-HOW TO BUILD:
--------------
-1. Run the configure script. It will setup include/setup.h and the
- Makefiles to match your system:
- ./configure
-
- Type ./configure --help to see different options. Most people will not
- need to alter these.
-
-2. [DISCOURAGED] Edit the the "include/config.h" file. This allows you to
- change various options of how the ircd will operate. Usually the defaults
- are OK.
-
-3. "make" should build ircd.
-
-4. "make install" will install the ircd, config converter, and documents
- to the directory set by ./configure
-
-5. Edit example.conf in your install directory, and move it to "ircd.conf".
-
-6. Run the binary! ircd will look in the directory you are executing from
- for an ircd.conf first, then it will look to the directory local to itself.
- You may override these options by specifying a config file using:
- ./ircd -f path/to/ircd.conf
-
-Best of luck!

- GNU GENERAL PUBLIC LICENSE
- Version 1, February 1989
-
- Copyright (C) 1989 Free Software Foundation, Inc.
- 675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- Preamble
-
- The license agreements of most software companies try to keep users
-at the mercy of those companies. By contrast, our General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. The
-General Public License applies to the Free Software Foundation's
-software and to any other program whose authors commit to using it.
-You can use it for your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Specifically, the General Public License is designed to make
-sure that you have the freedom to give away or sell copies of free
-software, that you receive source code or can get it if you want it,
-that you can change the software or use pieces of it in new free
-programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of a such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must tell them their rights.
-
- We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-\f
- GNU GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any program or other work which
-contains a notice placed by the copyright holder saying it may be
-distributed under the terms of this General Public License. The
-"Program", below, refers to any such program or work, and a "work based
-on the Program" means either the Program or any work containing the
-Program or a portion of it, either verbatim or with modifications. Each
-licensee is addressed as "you".
-
- 1. You may copy and distribute verbatim copies of the Program's source
-code as you receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice and
-disclaimer of warranty; keep intact all the notices that refer to this
-General Public License and to the absence of any warranty; and give any
-other recipients of the Program a copy of this General Public License
-along with the Program. You may charge a fee for the physical act of
-transferring a copy.
-
- 2. You may modify your copy or copies of the Program or any portion of
-it, and copy and distribute such modifications under the terms of Paragraph
-1 above, provided that you also do the following:
-
- a) cause the modified files to carry prominent notices stating that
- you changed the files and the date of any change; and
-
- b) cause the whole of any work that you distribute or publish, that
- in whole or in part contains the Program or any part thereof, either
- with or without modifications, to be licensed at no charge to all
- third parties under the terms of this General Public License (except
- that you may choose to grant warranty protection to some or all
- third parties, at your option).
-
- c) If the modified program normally reads commands interactively when
- run, you must cause it, when started running for such interactive use
- in the simplest and most usual way, to print or display an
- announcement including an appropriate copyright notice and a notice
- that there is no warranty (or else, saying that you provide a
- warranty) and that users may redistribute the program under these
- conditions, and telling the user how to view a copy of this General
- Public License.
-
- d) You may charge a fee for the physical act of transferring a
- copy, and you may at your option offer warranty protection in
- exchange for a fee.
-
-Mere aggregation of another independent work with the Program (or its
-derivative) on a volume of a storage or distribution medium does not bring
-the other work under the scope of these terms.
-\f
- 3. You may copy and distribute the Program (or a portion or derivative of
-it, under Paragraph 2) in object code or executable form under the terms of
-Paragraphs 1 and 2 above provided that you also do one of the following:
-
- a) accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of
- Paragraphs 1 and 2 above; or,
-
- b) accompany it with a written offer, valid for at least three
- years, to give any third party free (except for a nominal charge
- for the cost of distribution) a complete machine-readable copy of the
- corresponding source code, to be distributed under the terms of
- Paragraphs 1 and 2 above; or,
-
- c) accompany it with the information you received as to where the
- corresponding source code may be obtained. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form alone.)
-
-Source code for a work means the preferred form of the work for making
-modifications to it. For an executable file, complete source code means
-all the source code for all modules it contains; but, as a special
-exception, it need not include source code for modules which are standard
-libraries that accompany the operating system on which the executable
-file runs, or for standard header files or definitions files that
-accompany that operating system.
-
- 4. You may not copy, modify, sublicense, distribute or transfer the
-Program except as expressly provided under this General Public License.
-Any attempt otherwise to copy, modify, sublicense, distribute or transfer
-the Program is void, and will automatically terminate your rights to use
-the Program under this License. However, parties who have received
-copies, or rights to use copies, from you under this General Public
-License will not have their licenses terminated so long as such parties
-remain in full compliance.
-
- 5. By copying, distributing or modifying the Program (or any work based
-on the Program) you indicate your acceptance of this license to do so,
-and all its terms and conditions.
-
- 6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the original
-licensor to copy, distribute or modify the Program subject to these
-terms and conditions. You may not impose any further restrictions on the
-recipients' exercise of the rights granted herein.
-\f
- 7. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time. Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number. If the Program
-specifies a version number of the license which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation. If the Program does not specify a version number of
-the license, you may choose any version ever published by the Free Software
-Foundation.
-
- 8. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission. For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this. Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
- NO WARRANTY
-
- 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
- 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-\f
- Appendix: How to Apply These Terms to Your New Programs
-
- If you develop a new program, and you want it to be of the greatest
-possible use to humanity, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these
-terms.
-
- To do so, attach the following notices to the program. It is safest to
-attach them to the start of each source file to most effectively convey
-the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
- <one line to give the program's name and a brief idea of what it does.>
- Copyright (C) 19yy <name of author>
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 1, or (at your option)
- any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) 19xx name of author
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the
-appropriate parts of the General Public License. Of course, the
-commands you use may be called something other than `show w' and `show
-c'; they could even be mouse-clicks or menu items--whatever suits your
-program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary. Here a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the
- program `Gnomovision' (a program to direct compilers to make passes
- at assemblers) written by James Hacker.

-\`configure' configures this package to adapt to many kinds of systems.
-
-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE. See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
- -h, --help display this help and exit
- --help=short display options specific to this package
- --help=recursive display the short help of all the included packages
- -V, --version display version information and exit
- -q, --quiet, --silent do not print \`checking...' messages
- --cache-file=FILE cache test results in FILE [disabled]
- -C, --config-cache alias for \`--cache-file=config.cache'
- -n, --no-create do not create output files
- --srcdir=DIR find the sources in DIR [configure dir or \`..']
-
-Installation directories:
- --prefix=PREFIX install architecture-independent files in PREFIX
- [$ac_default_prefix]
- --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
- [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
- --bindir=DIR user executables [EPREFIX/bin]
- --sbindir=DIR system admin executables [EPREFIX/sbin]
- --libexecdir=DIR program executables [EPREFIX/libexec]
- --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
- --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
- --localstatedir=DIR modifiable single-machine data [PREFIX/var]
- --libdir=DIR object code libraries [EPREFIX/lib]
- --includedir=DIR C header files [PREFIX/include]
- --oldincludedir=DIR C header files for non-gcc [/usr/include]
- --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
- --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
- --infodir=DIR info documentation [DATAROOTDIR/info]
- --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
- --mandir=DIR man documentation [DATAROOTDIR/man]
- --docdir=DIR documentation root [DATAROOTDIR/doc/PACKAGE]
- --htmldir=DIR html documentation [DOCDIR]
- --dvidir=DIR dvi documentation [DOCDIR]
- --pdfdir=DIR pdf documentation [DOCDIR]
- --psdir=DIR ps documentation [DOCDIR]

-Optional Features:
- --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
- --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
- --disable-hookmodules disable support for loadable hook modules
- --enable-openssl=DIR Enable OpenSSL support (DIR optional).
- --disable-openssl Disable OpenSSL support.
-
-Optional Packages:
- --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
- --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
- --with-socketengine=TYPE Set the socketengine type. Choices are:
- kqueue poll select
- --with-maxconnections=NUMBER Set the maximum number of sockets.
-
-Some influential environment variables:
- CC C compiler command
- CFLAGS C compiler flags
- LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
- nonstandard directory <lib dir>
- LIBS libraries to pass to the linker, e.g. -l<library>
- CPPFLAGS C/C++/Objective C preprocessor flags, e.g. -I<include dir> if
- you have headers in a nonstandard directory <include dir>
- CPP C preprocessor
-
-Use these variables to override the choices made by `configure' or to help
-it to find libraries and programs with nonstandard names/locations.

