALLOC" bzw. "AC_CONFIG_SRCDIR" ab.
-A: Auf dem System ist eine zu alte Version von GNU autoconf installiert.
-   Ein Update auf z.B. Version 2.52 loest dieses Problem (eine installiete
-   alte Version sollte ggf. zunaechst entfernt werden, bei RPM-Paketen z.B.
-   mit dem Befehl "rpm -e autoconf").
+Q: The ./autogen.sh script stops with "autoheader: command not found".
+A: GNU autoconf is missing on your system but required for building CVS
+   versions of ngIRCd. Install GNU autoconf 2.52 or later and try again.
+
+Q: The ./autogen.sh script fails and the message "automake: configure.in:
+   AM_INIT_AUTOMAKE must be used" is displayed.
+A: Most probably you are using version 1.5 of GNU automake which seems to be
+   incompatible to the build system of ngIRCd. Solution: upgrade to at least
+   version 1.6 of GNU automake.
+   (If you are using Debian 3.0 "Woody" you can try to downgrade to version
+   1.4 of GNU automake shipped with this distribution; it should work, too.)
 
 
-III. Bugs!?
-~~~~~~~~~~~
-Q: Gibt es eine Liste der bekannten Bugs bzw. Feature-Wuensche?
-A: Ja. Es existiert ein Bug-Tracking-System fuer den ngIRCd (Bugzilla):
-   URL: <http://arthur.ath.cx/bugzilla/ngircd/>. Dort koennen Bugs ge-
-   meldet und Feature-Wunsche kundgetan werden. Bekannte Bugs koennen in
-   der Datenbank gesucht und aufgelistet werden.
-   Einen Account zum Suchen und Melden von Bugs bzw. Feature-Wuenschen
-   kannst du dir dort selber anlegen.
+III. Runtime
+~~~~~~~~~~~~
 
-Q: Was mache ich, wenn ich einen Bug gefunden habe?
-A: Am besten traegst du ihn in das Bug-Tracking-System des ngIRCd ein:
-   URL: <http://arthur.ath.cx/bugzilla/ngircd/>
+Q: I cannot connect to remote peers when I use the chroot option, the
+   following is logged: "Can't resolve example.com: unknown error!".
+A: On Linux/glibc with chroot enabled you need to put some libraries inside
+   the chroot as well, notably libnss_dns; maybe others. Unfortunately, even
+   linking ngircd statically does not help this. The only known workaround
+   is to either disable chroot support or to link against dietlibc instead
+   of glibc. (tnx to Sebastian Siewior)
+
+
+IV. Bugs!?
+~~~~~~~~~~
+Q: Is there a list of known bugs and desired feature enhancements?
+A: Yes. Have a look at the bug tracking system (Bugzilla) for ngIRCd located
+   at <http://ngircd.barton.de/bugzilla/index.cgi>. There you can file bug
+   reports and feature requests as well as search the bug database.
+
+Q: What should I do if I found a bug?
+A: Please file a bug report at <http://ngircd.barton.de/bugzilla/index.cgi>!
+   The author of the particular component will be notified automagically :-)

+The source code of ngIRCd is maintained using git, the stupid content
+tracker.
+
+I. Getting the source code
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+To access the source tree anonymously, run:
+
+ $ git clone git://ngircd.barton.de/ngircd.git
+
+Thereby a new folder "ngircd" will be created containing all the individual
+source files.
+
+The newly created directory ("ngircd") is the "working directory", all
+git commands will be executed from within this directory in the future.
+
+Please note: When checking out a fresh copy of ngIRCd using git, the
+configure script doesn't exist; you have to run the autogen.sh shell script
+(which is included in the source tree) to generate it. This requires you to
+have GNU automake and GNU autoconf installed on your system.
+
+To update the git tree:
+
+ $ git pull
+
+This retrieves all changes and merges them into the current branch.
+
+II. Contributing
+~~~~~~~~~~~~~~~~
+
+Patches should be sent to the ngircd mailing list. List homepage:
+http://arthur.barton.de/mailman/listinfo/ngircd-ml
+
+If you do not want to send them to the list, you can also mail them
+to Alex Barton, <alex@barton.de>.
+
+
+III. Write Access
+~~~~~~~~~~~~~~~~~
+If you want to contribute a couple of patches and write access to the git
+repository would be handy, please contact Alex Barton, <alex@barton.de>.