-Bahamut was taken on by a group of loosely knit coders that decided that
-Dreamforge just was eating up too much CPU to handle DALnet's growing user
-base. Originally starting out as the DFhybrid project, it slowly grew
-into the Bahamut project as the peices started falling together.
-
-Bahamut is based upon the hybrid IRCd, developed for EFnet, and we most
-surely wouldn't be where we are today without the dedication of the coders
-that developed that IRCd. The Hybrid team is outlined in the file
-included with this distribution, in doc/Hybrid-team. Please look over
-that file, those people are as much to credit for this as the people
-listed here.
-
-People who have supported the Bahamut project with code, support, or
-testing are, in alphabetical order:

-Aaron Wiebe epiphani@dal.net
-Chip Norkus wd@dal.net
-David Friedman driz@dal.net
-David Knepper dakal@dal.net

+++ /dev/null
-Changes for 1.4.36
-- Fix bug that caused bans to be expired ~1 million times on startup
-- Remove opers from fdlists that are set -o via SVSMODE
-- Only show IPs of unknowns or clients to opers in /trace
-- Use OpenSSL instead of GMP for encryption (much cleaner! :)
-- Remove non-SSJOIN support
-- Allow for a server to detect it is out of synch, and request a
- channel resynch from an upstream hub
-- Fix remote /stats k/K/a bug (it works now :)
-- Optimize some sendto() things that are used a lot
-- Add usermode +I (server hiding)
- - Fix /whois, /admin, /who, etc to not allow a user to discover which
- server a +I user is on
-- Don't let *MY* opers /kill U: lined things (but pass on kills destined for them already)
-- Chatops don't require you to be +gb (now, just +b)
-- Various typos fixed
-- No longer complain if a user is already on a +i channel, and they /join it
-- Use hash tables for very common res functions, which were taking up
- as much as 80% of CPU time in a pooled server
-- add a command, /userip, for opers. Works just like /userhost.
-- Allow /who +c @#channel +#channel @+#channel for more refined /who listings
-- Add a /who flag for opers, +/-t, clients who have been on for more/less than <param> seconds
-- Don't let opers get stuck in weird anti-flooding bugs (oper recvq lock bug)
-- When an oper deopers, they are returned to the appropriate client class
-- Allow opers to /who +l <class> for local clients (class = Y: class)
-- Send optimizations for high-volume server connections
-- Remove fdlists for lists of clients and instead use linked lists for things:
- - recvq clients, instead of searching through *all* clients
- - listing clients, ditto
-- Remove certain things which actually caused poor server operation:
- - HTM - relax sending out when we have high incoming traffic.
- This actually causes a nasty bursty cycle.
- - busy clients
- This was taking up a great deal of CPU time to save CPU time. Hmm.
-- Rewrite the entire base socket engine; now supports kqueue on freebsd.
- - Poll() and select() use persistant states, so these should be twice as fast as well.
- - Stop remapping fds. What's the point?
-- /stats w reports fd map (don't use this on a large server! :)
-- /stats z is more informative
-- Hide the source servers of numerics (mask them with me.name)
-- Hide /kill sources in quit messages (still in +s, though) and in messages
- sent to killed client
-- Hide split sources in quit messages
-- Add a LINKSCONTROL command which allows a services-controlled /links list
-- Better server traffic accounting in /stats ? (uses a moving average instead of a plain average)
-- Fix a bug in which connecting servers will always remove a key if the channel exists (argh!)
-- Correctly propogate cmode +O
-- Show more squelched info in /whois to opers
-- Be smarter about broken FD_SETSIZE implementations
-- Crash if we try to free something twice in the block allocator, produces a useful coredump
- instead of confused opers and an unrelated crash hours later.
-- ability to lock /lusers output via services for a dynamic amount of time
-- Fix 'ghost channels' where I create a channel but none of the users in it exist to me
-- Allow /who +i ip/cidr and /who +I (show IPs only) for opers
-- SAJOIN, like SAMODE for joining channels. Joins through all modes, sends a globop.
-- Local servers notify the channel of an invite, not the server the invitee is on
-- Remove the drone module, replace it with a powerful and generic module system that
- has event-based hooks.
-- Streamline some privmsg stuff, fix a few bugs.
-- Fix a bug in which an IP ban on 1.2.3.4* wouldn't work.
-- Dehybridize some things.
-- SVSMODE +T, which sets a "client type" that can be seen in a /who +T <clienttype>
-- Don't allow ',' in channel keys
-- Fix umode +r/-r notification to clients
-- Pretty print some things in /stats ?
-- Remove support for non-NOQUIT servers
-- Modes sent from servers come from the local server now
-- Complain about /who +<flag>, where <flag> isn't valid, instead of sending the entire client list
-- Move SQLINES and SGLINES into another hash-based structure for fast lookups
-- Add SVSHOLD, which adds a local temp qline for a nick for N seconds, intended to replace
- enforcers in services.
-- Make HTM work on outgoing traffic (the part of HTM that limits sending lots of expensive
- things like /list)
-- Don't complain about servers relinking that look 'juped'
- (don't complain if the server that already exists is U: lined, unless I actually have a
- .conf U: line for it!)
-- Compile with GCC3!
-- Nicer umode separation, ie what used to come in as *** Notice -- comes in as:
- +d : *** Debug --
- +y : *** Spy --
- +c : *** Client --
-- Channel join throttling (cmode +j, but disabled for user changes by default to be compatible with
- pre-1.4.36), defaults to 8 network non-split joins in 4 seconds before saying channel is full.
-- Fix the DEBUGMODE pattern string exploit
-
-Changes for 1.4.35
-- Source address support on /connect problem fixed
-- Squelching added, umode +x or +X (+X is silent squelch), this
- prevents the user from doing certain online tasks such as privmsg.
- Meant to be set by a U: lined server or client using SVSMODE.
-- Complete rewrite of the kline/akill/zline system. (s)zlines no longer
- exist. K: lines set on IP addresses without username portions (or *)
- are treated as Z: lines used to be. CIDR banning is now supported
- in all K: line/akill bans (ie, 204.127.54.112/28).
-- +F usermode bypasses ircd's recvq throttling for opers
-- Improved handling under high load situations
-- Ban munching bug introduced in 1.4.34 is fixed
-- /rehash GC now works
-- lots of sendto_ops_lev changed to sendto_realops_lev for speed

- write to locations of memory that weren't ours :)
-- Fix O: flags that just didn't work as advertised
-- Moved rejection notices to umode +j (re_j_ection)
-- Moved KILL messages from U: lined clients to umode +K (oper only)
-- Support for a loadable drone module, compile with --enable-dronemodule,
- ircd tries to load drone.so from DPATH on startup or on /rehash drones,
- read src/drone.c to view the interface
-- /stats t shows more information
-- Various code cleanup and readability fixes
-- Users and opers will now recieve a different output to '/who ?'.
-- When 'HELP_FORWARD_HS' is defined, non-opers /quote help requests
- will be forwarded to HelpServ.
-
-Changes for 1.4.34
-- Don't use FD_SETSIZE at all if USE_POLL is defined
-- Fixed a server negotiation bug that could break apart the network
- when autoconnects and user connects were done at the same instant
-- Fix a bug where PART messages were not sent to 'userB' when 'userA's
- QUIT message was squelched on more than 1 channel
-- Fixed split riding ability left over from hybrid (where a channel
- with a newer TS could 'take over' if it had ops and the older TS channel
- did not)
-- Fixed 'topic riding' ability that allowed topics from newer TS'd channels
- to propogate.
-- Fixed channel ban desync on netjoin
-- all channel modes are now sent with a TS
-- Target limiting anti-spam measure installed
-- Reject acebot-style drones by default
-- Minor fixes to prevent annoying auth error messages

-Clone Limiting
-==============
-Bahamut supports limiting the number of connections from a single place,
-and this file describes the configuration for that feature. There are two
-kinds of places: a "host" is a single IP (10.0.0.1); a "site" is a single
-/24 block of IPs (10.0.0.*). Clones are the number of connections from a
-given place.
-
-Two types of clone limits are supported: local clones are the number of
-connections from a place on this server only; global clones refer to
-connections on the entire network. When a clone limit is reached, the
-server denies further connections from that place.
-
-
-Local clone limiting
---------------------
-The default local clone limits are set using the local_clones token in the
-Options block in ircd.conf; see doc/reference.conf for details. In the
-absence of more specific limits, the defaults will regulate all connections
-to the server.
-
-Local limits set using the maxclones token in a Class block override the
-defaults; this is typically used with Allow blocks to provide exemptions
-for specific hosts. When a Class block defines a host limit, clients in
-that class are implicitly exempt from the default site limit.
-
-Example:
-
- options { local_clones 1:10; };
- class { name special; maxclones 5; };
- allow { host *@10.0.0.1; class special; };
-
- Suppose there is one client each connected from 10.0.0.2 - 9 (8 clients
- from 10.0.0.*). If another client from 10.0.0.2 tries to connect, it
- will be rejected because the default limit of 1 connection per host was
- reached. Five more clients from 10.0.0.1 will be allowed to connect,
- because the "special" class allows up to 5 connections from a single
- host.
-
- Note that because the class did not provide a site limit, five clients
- from 10.0.0.1 will always be allowed to connect, despite the default
- limit of 10 per site. To maintain a site limit for these clients,
- specify one in the class maxclones statement:
-
- class { name special; maxclones 5:10; };
-
-The default limits can be changed online using the SET DEFLCLONES command.
-Note that this setting is not saved and will be lost when the server is
-restarted; it is useful for testing or setting temporary limits.
-
- SET DEFLCLONES - to display both limits
- SET DEFLCLONES <host limit> - to set the host limit
- SET DEFLCLONES <host limit>:<site limit> - to set both limits
-
- Supplying a limit of 0 will revert to the internal default.
-
-Specific local limits can be set online using the SET LCLONES command;
-these are called "soft" limits and override all other local limits.
-A soft host limit also provides an implicit exemption from class and
-default site limits. Like DEFLCLONES, these are temporary.
-
- SET LCLONES <host/site> - to display the limit
- SET LCLONES <host/site> <limit> - to set the limit
-
- Use a specific host or site mask, e.g. "10.0.0.1". Supplying a limit
- of 0 will remove the soft limit; class and default limits will be used
- instead.
-
-Note that it is possible to create some interesting configurations using
-the class setting. For example, this would effectively allow 5 clones from
-a specific ident@host, since only clients matching the allow block would get
-the increased per-host limit:
-
- options { local_clones 1; };
- class { name special; maxclones 5; };
- allow { host ident@host; class special; };
-
-
-Global clone limiting
----------------------
-This works in basically the same way as local clone limiting, except that
-it considers connections on the entire network, and is intended to be
-managed by network services.
-
-The default global clone limits are set using the global_clones token in
-the Options block in ircd.conf; see doc/reference.conf for details. In the
-absence of more specific limits, the defaults will regulate all connections
-to the server. Note that to be effective, all servers must share the same
-global limits. A server can only reject new connections to itself; it
-cannot tell other servers to do so.
-
-Example:
-
- options { global_clones 2:6; };
-
- If there are six clients on other servers on the network, from various
- addresses in the 10.0.0.* block, this server will not allow another
- connection from 10.0.0.1, because the global site limit has already
- been reached. However, if the remote servers have a higher default,
- they will still allow more clients to connect.
-
-Network services can set specific limits using the SVSCLONE command; these
-are referred to as "hard" global clone limits. A hard host limit provides
-an implicit exemption from the default site limit. The command syntax is
-provided here for services authors to reference; it is not accessible to
-clients.
-
- SVSCLONE <host/site> <limit> - to set the limit
-
- Use a specific host or site mask, e.g. "10.0.0.*". Supplying a limit
- of 0 will remove the hard limit. This setting is stored by all servers
- and propagated on netburst, in a manner similar to SQLINES.
-
-The default limits can be changed online using the SET DEFGCLONES command.
-Note that this setting is not saved and will be lost when the server is
-restarted; it is useful for testing or setting temporary limits.
-
- SET DEFGCLONES - to display both limits
- SET DEFGCLONES <host limit> - to set the host limit
- SET DEFGCLONES <host limit>:<site limit> - to set both limits
-
- Supplying a limit of 0 will revert to the internal default.
-
-Specific global limits can be set online using the SET GCLONES command;
-these are called "soft" global clone limits and override the defaults.
-A lower soft limit will also override a service-set hard limit, but it is
-not possible to set a soft limit higher than a hard one. Like DEFGCLONES,
-these are temporary.
-
- SET GCLONES <host/site> - to display the limits
- SET GCLONES <host/site> <limit> - to set the soft limit
-
- Use a specific host or site mask, e.g. "10.0.0.1". Supplying a limit
- of 0 will remove the soft limit; hard and default limits will be used
- instead.
-
-
-Monitoring
-----------
-Rejection notices for clone connections are sent to usermode +j, in the
-following format:
-
- clone <nick!user@host> (<place> <online>/<limit> <type> <from>)
-
- <nick!user@host> is the rejected client
- <place> is the host or site mask, e.g. "10.0.0.*"
- <online> is the number of clients currently online from that place
- <limit> is the limit for that place
- <type> is "local" or "global"
- <from> is where the limit was set:
- "default", "soft", "hard", "class <name>"
-
-General statistics about the clones system are available on STATS d.
-
-A list of specific limits is available on STATS D, returned on numeric 225:
-
- D <host/site> <soft local limit> <soft global> <hard global>
-
-
-Notes
------
-When local and global limits differ, the lowest limit applies. This means
-you should carefully choose the defaults and how you want to manage the
-specific limits, as working with both types of limits at once can be
-difficult.
-
-When a client is rejected, its exit reason is one of:
-
- Too many connections from your host
- Too many connections from your site
-
-It is not told which specific limit was reached.
-
-Very little host/site mask validation is done for the online commands; it
-is possible to query and set limits for completely bogus masks. Such
-limits will be retained but never used.