-I. Kompatibilitaet
-~~~~~~~~~~~~~~~~~~
+I. Compatibility
+~~~~~~~~~~~~~~~~
 
-Der ngIRCd haelt sich an das IRC-Protokoll Version 2.10, wie es in den RFCs
-1459 und 2810-2813 beschrieben ist. Diese (und ggf. weitere fuer den ngIRCd
-relevante) RFCs sind in RFC.txt aufgefuehrt.
+The ngIRCd implements the Internet Relay Chat (IRC) protocol version 2.10
+as defined in RFC ("request for comment") 1459 and 2810-2813. These (and
+probably further relevant RFCs) are listed in doc/RFC.txt.
 
-Leider verhaelt sich aber schon der "Originalserver" nicht immer genau so,
-wie es in den RFCs beschrieben ist. Da der ngIRCd aber ein Ersatz fuer
-eben diesen Server sein soll, werden diese Abweichungen in der Regel vom
-ngIRCd emuliert um die Kompatibilitaet zu wahren.
+Unfortunately, even the "original" ircd doesn't follow these specifications
+in all details. But because the ngIRCd should be a fully compatible
+replacement for this server ("ircd") it tries to emulate these differences.
 
-Sollte dieses Verhalten nicht erwuenscht sein, so kann mit der configure-
-Option "--enable-strict-rfc" der ngIRCd so compiliert werden, dass er sich
-strikt an die entsprechenden RFCs haelt.
-
-ACHTUNG: an einem so compilierten Server koennen sich andere Server und
-Clients, die sich nicht genau an das Protokoll halten, u.U. nicht mehr
-anmelden oder alle Funktionen nutzen! In der Regel ist diese Option daher
-nicht erwuenscht.
+If you don't like this behavior please ./configure the ngIRCd using the
+"--enable-strict-rfc" command line option. But keep in mind: not all IRC
+clients are compatible with a server configured that way, some can't even
+connect at all! Therefore this option usually isn't desired for "normal
+server operation".
 
 
-II. Das IRC+-Protokoll
-~~~~~~~~~~~~~~~~~~~~~~
+II. The IRC+ Protocol
+~~~~~~~~~~~~~~~~~~~~~
 
-Der ngIRCd unterstuetzt als Erweiterung zum IRC-Protokoll wie es in den RFCs
-2810-2813 beschrieben ist, das IRC+-Protokoll. Dieses Protokoll ist dabei
-kompatibel zum IRC-Protokoll und wird nur verwendet, wenn der ngIRCd fest-
-stellt, dass ein connectierter Server ebenfalls dieses erweiterte Protokoll
-unterstuetzt.
+Starting with version 0.5.0, the ngIRCd extends the original IRC protocol
+as defined in RFC 2810-2813. This enhanced protocol is named "IRC+". It is
+backwards compatible to the "plain" IRC protocol and will only be used by
+the ngIRCd if it detects that the peer supports it as well.
 
-Die Protokoll- und Server-Erkennung wird mit dem "PASS"-Befehl durchgefuehrt
-(vgl. RFC 2813, Sektion 4.1.1):
+The "PASS" command is used to detect the protocol and peer versions see
+RFC 2813 (section 4.1.1) and below.
 
 
-II.1 neuen Server-Link registrieren
+II.1 Register new server link
 
-     Befehl: PASS
-  Parameter: <password> <version> <flags> [<options>]
-       Fuer: mit dieser Syntax nur Server
+     Command: PASS
+  Parameters: <password> <version> <flags> [<options>]
+     Used by: servers only (with these parameters)
 
-<password> enthaelt das Passwort fur den neu aufzubauenden Server-Link,
-so wie es in der Konfigurationsdatei definiert wurde.
+<password> is the password for this new server link as defined in the server
+configuration which is sent to the peer or received from it.
 
-<version> setzt sich aus zwei Teilen zusammen und ist mindestens 4, maximal
-14 Zeichen lang: die ersten vier Bytes enthalten die Versionsnummer des
-unterstuetzten IRC-Protokolls, wobei die ersten zwei Bytes die Major-, die
-letzten beiden die Minor-Revision angeben. Der String "0210" steht also
-fuer Protokollversion 2.10.
-Die folgenden (optionalen!) 10 Bytes enthalten eine von der jeweiligen
-Implementation abhaengige Versionsnummer. Server, die das IRC+-Protokoll
-unterstuetzen, liefern hier "-IRC+".
+<version> consists of two parts and is at least 4, at most 14 characters
+long: the first four bytes contain the IRC protocol version number, whereas
+the first two bytes represent the major version, the last two bytes the
+minor version (the string "0210" indicates version 2.10, e.g.).
 