-Bahamut Hook Module System [2003-10-13]
-
-First released in Bahamut 1.4.36, the hook module system permits outside modules
-to be 'hooked' into bahamut without having to modify the core source tree.
-This is to allow other groups to write code to benefit IRCD that serve
-specific functions. As an example, some groups write modules to block
-common trojan / drone patterns.
-
-Once a module has been built, hooking it into the system is fairly simple.
-The components that are used, are:
-
-1. A modules/ directory where the shared modules themselves are stored
-
-To enable the hook module system, you must issue --enable-hook-modules
-at configuration time. Example:
-
-./configure --enable-hook-modules
-
-(As of bahamut 1.8, this is implicitely assumed.)
-
----
-
-1. modules/ directory
-
-This directory stores the shared modules that you wish to hook into bahamut.
-The modules/ directory is found in the same directory as your server
-configuration files (eg: bahamut-release/modules)
-
----
-
-USER COMMANDS TO CONTROL MODULES
-
-There are a few new commands to control modules. They are all accessed
-by using /quote module <command>.

-
-* I compile and everything seems fine during the compiling, but when it
-comes time for the program to link, I get errors complaining about dns and

-
-You need to make sure IRCDLIBS in the toplevel Makefile includes -lresolv

-The hybrid team is a group of ircd coders who were frustrated
-with the instability and all-out "dirtiness" of the efnet ircd's
-available. "hybrid" is the name for the collective efforts of a group
-of people, all of us.
-
-Anyone is welcome to contribute to this effort..
-
-We have run the code through "purify", a commercial program designed
-to find memory leaks. The code has been mostly prototyped. Profiling has also
-been done to catch slow portions of the code. Portions of "crufty" code have
-been re-written. We have also looked at making the code as easy to setup
-up and run as possible using configure, checking header files etc.
-Finally speed enhancements and other enhancements have been made to this ircd.
-
-That is not to say that there are still not bugs, There are always bugs.

-Internet Relay Chat Operator Etiquette Guide
-
-May, 1992
-
-Welcome! You've either been selected to be an IRC Operator or you have set
-up your server and thus have taken on the dual task of IRC Server
-Administrator and IRC Operator. Your future days will be filled with hours
-of fun chatting on IRC, and then wondering why everyone you talked to went
-away, because the links had apparently broken.
-
-Linking:
-========
-
-You will be assigned links from the IRC Routing Coordinators. Please
-use these links and these links ONLY. The links have been designed to
-maximize efficiency and make delays in chatting minimal. You will
-usually be given two links, one to each regional backbone site.
-Connect to the primary site first and then to the secondary site. You
-should not need to connect to any other sites. You will be informed if
-this policy changes.
-
-Kills
-=====
-
-/kill is a special operator command. You should use it with
-care, and only if absolutely needed. The format is as follows:
-/kill NICKNAME comment. Comment can be a phrase of almost any length
-(within reason) and should be used for specifying the reason of the kill.
-Example: /kill Trillian She's a Ghost
-IRC Ghosts are created after a net split has occured and the net has yet to
-relink.
-
-/wallops PHRASE This is used to talk to those users who have their
-user mode set to +w. /wallops used to be a way for operators to talk
-about important matters in linking etc., but it has little use
-nowadays.
-
-/TRACE command /TRACE is useful to know what servers are connected to
-what. Sometimes /trace can be confusing, especially if you are using
-it for the first time. Here is an example of a trace from
-stekt1.oulu.fi to cdc835.cdc.polimi.it.
-
-/TRACE cdc835.cdc.polimi.it
-
-*** Link stekt1.oulu.fi<2.7.2> ==> cdc835.cdc.polimi.it
-*** Link rieska.oulu.fi<2.7.1>e ==> cdc835.cdc.polimi.it
-*** Link nic.funet.fi<2.7.1>e ==> cdc835.cdc.polimi.it
-*** Link ircserver.et.tudelft.nl<2.7.1>e ==> cdc835.cdc.polimi.it
-*** Link vesuv.unisg.ch<2.7.1>e ==> cdc835.cdc.polimi.it
-*** Link apollo.di.unipi.it<2.7.1>e ==> cdc835.cdc.polimi.it
-*** Oper Class[10] ==> Allanon[cdc835.cdc.polimi.it]
-*** User Class[11] ==> Lupandy[plus2.usr.dsi.unimi.it]
-*** Serv Class[3] ==> apollo.di.unipi.it[131.114.4.36] 132S 445C
-*** User Class[11] ==> Punk[pluto.sm.dsi.unimi.it]
-*** User Class[11] ==> TheEdge[pluto.sm.dsi.unimi.it]
-*** User Class[10] ==> Mork[cdc835.cdc.polimi.it]
-*** User Class[11] ==> Lollo[c700-2.sm.dsi.unimi.it]
-*** User Class[11] ==> Attila[hp2.sm.dsi.unimi.it]
-*** Class 0 Entries linked 1
-*** Class 11 Entries linked 5
-*** Class 10 Entries linked 2
-*** Class 3 Entries linked 1
-
-From this output you can see that the route goes first to
-rieska.oulu.fi (running version 2.7.1e), then nic.funet.fi,
-ircserver.et.tudelft.nl, vesuv.unisg.ch, and apollo.di.unipi.it, after
-which cdc835 is the next server. Then we see the connections on
-cdc835: One operator (Allanon) and 6 users are on line. The class of
-each connection is given. There is only one server connected to cdc835
-at the moment, and that server is apollo.di.unipi.it (cdc835 is said
-to be a "leaf" server at the moment). The numbers 132S 445C in the end
-of line tell us, that there are 132 servers and 445 clients connected
-to the servers from apollo onwards. Finally we see a grand total of
-connections in each connection class.
-
-
-/SQUIT server {comment}
- /squit isolates a specified server from the next closest server, when
-you look at it along the trace path starting from your server.
-This is usually used in conjunction with CONNECT (explained later) to
-reroute traffic. This will be described in detail in the section
-"routing", preceding CONNECT.
-
- Usage (and examples):
-
- /squit E
-
- If the network looks like this initially (and you are on server A)
-
-
- A <---> B <---> C <---> D
- ^
- |
- v
- G <---> E <---> F <---> ... (rest of the net)
-
-
- Then after issuing the previous /squit the network would look like this:
-
- A <---> B <---> C <---> D
-
-
- G <---> E <---> F <---> ...
-
-
- /squit E {comment}
-
- It usually helps to give a reason why you are sending a
- SQUIT for a server. This can be accomplished by sending
- the command "/squit server This link is making the US route
- through Finland". The SQUIT will then be sent out, and the
- server sending the squit will WALLOP sending the comment
- so all operators can see it.
-
-/CONNECT server {portnum server2}
- /connect is used to establish a link between two servers. These
-connections must be authorized by each server's ircd.conf file, but
-any operator can issue a CONNECT between authorized servers. This
-command is most often used in conjunction with SQUIT to reroute
-traffic.
- If only one argument is given, this command causes the server you
-are on to attempt to connect to the server specified. For example,
-"/connect B" (in the previous example) would cause your server (A) to
-connect to B.
- Suppose you wanted to reconnect server F to server E? You cannot
-contact server F since it is no longer part of your network. However,
-you can tell server E to connect to it. A remote CONNECT can be issued
-to server E.
-
- Examples (assume you are on server A):
-
- /connect B
-
- If the network initially looks like this:
-
- A B <---> ... (rest of network)
-
- Then afterwards (if the connection succeeds) the network will look
- like this:
-
- A <---> B <---> ...
-
-
- In the example where you wanted to reconnect server E to F, the
- following syntax would be appropriate (note: we are assuming that
- F's irc socket port is 6667, which is the default)
-
- /connect F 6667 E
-
- If the network initially looks like this:
-
- A <---> B <---> C <---> D
- ^
- |
- v
- G <---> E F <---> ...
-
- Then after your CONNECT request the network topology will look like this:
-
- A <---> B <---> C <---> D
- ^
- |
- v
- G <---> E <---> F <---> ...
-
- Be careful when connecting servers that you know which command to
- use! If you simply issued "/connect F" from your server, the
- network would look like this:
-
-
- ... <---> F <---> A <---> B <---> C <---> D
- ^
- |
- v
- G <---> E
-
- which for various reasons (discussed below) might be very
- undesirable.
-
-Routing
-=======
-
- When and how should you do rerouting? This depends on where your
-server is topologically located and whether you route traffic. If you
-are a leaf node (i.e. only connect to one server at a time) then
-chances are you won't need to do any routing at all. Your ircd.conf
-file should be written to connect to the best possible servers first
-before trying alternates. At the most, you may decide to squit an
-alternate server and connect to your primary if/when it goes back up.
-This only involves local squits, however.
-
- If you are operating a backbone site, you may find yourself
-rerouting things quite often. If the servers badger.ugcs.caltech.edu
-(Pasadena, CA), irc.mit.edu (Boston, MA), minnie.cc.utexas.edu
-(Austin, TX) and ucsu.colorado.edu (Boulder, CO) were routing traffic
-in the following way:
-
- ... <---> minnie <---> badger <---> bucsd <---> ucsu <---> ...
-
-It would make sense to either squit ucsu and reconnect it to minnie,
-or disconnect minnie from badger and connect to ucsu, because
-topologically (and geographically) ucsu and minnie are rather close.
-There are occasions when US traffic for some reasons winds up being
-routed through Australia. This is another case where traffic should
-definitely be rerouted. However, there are sometimes occasions when
-routing is going through "backdoor" methods. If you see something
-totally outrageous (like the east coast and the west coast being
-connected by eff.org) please ask for example on channel #twilight_zone
-before you send any squits, because chances are, it's like that for a
-reason.
-
- Of course, any operator can remotely squit or connect servers, so
-if you see a problem and you're sure you know how to fix it, it's a
-good idea to do so. If the operator of a server which is is being
-routed poorly is online, it's probably best to contact him/her first,
-though.
-
- Chances are that hub operators will be more familiar with the
-general topology of the network and which servers connect to which
-(which is why most of the manual routing is left to them), so if you
-have any problems, talk to the other operators on operator channels
-(#twilight_zone, #eu-opers etc.) That's what they are there for!
- Also, be aware that servers will notify all the operators online of
-remote SQUITs and CONNECTs via WALLOPS.
-
-Please let us know if there should be any additions to this guide. Again,
-this is not MANDATORY, this is just a GUIDE. Please conduct yourself as
-an IRC Operator would...you are looked upon for assistance, both emotional
-and mental.