-<flags> setzt sich ebenfalls aus zwei Bestandteilen zusammen und ist
-maximal 100 Bytes lang. Getrennt werden die beiden Teile mit dem Zeichen
-"|". Der erste Teil enthaelt den Namen der Implementation, der ngIRCd
-liefert hier z.B. "ngIRCd", der Originalserver "IRC". Anhand dieser "ID"
-kann zwischen Serverimplementationen unterschieden werden. Der zweite Teil
-(nach dem "|") ist implementationsabhaengig und wird nur ausgewertet,
-wenn die Gegenseite das IRC+-Protokoll unterstuetzt. In diesem Fall wird
-folgende Syntax erwartet: "<serverversion>[:<serverflags>]".
+The following optional(!) 10 bytes contain an implementation-dependent
+version number. Servers supporting the IRC+ protocol as defined in this
+document provide the string "-IRC+" here.
 
-<serverversion> ist hier eine ASCII-Klartext-Darstellung der Versionsnummer,
-<serverflags> zeigt die vom Server unterstuetzten Erweiterungen an (und
-kann die leere Menge sein).
+Example for <version>: "0210-IRC+".
 
-Mit dem optionalen Parameter <options> werden Server-Optionen uebermittelt,
-wie sie in RFC 2813, Sektion 4.1.1 definiert sind.
+<flags> consists of two parts separated with the character "|" and is at
+most 100 bytes long. The first part contains the name of the implementation
+(ngIRCd sets this to "ngircd", the original ircd to "IRC", e.g.). The second
+part is implementation-dependent and should only be parsed if the peer
+supports the IRC+ protocol as well. In this case the following syntax is
+used: "<serverversion>[:<serverflags>]".
 
-Folgende <serverflags> sind zur Zeit definiert:
+<serverversion> is an ASCII representation of the clear-text server version
+number, <serverflags> indicates the supported IRC+ protocol extensions (and
+may be empty!).
 
-- o: IRC-Operatoren duerfen auch dann Channel- und Channel-User-Modes
-     aendern, wenn sie kein Channel-Operator im betroffenen Channel sind.
+The following <serverflags> are defined at the moment:
 
-- C: der Server unterstuetzt den CHANINFO-Befehl.     
+- C: The server supports the CHANINFO command.
+
+- L: INVITE- and BAN-lists should be synchronized between servers: if the
+     peer understands this flag, it will send "MODE +I" and "MODE +b"
+     commands after the server link has been established.
+
+- H: The server supports the "enhanced server handshake", see section II.2
+     for a detailed description.
+
+- o: IRC operators are allowed to change channel- and channel-user-modes
+     even if they aren't channel-operator of the affected channel.
+
+- Z: Compressed server links are supported by the server.
+
+Example for a complete <flags> string: "ngircd|0.7.5:CZ".
+
+The optional parameter <options> is used to propagate server options as
+defined in RFC 2813, section 4.1.1.
 
 
-II.2 Channel-Modes, persistente Channel und Topic austauschen
+II.2 Enhanced Server Handshake
 
-     Befehl: CHANINFO
-  Parameter: <channel> +<mode> [<topic>]
-       Fuer: Server
+The "enhanced server handshake" is used when both servers support this IRC+
+extension, which is indicated by the 'H' flag in the <serverflags> sent with
+the PASS command, see section II.1.
 
-Mit CHANINFO Informiert ein Server den anderen ueber einen Channel: dessen
-Modes und dessen Topic. <topic> ist optional.
+It basically means, that after exchanging the PASS and SERVER commands the
+server is not registered in the network (as usual), but that IRC numerics
+are exchanged until the numeric 376 (ENDOFMOTD) is received. Afterwards the
+peer is registered in the network as with the regular IRC protocol.
 
-Existiert auf dem Server, der das CHANINFO empfaengt, der Channel bereits,
-so uebernimmt er die Werte jeweils nur dann, wenn er selber noch keine
-Modes bzw. kein Topic definiert hat. Ansonsten wird der jeweilige Parameter
-ignoriert.
+A server implementing the enhanced server handshake (and indicating this
+using 'H' in the <serverflags>) MUST ignore all unknown numerics to it
+silently.
 
-Existiert der Channel noch nicht, so wird er mit den entsprechenden Angaben
-erzeugt.
+In addition, such a server should at least send the numeric 005 (ISUPPORT)
+to its peer, containing the following information. Syntax: <key>=<value>,
+one token per IRC parameter. If the server has to send more than 12 token
+it must send separate ISUPPORT numerics (this is a limitation of the IRC
+protocol which allows at max 15 arguments per command).
+
+ - NICKLEN: Maximum nickname length. Default: 9.
+ - CASEMAPPING: Case mapping used for nick- and channel name comparing.
+   Default: "ascii", the chars [a-z] are lowercase of [A-Z].
+ - PREFIX: List of channel modes a person can get and the respective prefix
+   a channel or nickname will get in case the person has it. The order of the
+   modes goes from most powerful to least powerful. Default: "(ov)@+"
+ - CHANTYPES: Supported channel prefixes. Default: "#".
+ - CHANMODES: List of channel modes for 4 types, separated by comma (","):
+   Mode that adds or removes a nick or address to a list, mode that changes
+   a setting (both have always has a parameter), mode that changes a setting
+   and only has a parameter when set, and mode that changes a setting and
+   never has a parameter. For example "bI,k,l,imnPst".
+ - CHANLIMIT: Maximum number of channels allowed to join by channel prefix,
+   for example "#:10".
+
+Please see <http://www.irc.org/tech_docs/005.html> for details.
+
+The information exchanged using ISUPPORT can be used to detect configuration
+incompatibilities (different maximum nick name length, for example) and
+therefore to disconnect the peer prior to registering it in the network.
+
+
+II.3 Exchange channel-modes, topics, and persistent channels
+
+     Command: CHANINFO
+  Parameters: <channel> +<modes> <key> <limit> [<topic>]
+     Used by: servers only
+
+CHANINFO is used by servers to inform each other about a channel: its
+modes, channel key, user limits and its topic. <topic> is optional.
+
+If the channel already exists on the server receiving the CHANINFO command,
+it only adopts the <modes> (or the <topic>) if there are no modes (or topic)
+already set. It there are already values set the server ignores the
+corresponding parameter.
+
+If the channel doesn't exists at all it will be created.
+
+The parameter <key> must be ignored if a channel has no key (the parameter
+<modes> doesn't list the "k" channel mode). In this case <key> should
+contain "*" because the parameter <key> is required by the CHANINFO syntax
+and therefore can't be omitted. The parameter <limit> must be ignored when
+a channel has no user limit (the parameter <modes> doesn't list the "l"
+channel mode). In this case <limit> should be "0".

-Noch ein paar Hinweise, wenn es doch (noch) nicht klappt:
+Since version 0.2.2-pre Apple's A/UX belongs to the officially supported 
+platforms. It is not restricted in any way.
 
-  - auf dem System muss entweder ein install vorhanden sein, welches so
-    "broken" ist, dass configure das eigene Shell-Skript waehlt, oder eben
-    eines, welches funktioniert. Leider ist mindestens ein Binary im Um-
-    lauf, welches Probleme verursacht. Das Binary aus folgenden GNU
-    fileutils funktioniert hier aber z.B.:
-    ftp://arthur.ath.cx/pub/UNIX/AUX/Software/Tools/fileutils-4.0.tar.gz
+Since version 0.5.0 ngIRCd's source compiles with the native A/UX c 
+compiler. GNU C isn't a must-have anymore.
 
-  - das sich im Umlauf befindende vorcompilierte Binary der alten Bash sollte
-    unbedingt ausserhalb von /bin (z.B. unter /usr/local/bin) installiert
-    werden. Ansonsten waehlt es das configure-Script als Shell aus, leider
-    funktioniert das aber nicht.
-    Das config.status-Script sollte mit der ksh als Interpreter erstellt
-    worden sein (siehe erste Zeile davon!).
+The following software packages are needed:
+
+ - GNU sed
+   Source:

+
+   Warning: When installing GNU sed please make sure that A/UX doesn't
+   use the old one anymore which means set the $PATH or replace /bin/sed
+   at all.
+
+ - libUTIL.a
+   Source:
+   ftp://ftp.mayn.de/pub/really_old_stuff/apple/apple_unix/Sys_stuff/libUTIL-2.1.tar.gz>
+   ftp://arthur.barton.de/pub/unix/aux/libraries/libUTIL-2.1.tar.gz
+
+   This library contains functions that are common on other UNIX
+   systems but not on A/UX e.g. memmove(), strerror() und strdup().
 