-* m_server() now quietly ignores clients that try to use SERVER
-* removed NOTE code, removed SUMMON code, gutted USERS
-* added automatic timestamps to comments of quote KLINE and DLINE
-* changed failure notice for clients bouncing off ACKPATCH
- to "Only one connection at a time allowed from your hostname"
-* cleanup to channel.c
-* format() mod to check for NULL args (di)
-* removed more useless crap (UPHOST, VMS, etc) from config.h
-* #undef F_LINES fixed
-* oper WALLOPS changed to OPERWALL (code taken from csr30)
-* BSDI 3.0 FD_ALLOC support (db)
-# changed output of STATS D
-* Removed Q: line support
-* cleaned up find_conf_ip (db)
-* fixed crypt() usage to work on systems with longer salts
- (ie FreeBSD without DES libs)
-* various spelling fixes (db)
-* N: line checking in m_server() (db)
-* WARN_NO_NLINE define added to config.h
-
------------------------------------------------------------------------------
-+hybrid-3 (6/17/97):
-* Added USRIP command. This command returns user@ip in a USERHOST
- reply for local clients only. Requests for remote nicks are treated
- as though the nick doesn't exist.
-* Switched to Dianora's faster dich_conf.c
-* Check for invalid characters (see RFC1035) in hostnames
-* Fixed problem with coring due to invalid hostnames on non-local users
-* TSora version 3
-* Turned D_LINE support back on
-* Numerous changes to Config script, may actually work now
-* Additional OS defs in Makefile
-* Minor cleanup in include/config.h
-# created new INSTALL document
-
------------------------------------------------------------------------------
-+hybrid-2 (4/12/97):
-This is ircd2.8/th.v5a.3 with the WHO, WHOWAS, and IsMember() code
-from Comstud's irc2.8.21CSr29. Please send email to Jon Lusky
-<irc@vol.com> if you find problems with it.
-
-Relevant excerpt from irc2.8.21+CSr29/README.CS:
-3) /whowas code totally rewritten. This code is better than Avalon's
- ever was. You can now raise NICKNAMEHISTORYLENGTH in config.h to
- a value that makes sense with today's number of clients. Without
- rewriting, you could expect server lockup, mostly during splits.
- These changes should lower CPU usage quite a bit, especially during
- splits.
-4) /who code tweaked. IsMember() = CPU hog...IsMember() has been changed
- and m_who does less find_user_link()s now...much less. This is
- a big reducer of CPU usage. Also another "bug" was removed from
- m_who that can possibly cause server lockups. The possibility still
- remains, though...not sure how to improve it further without totally
- breaking /who.
-5) This goes with #4, but...
- /who nickname was optimized tremendously. However, this breaks /who
- if you do /who username and username happens to match a nickname.
- Oh well...too bad.
-

-+hybrid-1 never really existed

-#
-# You only need an ircd.conf (IRC server configuration file) if you are

-# is not necessary.
-#
-# This file will explain the various lines in the IRC server

-# "chkconf", provided in the server distribution (and when you do "make

-# This document modified for use by the DALnet IRC network and its upgraded
-# server versions by Russell on 10/22/95.
-#
-# This document updated to comform to current ircd changes and features by

-# Updated for Bahamut by driz 3/3/2001
-#
-# The options for whether a line is needed or not are:
-# MANDATORY: you absolutely MUST have this line
-# NETWORKED: you must have this line if you are connecting this irc
-# server to any other server (servers can run standalone).
-# SUGGESTED: it is highly suggested that you use this line
-# OPTIONAL: it's completely up to you whether to define this or not
-# DISCOURAGED: you really really should not use this line if at all
-# possible.
-# OBSOLETE: an old or out of date line that isn't needed.
-#
-# MANDATORY lines are absolute *musts*, that is, if you do not have this
-# line then your server will not work properly. SUGGESTED lines are
-# close-to-mandatory (that is, the server will run without it, but you are
-# highly encouraged to use these lines).
-#
-# Note that "*" in a field indicates an "unused" field.
-#
-# ========================================================================
-# NOTE! this entire configuration file is read UPSIDE-DOWN! So if you have
-# to put something in a specific order (for example, client-connection
-# lines), put them in reverse order!
-# ========================================================================
-#
-# M: [MANDATORY]. This line sets your server's name, description, port
-# number, and IP address to bind to. Fields, in order, are:
-#
-# If you are compiling this server for use on DALnet, port number 7000
-# as the default is recommended. If you leave IP address field blank or
-# *, it defaults to binding all local IP addresses on the machine.
-#
-# M:hostname:IP:Description Of Your Server:7000
-#
-M:server.dal.net:*:East Coast DALnet Server:7000
-#
-# A: [MANDATORY]. This line lists your administrative information
-# (contact address, etc). To view this information, /admin (server) will
-# show it to you.
-#
-# The A: line has no set information, in fact, you can put arbitrary text
-# in there if you wish (it is encouraged that you put at *least* a contact
-# address for a person responsible for the irc server, however)
-#
-A:Generic Internet Access:Admin John Doe:jdoe@generic.com
-#
-# Y: [SUGGESTED]. These lines define connection classes. Connection
-# classes allow you to fine-tune your client and server connections. It is
-# suggested that clients and servers be placed in seperate classes, and if
-# you have lots of server connections (if you do have lots of servers you
-# shouldn't be reading this file :-) each set of servers (defined
-# arbitrarily by you) should have its own class. If you have clients
-# coming in from lots of different sites, you may want to seperate them
-# out into classes. For instance, you may want to put local users in one
-# class, with remote users in another class.
-#
-# The class numbers are not arbitrary. In auto-connecting servers -- that
-# is, servers that you have a port number (e.g. 6667) on the end of the C:
-# line (see below) the higher the number the higher the priority in
-# auto-connecting.
-#
-# The fields in order are: class number, ping frequency (in seconds),
-# connect frequency (in seconds), maximum number of links (used for
-# auto-connecting, and for limiting the number of clients in that class),
-# and sendq (this overrides any value set in include/config.h for #define
-# MAXSENDQLENGTH).
-#
-# Note that it is a good idea to have ping frequency the same at both ends
-# of the link.
-#
-# in this case, connect-frequency is 0 indicating that this is a client
-# class (servers never connect to clients, it is the other way around).
-Y:1:90:0:20:100000
-#
-# These are the recommended server Y:lines for connecting to dalnet.
-# In addition to these you should have at *least* one client class, and one
-# oper class (see O:lines). By convention on dalnet, these are usually
-# numbered from 5 to 10.
-#
-# Class 50 - Hub to hub, autoconnect
-Y:50:90:60:1:15000000
-#
-# Class 51 - Hub to hub, no autoconnect
-Y:51:90:60:0:12000000
-#
-# Class 30 - Hub to US leaf
-Y:30:90:0:0:5000000
-#
-# Class 32 - Hub to EU leaf
-Y:32:180:0:0:5000000
-#
-# Class 34 - Hub to AU leaf
-Y:34:300:0:0:5000000
-#
-# Class 40 - US leaf to hub, autoconnect
-Y:40:90:90:1:5000000
-#
-# Class 41 - US leaf to hub, no autoconnect
-Y:41:90:90:0:5000000
-#
-# Class 42 - EU leaf hub
-Y:42:180:90:1:5000000
-#
-# Class 44 - AU leaf to hub
-Y:44:300:120:1:5000000
-#
-# I: [MANDATORY]. The I: lines are client-authorization lines. Without
-# these lines, no clients will be able to connect to your server.
-# Wildcards ("*") are permitted. Passwords are also permitted (clients can
-# be configured to send passwords).
-#
-# Ident (for more information on this, see rfc1413) can also be used by
-# placing a @ in the appropriate fields.
-#
-# Fields are as follows:
-# I:IP-address-mask:optional password:domain-mask::connection class (opt)
-#
-# With a password..... This will allow anyone from anywhere to connect
-# as long as they know the password ("foobar"). Note listing this I: line
-# first, it will be read *last*, meaning it is the "fall-through". That
-# is, anyone who doesn't match the I: lines listed below must know the
-# password ("foobar") to connect.
-#
-I:*@*:foobar:*@*::1
-# This is a standard vanilla I: line which will permit anyone with an IP
-# address starting with 205.133 OR with a hostname ending in
-# .toledolink.com to connect to the server. NOTE, the ircd matches on the
-# *right-most* match, so if I connect as rmiller@glass.toledolink.com
-# (which is rmiller@205.133.127.8) I will show up on irc as
-# rmiller@glass.toledolink.com since that is the first match it found.
-# (Even though the second match is valid).
-I:205.133.*::*.toledolink.com::1
-#
-# using ident
-I:*@205.133.*::*@*.toledolink.com::1
-# and you can even specify just certain usernames running ident (as long
-# as the client's site is running the ident daemon):
-I:NOMATCH::rmiller@glass.toledolink.com::1
-# putting NOMATCH in the first field will stop the ircd from matching
-# automatically against the IP address and it will force the server to
-# match against the hostname. (the "NOMATCH" string is not mandatory, you
-# can use any arbitrary text in the first field).
-#
-#
-# O: [OPTIONAL]. These lines define operator access. You do not need to
-# have an operator to run a server. A well configured leaf site should not
-# need an operator online, if it's connections are well defined, the irc
-# administrator can use kill -HUP on the ircd to reload the configuration
-# file.
-# The fields are as follows:
-# O:hostname (ident "@" permitted):password:NickName:AccessFlags:class
-# if the person in "NickName" is not coming from the hostname defined in
-# the first field then the person will get the error message "No O: lines
-# for your host".
-# NOTE that since Crypted Passwords are defined by default in
-# include/config.h this text probably will not be plaintext. See
-# ircd/crypt/README for more information.
-#
-# class is the Y:Line class you want this operator to end up in after they
-# have successfully /oper'd.
-#
-# Access flags may be left blank, or * to give full access rights. Flags
-# are in the form of single characters making a string. Any combination
-# of the following can be used(these are cAsE sensitive characters):
-#
-# r = access to /rehash server
-# R = access to /restart server
-# D = access to /die server
-# g = oper can send /globops
-# w = oper can send /wallops
-# l = oper can send /locops
-# c = access to do local /squits and /connects
-# C = access to do remote /squits and /connects
-# k = access to do local /kills
-# K = access to do global /kills
-# b = oper can /kline users from server
-# B = oper can /unkline users from server
-# n = oper can send local server notices(/notice $servername message)
-# N = oper can send global notices(/notice $*.dal.net message)
-# A = can set umode +Aa to display server admin access in /whois
-# a = can set umode +a to display services admin access in /whois
-# u = oper can set /umode +c
-# f = oper can set /umode +f
-# s = oper can send /chatops
-# o = local oper, flags included: rhgwlckbBnuf
-# O = global oper, flags included: oCKNs
-#
-# Note: the RD flags must be manually included if you wish the
-# O:line to give /restart or /die access. They do not appear in
-# any wildcard lines, therefore a full set of operflags is OaARD
-#
-# This is a plain vanilla O:line:
-O:*.toledolink.com:nopassword:Russell:*:10
-#
-# and this line forces ident:
-O:rmiller@glass.toledolink.com:nopassword:Russell::10
-#
-# This line is a generic "local operator", because of the flags, the only
-# thing that really makes them global operators, is if they have the flags
-# CKN set in their access flags.
-#
-# this line permits the nickname "jhs" with the password of "ITBites" to
-# be a local operator only (be able to issue commands locally -- can /kill