 
-Hier die Zeiten von Alex System (Macintosh SE/30, 32 MB, A/UX 3.0.1):
-configure: 7:33, make: 12:02
+After installation of these packages just do a "./configure" and "make" to
+compile ngIRCd on A/UX.
 
 
+A few hints in case of errors:
+
+ - Either there's an 'install' on your system which is completely broken
+   (so 'configure' uses its own shell script) or use a fully functionable one.
+   There's at least one binary "out there" causing problems. The one
+   of the GNU fileutils works fine:
+   ftp://arthur.barton.de/pub/unix/aux/tools/fileutils-4.0.tar.gz
+
+ - The precompiled binary of the old 'bash' shouldn't be installed within
+   /bin (better do this in /usr/local/bin) because 'configure' would
+   choose it as its shell which wouldn't work.
+
+ - Because of limitations of /bin/sh on A/UX it can't be used to create
+   the 'config.status' script. Better rename /bin/sh to /bin/sh.AUX and
+   replace it by a symbolic link to /bin/ksh (ln -s /bin/ksh /bin/sh as
+   root).
+   These procedure should'nt cause you into problems and is recommended
+   even if you don't use ngIRCd.

+        accept = 6667
+        connect = 6668
+
+    This makes stunnel listen for incoming connections
+    on port 6667 and forward decrypted data to port 6668.
+    We call the connection 'ircs'. Stunnel will use this
+    name when logging connection attempts via syslog.
+    You can also use the name in /etc/hosts.{allow,deny}
+    if you run tcp-wrappers.
+
+    To make sure ngircd is listening on the port where
+    the decrypted data arrives, set
+
+        Ports = 6668
+
+    in your ngircd.conf.
+
+    Start stunnel and restart ngircd.
+
+    That's it.
+    Don't forget to activate ssl support in your irc client ;)

+ngIRCd supports one aspect of Zeroconf Networking[1]: Multicast DNS (mDNS[2])
+with DNS Service Discovery (DNS-SD[3]).
+
+To use this features you can use one of two APIs:
+
+  a) Apple "Bonjour" API as used by Mac OS X,
+  b) the Howl[4] Zeroconf library or the Howl compatibility layer
+     of the newer Avahi[5] library.
+
+When calling the configure script using the "--with-zeroconf" switch the
+avalable API will be autodetected and the required additional libraries will
+be linked to the ngircd binary as required.
+
+ngIRCd then registers a DNS-SD service for each port it is listening on using
+the service type "_ircu._tcp.".