-# and /squit and /connect -- but *only* locally)
-#
-O:*.something.net:ITBites:jhs:o:10
-#
-# a crypted password line (NOTE that if you have crypted passwords, *all*
-# of you passwords must be crypted! In fact, if you are getting an error
-# "Incorrect Password" it may well be because crypted passwords are
-# defined and you have used plaintext. So my example of plaintext and
-# crypted strings in the same IRC server configuration file is an
-# impossibility (but it is just theoretical, which is why I explained both).
-#
-O:rmiller@*.toledolink.com:T0eiVgHrqeKTQ:Russell::10
-#
-# U: [OPTIONAL]. This line defines the servers that IRC recognizes as being
-# allowed to make various changes to the IRC environment (mode changes, for
-# example), without complaining or otherwise obstructing them. For example,
-# DALnet requires the following line:
-U:services.dal.net:*:*
-#
-# X: [SUGGESTED]. This line defines the password that an operator must use
-# to restart or die the server. Note that they must also have the R and D
-# operflags in their O:line. This is just a security precaution against
-# accidentally typing /die or /restart.
-#
-# X:<password for /DIE>:<password for /RESTART>
-X:diepass:restartpass
-# C: [NETWORKED]. These lines define what servers your server tries to
-# connect to.
-# N: [NETWORKED]. These lines define what servers your server permits
-# connections to be initiated from.
-# C/N lines MUST be used in pairs. You cannot have one without the other.
-#
-# C: lines contain the following fields:
-# C:remote server's hostname:passwd:remote server's name:port:conn class
-# (connection class):source ip
-# N: lines contain the following fields:
-# N:remote server's hostname:passwd:remote server's name:host mask:encryption
-# and/or compresion support:conn class
-#
-# "host mask" is the number of parts in *your* hostname to mask to. For
-# instance, with my servername being "csa.bu.edu", if I wanted to present
-# my servername to be "*.bu.edu" I would have a host-mask portion of "1".
-#
-# it is *strongly* advised that your C/N line passwords be different for
-# security's sake.
-#
-# ident is allowed in the server's hostname part of the field.
-# these lines tell the server to automatically (note the port number, that
-# means automatic connection) connect to mindijari.ca.us.dal.net:
-#
-C:dalvenjah@nowhere.he.us.dal.net:bigspark:nowhere.he.us.dal.net:7000:32
-N:dalvenjah@nowhere.he.us.dal.net:bigalpha:nowhere.he.us.dal.net::32
-#
-# This server's connection lines are more vanilla, masking the host to
-# *.toledolink.com (as described above):
-#
-C:*.dalnet.com:camelsrk00l:*.dalnet.com::32
-N:*.dalnet.com:andsoarellamas:*.dalnet.com:1:32
-#
-# This example displays the use of RC4 streaming encryption, denoted by the "E"
-# in the N: line. This MUST be matched on the remote server's N: line.
-#
-C:192.168.0.5:milk42cows:server.dal.net::32
-N:192.168.0.5:milk42cows:server.dal.net:E:32
-#
-# This example displays the use of zlib-compression for outgoing data.
-# It's generally a good idea to compress hub<->hub and hub->leaf, but
-# compressing leaf->hub is discouraged on large client servers due to
-# higher CPU usage.
-#
-C:172.16.12.3:milk42cows:server.dal.net::32
-N:172.16.12.3:milk42cows:server.dal.net:Z:32
-#
-# Here's an example using both compression and encryption.
-#
-C:10.182.3.2:milk42cows:server.dal.net::32
-N:10.182.3.2:milk42cows:server.dal.net:EZ:32
-#
-# In this example, the source ip is set to 192.168.10.200 when /connecting
-# out to another server. This is useful for servers which don't want to use
-# the main IP in the M: as the server<->server IP. Theoretically, you could
-# bind to a different ip for each server that you connect to.
-#
-C:192.168.2.1:milk42cows:server.dal.net::32:192.168.10.200
-N:192.168.2.1:milk42cows:server.dal.net::32
-#
-# K: [OBSOLETE]. Bans are now stored in the kline.conf file.
-#
-# These lines define user@host patterns to be banned from
-# this particular server (with an optional time field). Note that K: lines
-# are *not* global, and if you ban a user they can still use any other IRC
-# server (unless they have specifically been banned there as well).
-#
-# The time field (same as reason) is only used if you #define
-# TIMED_KLINES in config.h, and even then they are discouraged.
-#
-# the fields are defined as:
-# K:hostmask:reason:username
-# wildcards are permitted in any one of the fields, in other words, you can
-# K:*::* if you wanted (but your server wouldn't be used much ;-)
-#
-# Spaces are permitted in the reason field (you don't have to use _).
-# The /stats command has been modified to replace all spaces with _'s when
-# doing a /stats k.
-#
-# This K: line bans the username "hrose" (the wildcards are used to make
-# sure that any ident-checking character will match) on any machine from
-# the University of Boston.
-K:*.bu.edu:Hacking #dragonrealm:*hrose*
-#
-# This K: line bans any users from acs*.bu.edu between the hours of 8am
-# and 12pm and 1pm and 5pm (the time is always the server's local time).
-# Time-based K-lines such as this require TIMED_KLINES in config.h to be
-# #defined.
-K:acs*.bu.edu:0800-1200,1300-1700:*
-# Note that 24 hour time is used (no "AM" or "PM").
-#
-# q: [DISCOURAGED]. These lines "quarantine" specified servers. Because
-# of the way they operates, the same q: lines MUST be installed by
-# everyone or the net will keep breaking. I CANNOT EMPHASIZE THIS ENOUGH.
-# Do NOT use q: lines lightly!
-#
-# This is NOT a nick q-line, if you wish to quarantine a NICK, see below.
-#
-# The fields are as follows:
-# q:*:reason why quarantine is in place:servername
-#
-q::this server is too slow and lags the net:cm5.eng.umd.edu
-#
-# Q: [OPTIONAL]. Different from the above type of q: line, these lines
-# prevent users on your server from picking certain nicks. This is useful
-# if your network has 'reserved' nicknames that should not be taken by
-# normal users. Note the difference in capitalization and BE CAREFUL!
-#
-# The fields are as follows:
-# Q:*:reason why quarantine is in place:nickname
-#
-# For example, DALnet servers MUST have the following lines at minimum:
-Q::Reserved for services:ChanServ
-Q::Reserved for services:NickServ
-Q::Reserved for services:MemoServ
-Q::Reserved for services:OperServ
-Q::Reserved for services:HelpServ
-#
-Q::Reserved for operators:DALnet
-Q::Reserved for operators:IRCop
-#
-#
-# Z: [DISCOURAGED]. These block ALL incoming connections from a certain
-# IP address mask. They can stop users who log on and issue the SERVER
-# command a couple of times just to annoy IRC operators. They are more
-# powerful than K-lines because they can stop users before they've had a
-# chance to register. This works on servers, SO BE VERY CAREFUL WITH
-# YOUR Z-LINE MASKS. Z-lines are a LAST RESORT. They are much too
-# dangerous and powerful to be using them instead of K-lines and akills.
-#
-# NOTE 1: Z-lines do NOT work on host names! Only IP addresses.
-# NOTE 2: Z-lines are part of /stats k.
-# NOTE 3: The :* at the end is REQUIRED. Not using it will cause both
-# ircd and chkconf to segfault without saying why.
-#
-# Syntax:
-# Z:IP mask:reason for zapping:*
-Z:127.0.0.1:Please don't log on from the local machine:*
-#
-# H: [OPTIONAL]. These lines define who you permit to act as a "hub" to
-# you (that is, who you permit to connect non-leafed servers to you).
-#
-# the first field may use wildcards, the third field *must* be an exact
-# match for a server's name (NOT a server's hostname, if they differ, the
-# server's name must be used). If the servername is a wildcard (e.g. *.au)
-# that is an acceptable name for the third field.
-#
-# The fields are as follows:
-# H:servers which are permitted entry::hub server
-#
-# Example, permit nowhere.ca.us.dal.net to allow any servers behind it to
-# connect:
-H:*::nowhere.he.us.dal.net
-#
-# Example, permit irc-2.mit.edu to allow any MIT servers behind it to
-# connect:
-H:*.mit.edu::irc-2.mit.edu
-#
-# P : [SUGGESTED]
-# port. The port line allows the server to listen on various ports for
-# connections. Fields in order: address mask to allow connections from,
-# address to bind to, unused, port to listen on
-#
-P:*:192.168.0.4::6665
-P:128.32.*:::6665
-P::209.42.128.252::31337
-#
-# Listen on port 6665 on all available interfaces. Only allow connections from
-# net 128.32. This is checked before existance of other access is available.
-# 128.32.* == 128.32.0.0 where 0 is a wildcard.
-# Also listen to port 31337 on only 209.42.128.252. Allow connections from
-# anywhere.
-#
-# E : [OPTIONAL]
-# Exception lines.
-# Bypasses K: lines for matching clients. First arg is hostmask,
-# Second arg is unused. Third arg is optional username
-# Every Oper on a server should have one of these.
-#
-E:shell3.ba.best.com::jrsE:*.concentric.net::*