-
-                         
-
-I. Standard-Installation
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-ngIRCd is developed for UNIX-like systems, which means, that the installation
-on a modern UNIX-like system should be no problem. The only thing is, that
-the system should be supported by GNU automake and GNU autoconf ("configure").
-
-The normal installation is like that:
-
-   1) tar xzf ngircd-<Version>.tar.gz
-   2) cd ngircd-<Version>
-   3) ./autogen.sh	[only necessary when using CVS]
-   4) ./configure
-   5) make
-   6) make install
-
-3): "autogen.sh"
-
-The first step, autogen.sh, is only necessary if the configure-script isn't
-already generated. This never happens in official ("stable") releases in
-tar.gz-archieves, but when using the CVS system.
-
-The next is therefore only interesting for developpers.
-
-autogen.sh produces the makefile.in's, which are necessary for the configure
-script it self, and some more files for make. For this step, there must be
-GNU automake and GNU autoconf (in recent versions).
-
-(again: "end users" do not need this step!)
-
-to 4): "./configure"
-
-The configure-script is used to detect local system dependancies.
-
-In the perfect case, configure should recognize all needed libraries, header
-and so on. If this shouldn't work, "./configure --help" shows more options.
-
-to 5): "make"
-
-The make command uses the Makefiles produced by configure and compiles the
-ngIRCd daemon.
-
-to 6): "make install"
-
-Use "make install" to install the server and a sample configuration file on
-the local system. For this step, root privileges are necessary. If there is
-already an older configuration file present, it won't be overwritten.
-
-This are the files that are installed:
-
-- /usr/local/sbin/ngircd: exectable server
-- /usr/local/etc/ngircd.conf: sample configuration, if not there
-
-
-II. Useful make-targets
-~~~~~~~~~~~~~~~~~~~~~~~
-
-The Makefile produced by the configure-script contain always these useful
-targets:
-
- - clean: delete every product from the compiler/linker
-   next step: -> make
-
- - distclean: plus erase all generated Makefiles
-   next step: -> ./configure
-
- - maintainer-clean: erease all automatic generated files
-   next step: -> ./autogen.sh
-
-
-III. Sample configuration file ngircd.conf
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-In the sample configuration file, there are comments beginning with "#" OR
-";" -- this is only for the better understanding of the code.
-
-The file is seperated in three blocks: [Global], [Operator], [Server]. In
-the [Gobal] part, there is the main configuration, like the server-name
-and the ports, on which the server should be listening. In the [Operator]
-section, the server-operators are defined and [Server] is the section,
-where the server-links are configured.
-
-The meaning of the variables in the configuration file is explained in the 
-"doc/sample-ngircd.conf", which is also the sample configuration file in
-/usr/local/etc after running "make install" (if you don't already have one).
-
-
-IV. Command line options
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-These parameters could be passed to the ngIRCd:
-
--f, --config <file>
-	The daemon uses the file <file> as configuration file rather than
-	the standard configuration /usr/local/etc/ngircd.conf.
-
--n, --nodaemon
-	ngIRCd should be running as a foreground process.
-
--p, --passive
-	Server-links won't be automatically established.
-
---configtest
-	Reads, validates and dumps the configuration file as interpreted
-	by the server. Then exits.
-
-Use "--help" to see a short help text describing all available parameters
-the server understands, with "--version" the ngIRCd shows its version
-number. In both cases the server exits after the output.

+.SH NAME
+ngIRCd \- the next generation IRC daemon
+.SH SYNOPSIS
+.B ngircd [
+.I Options
+.B ]
+.SH DESCRIPTION
+.BR ngIRCd
+is a free open source daemon for the Internet Relay Chat (IRC),
+developed under the GNU General Public License (GPL).
+.PP
+It's written from scratch and is not based upon the original IRCd like
+many others. It is easy to configure, supports server links (even with
+original ircd's) and runs on hosts with changing IP addresses (such as
+dial-in networks).
+.PP
+Currently supported platforms include AIX, A/UX, FreeBSD, HP-UX, IRIX,
+Linux, Mac OS X, NetBSD, OpenBSD, Solaris, and Windows with Cygwin.
+.PP
+As ngIRCd relies on UNIX standards and uses GNU automake and GNU autoconf
+there are good chances that it also supports other UNIX-based operating
+systems as well. By default, ngIRCd writes diagnostic and informational messages using
+the syslog mechanism.
+.SH OPTIONS
+The default behaviour of
+.BR ngircd
+is to read its standard configuration file (see below), to detach from the
+controlling terminal and to wait for clients.
+.PP
+You can use these options to modify this default:
+.TP
+\fB\-f\fR \fIfile\fR, \fB\-\-config\fR \fIfile\fR
+Use
+.I file
+as configuration file.
+.TP
+\fB\-n\fR, \fB\-\-nodaemon\fR
+Don't fork a child and don't detach from controlling terminal.
+All log messages go to the console and you can use CTRL-C to
+terminate the server.
+.TP
+\fB\-p\fR, \fB\-\-passive\fR
+Disable automatic connections to other servers. You can use the IRC command
+CONNECT later on as IRC Operator to link this ngIRCd to other servers.
+.TP
+\fB\-t\fR, \fB\-\-configtest\fR
+Read, validate and display the configuration; then exit.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Output version information and exit.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display a brief help text and exit.

+.SH DESCRIPTION
+.BR ngircd.conf
+is the configuration file of the
+.BR ngircd (8)
+Internet Relay Chat (IRC) daemon which you should adept to your local
+preferences and needs.
+.SH "FILE FORMAT"
+The file consists of sections and parameters. A section begins with the name
+of the section in square brackets and continues until the next section
+begins.
+.PP
+Sections contain parameters of the form
+.PP
+.RS
+.I name
+=
+.I value
+.RE
+.PP
+Empty lines and any line beginning with a semicolon (';') or a hash ('#')
+character are treated as a comment and will be ignored. Leading and trailing
+whitespaces are trimmed before any processing takes place.
+.PP
+The file format is line-based - that means, each non-empty newline-terminated
+line represents either a comment, a section name, or a parameter.
+.PP
+Section and parameter names are not case sensitive.
+.SH "SECTION OVERVIEW"
+The file can contain blocks of four types: [Global], [Operator], [Server],
+and [Channel].
+.PP
+The main configuration of the server is stored in the
+.I [Global]
+section, like the server name, administrative information and the
+ports on which the server should be listening. IRC operators of this
+server are defined in
+.I [Operator]
+blocks.
+.I [Server]
+is the section where server links are configured. And
+.I [Channel]
+blocks are used to configure pre-defined ("persistent") IRC channels.
+.PP
+There can be more than one [Operator], [Server] and [Channel] sections
+per configuration file, but only one [Global] section.
+.SH [GLOBAL]
+The
+.I [Global]
+section is used to define the server main configuration, like the server
+name and the ports on which the server should be listening.
+.TP
+\fBName\fR
+Server name in the IRC network, must contain at least one dot (".").
+.TP
+\fBInfo\fR
+Info text of the server. This will be shown by WHOIS and LINKS requests for
+example.
+.TP
+\fBAdminInfo1\fR, \fBAdminInfo2\fR, \fBAdminEMail\fR
+Information about the server and the administrator, used by the ADMIN
+command.
+.TP
+\fBPorts\fR
+Ports on which the server should listen. There may be more than one port,
+separated with ','. Default: 6667.
+.TP
+\fBListen\fR
+A comma seperated list of IP address on which the server should listen.
+If unset, the defaults value is "0.0.0.0", or, if ngircd was compiled
+with IPv6 support, "::,0.0.0.0", so the server listens on all configured
+IP addresses and interfaces by default.
+.TP
+\fBMotdFile\fR
+Text file with the "message of the day" (MOTD). This message will be shown
+to all users connecting to the server.
+.TP
+\fBMotdPhrase\fR
+A simple Phrase (<256 chars) if you don't want to use a MOTD file.
+If it is set no MotdFile will be read at all which can be handy if the
+daemon should run inside a chroot directory.
+.TP
+\fBServerUID\fR
+User ID under which the server should run; you can use the name of the user
+or the numerical ID.
+.PP
+.RS
+.B Attention:
+.br
+For this to work the server must have been
+started with root privileges! In addition, the configuration and MOTD files
+must be readable by this user, otherwise RESTART and REHASH won't work!
+.RE
+.TP
+\fBServerGID\fR
+Group ID under which the ngIRCd should run; you can use the name of the
+group or the numerical ID.
+.PP
+.RS
+.B Attention:
+.br
+For this to work the server must have
+been started with root privileges!
+.RE
+.TP
+\fBChrootDir\fR
+A directory to chroot in when everything is initialized. It doesn't need
+to be populated if ngIRCd is compiled as a static binary. By default ngIRCd
+won't use the chroot() feature.
+.PP
+.RS
+.B Attention:
+.br
+For this to work the server must have
+been started with root privileges!
+.RE
+.TP
+\fBPidFile\fR
+This tells ngIRCd to write its current process ID to a file. Note that the
+pidfile is written AFTER chroot and switching the user ID, i. e. the
+directory the pidfile resides in must be writeable by the ngIRCd user and
+exist in the chroot directory (if configured, see above).
+.RE
+.TP
+\fBPingTimeout\fR
+After <PingTimeout> seconds of inactivity the server will send a PING to
+the peer to test whether it is alive or not. Default: 120.
+.TP
+\fBPongTimeout\fR
+If a client fails to answer a PING with a PONG within <PongTimeout>
+seconds, it will be disconnected by the server. Default: 20.
+.TP
+\fBConnectRetry\fR
+The server tries every <ConnectRetry> seconds to establish a link to not yet
+(or no longer) connected servers. Default: 60.
+.TP
+\fBOperCanUseMode\fR
+Should IRC Operators be allowed to use the MODE command even if they are
+not(!) channel-operators? Default: no.
+.TP
+\fBOperServerMode\fR
+If OperCanUseMode is enabled, this may lead the compatibility problems with
+Servers that run the ircd-irc2 Software. This Option "masks" mode requests
+by non-chanops as if they were coming from the server. Default: no.
+.TP
+\fBPredefChannelsOnly\fR
+If enabled, no new channels can be created. Useful if
+you do not want to have channels other than those defined in
+the config file.
+Default: No.
+.TP
+\fBNoDNS\fR
+If enabled, ngircd will not make DNS lookups when clients connect.
+If you configure ngircd to connect to other servers, ngircd may still
+perform a DNS lookup if required.
+Default: No.
+.TP
+\fBConnectIPv4\fR
+Set this to no if you do not want ngircd to connect to other irc servers using ipv4.
+This allows use of ngircd in ipv6-only setups.
+Default: Yes.
+.TP
+\fBConnectIPv6\fR
+Set this to no if you do not want ngircd to connect to other irc servers using ipv6.
+Default: Yes.
+.TP
+\fBMaxConnections\fR
+Maximum number of simultaneous connection the server is allowed to accept
+(0: unlimited). Default: 0.
+.TP
+\fBMaxConnectionsIP\fR
+Maximum number of simultaneous connections from a single IP address that
+the server will accept (0: unlimited). This configuration options lowers
+the risk of denial of service attacks (DoS). Default: 5.
+.TP
+\fBMaxJoins\fR
+Maximum number of channels a user can be member of (0: no limit).
+Default: 10.
+.TP
+\fBMaxNickLength\fR
+Maximum length of an user nick name (Default: 9, as in RFC 2812). Please
+note that all servers in an IRC network MUST use the same maximum nick name
+length!
+.SH [OPERATOR]
+.I [Operator]
+sections are used to define IRC Operators. There may be more than one
+.I [Operator]
+block, one for each local operator.
+.TP
+\fBName\fR
+ID of the operator (may be different of the nick name).
+.TP
+\fBPassword\fR
+Password of the IRC operator.
+.TP
+\fBMask\fR
+Mask that is to be checked before an /OPER for this account is accepted.
+Example: nick!ident@*.example.com
+.SH [SERVER]
+Other servers are configured in
+.I [Server]
+sections. If you configure a port for the connection, then this ngIRCd
+tries to connect to to the other server on the given port (active);
+if not, it waits for the other server to connect (passive).
+.PP
+ngIRCd supports "server groups": You can assign an "ID" to every server
+with which you want this ngIRCd to link, and the daemon ensures that at
+any given time only one direct link exists to servers with the same ID.
+So if a server of a group won't answer, ngIRCd tries to connect to the next
+server in the given group (="with the same ID"), but never tries to connect
+to more than one server of this group simultaneously.
+.PP
+There may be more than one
+.I [Server]
+block.
+.TP
+\fBName\fR
+IRC name of the remote server.
+.TP
+\fBHost\fR
+Internet host name (or IP address) of the peer.
+.TP
+\fBBind\fR
+IP address to use as source IP for the outgoing connection. Default ist
+to let the operating system decide.
+.TP
+\fBPort\fR
+Port of the remote server to which ngIRCd should connect (active).
+If no port is assigned to a configured server, the daemon only waits for
+incoming connections (passive).
+.TP
+\fBMyPassword\fR
+Own password for this connection. This password has to be configured as
+"PeerPassword" on the other server. Must not have ':' as first character.
+.TP
+\fBPeerPassword\fR
+Foreign password for this connection. This password has to be configured as
+"MyPassword" on the other server.
+.TP
+\fBGroup\fR
+Group of this server (optional).
+.TP
+\fBPassive\fR
+Disable automatic connection even if port value is specified. Default: false.
+You can use the IRC Operator command CONNECT later on to create the link.
+.SH [CHANNEL]
+Pre-defined channels can be configured in
+.I [Channel]
+sections. Such channels are created by the server when starting up and even
+persist when there are no more members left.
+.PP
+Persistent channels are marked with the mode 'P', which can be set and unset
+by IRC operators like other modes on the fly.
+.PP
+There may be more than one
+.I [Channel]
+block.
+.TP
+\fBName\fR
+Name of the channel, including channel prefix ("#").
+.TP
+\fBTopic\fR
+Topic for this channel.
+.TP
+\fBModes\fR
+Initial channel modes.
+.TP
+\fBKey\fR
+Sets initial channel key (only relevant if mode k is set).
+.TP
+\fBMaxUsers\fR
+Set maximum user limit for this channel (only relevant if mode l is set).