-<br><a name="SEC1" href="#TOC1">PCRE REGULAR EXPRESSION DETAILS</a><br>
-<P>
-The syntax and semantics of the regular expressions supported by PCRE are
-described below. Regular expressions are also described in the Perl
-documentation and in a number of other books, some of which have copious
-examples. Jeffrey Friedl's "Mastering Regular Expressions", published by
-O'Reilly, covers them in great detail. The description here is intended as
-reference documentation.
-</P>
-<P>
-The basic operation of PCRE is on strings of bytes. However, there is also
-support for UTF-8 character strings. To use this support you must build PCRE to
-include UTF-8 support, and then call <b>pcre_compile()</b> with the PCRE_UTF8
-option. How this affects the pattern matching is mentioned in several places
-below. There is also a summary of UTF-8 features in the
-<a href="pcre.html#utf8support">section on UTF-8 support</a>
-in the main
-<a href="pcre.html"><b>pcre</b></a>
-page.
-</P>
-<P>
-A regular expression is a pattern that is matched against a subject string from
-left to right. Most characters stand for themselves in a pattern, and match the
-corresponding characters in the subject. As a trivial example, the pattern
-</P>
-<P>
-<pre>
- The quick brown fox
-</PRE>
-</P>
-<P>
-matches a portion of a subject string that is identical to itself. The power of
-regular expressions comes from the ability to include alternatives and
-repetitions in the pattern. These are encoded in the pattern by the use of
-<i>meta-characters</i>, which do not stand for themselves but instead are
-interpreted in some special way.
-</P>
-<P>
-There are two different sets of meta-characters: those that are recognized
-anywhere in the pattern except within square brackets, and those that are
-recognized in square brackets. Outside square brackets, the meta-characters are
-as follows:
-</P>
-<P>
-<pre>
- \ general escape character with several uses
- ^ assert start of string (or line, in multiline mode)
- $ assert end of string (or line, in multiline mode)
- . match any character except newline (by default)
- [ start character class definition
- | start of alternative branch
- ( start subpattern
- ) end subpattern
- ? extends the meaning of (
- also 0 or 1 quantifier
- also quantifier minimizer
- * 0 or more quantifier
- + 1 or more quantifier
- also "possessive quantifier"
- { start min/max quantifier
-</PRE>
-</P>
-<P>
-Part of a pattern that is in square brackets is called a "character class". In
-a character class the only meta-characters are:
-</P>
-<P>
-<pre>
- \ general escape character
- ^ negate the class, but only if the first character
- - indicates character range
- [ POSIX character class (only if followed by POSIX
- syntax)
- ] terminates the character class
-</PRE>
-</P>
-<P>
-The following sections describe the use of each of the meta-characters.
-</P>
-<br><a name="SEC2" href="#TOC1">BACKSLASH</a><br>
-<P>
-The backslash character has several uses. Firstly, if it is followed by a
-non-alphameric character, it takes away any special meaning that character may
-have. This use of backslash as an escape character applies both inside and
-outside character classes.
-</P>
-<P>
-For example, if you want to match a * character, you write \* in the pattern.
-This escaping action applies whether or not the following character would
-otherwise be interpreted as a meta-character, so it is always safe to precede a
-non-alphameric with backslash to specify that it stands for itself. In
-particular, if you want to match a backslash, you write \\.
-</P>
-<P>
-If a pattern is compiled with the PCRE_EXTENDED option, whitespace in the
-pattern (other than in a character class) and characters between a # outside
-a character class and the next newline character are ignored. An escaping
-backslash can be used to include a whitespace or # character as part of the
-pattern.
-</P>
-<P>
-If you want to remove the special meaning from a sequence of characters, you
-can do so by putting them between \Q and \E. This is different from Perl in
-that $ and @ are handled as literals in \Q...\E sequences in PCRE, whereas in
-Perl, $ and @ cause variable interpolation. Note the following examples:
-</P>
-<P>
-<pre>
- Pattern PCRE matches Perl matches
-</PRE>
-</P>
-<P>
-<pre>
- \Qabc$xyz\E abc$xyz abc followed by the
- contents of $xyz
- \Qabc\$xyz\E abc\$xyz abc\$xyz
- \Qabc\E\$\Qxyz\E abc$xyz abc$xyz
-</PRE>
-</P>
-<P>
-The \Q...\E sequence is recognized both inside and outside character classes.
-</P>
-<P>
-A second use of backslash provides a way of encoding non-printing characters
-in patterns in a visible manner. There is no restriction on the appearance of
-non-printing characters, apart from the binary zero that terminates a pattern,
-but when a pattern is being prepared by text editing, it is usually easier to
-use one of the following escape sequences than the binary character it
-represents:
-</P>
-<P>
-<pre>
- \a alarm, that is, the BEL character (hex 07)
- \cx "control-x", where x is any character
- \e escape (hex 1B)
- \f formfeed (hex 0C)
- \n newline (hex 0A)
- \r carriage return (hex 0D)
- \t tab (hex 09)
- \ddd character with octal code ddd, or backreference
- \xhh character with hex code hh
- \x{hhh..} character with hex code hhh... (UTF-8 mode only)
-</PRE>
-</P>
-<P>
-The precise effect of \cx is as follows: if x is a lower case letter, it
-is converted to upper case. Then bit 6 of the character (hex 40) is inverted.
-Thus \cz becomes hex 1A, but \c{ becomes hex 3B, while \c; becomes hex
-7B.
-</P>
-<P>
-After \x, from zero to two hexadecimal digits are read (letters can be in
-upper or lower case). In UTF-8 mode, any number of hexadecimal digits may
-appear between \x{ and }, but the value of the character code must be less
-than 2**31 (that is, the maximum hexadecimal value is 7FFFFFFF). If characters
-other than hexadecimal digits appear between \x{ and }, or if there is no
-terminating }, this form of escape is not recognized. Instead, the initial
-\x will be interpreted as a basic hexadecimal escape, with no following
-digits, giving a byte whose value is zero.
-</P>
-<P>
-Characters whose value is less than 256 can be defined by either of the two
-syntaxes for \x when PCRE is in UTF-8 mode. There is no difference in the
-way they are handled. For example, \xdc is exactly the same as \x{dc}.
-</P>
-<P>
-After \0 up to two further octal digits are read. In both cases, if there
-are fewer than two digits, just those that are present are used. Thus the
-sequence \0\x\07 specifies two binary zeros followed by a BEL character
-(code value 7). Make sure you supply two digits after the initial zero if the
-character that follows is itself an octal digit.
-</P>
-<P>
-The handling of a backslash followed by a digit other than 0 is complicated.
-Outside a character class, PCRE reads it and any following digits as a decimal
-number. If the number is less than 10, or if there have been at least that many
-previous capturing left parentheses in the expression, the entire sequence is
-taken as a <i>back reference</i>. A description of how this works is given
-later, following the discussion of parenthesized subpatterns.
-</P>
-<P>
-Inside a character class, or if the decimal number is greater than 9 and there
-have not been that many capturing subpatterns, PCRE re-reads up to three octal
-digits following the backslash, and generates a single byte from the least
-significant 8 bits of the value. Any subsequent digits stand for themselves.
-For example:
-</P>
-<P>
-<pre>
- \040 is another way of writing a space
- \40 is the same, provided there are fewer than 40
- previous capturing subpatterns
- \7 is always a back reference
- \11 might be a back reference, or another way of
- writing a tab
- \011 is always a tab
- \0113 is a tab followed by the character "3"
- \113 might be a back reference, otherwise the
- character with octal code 113
- \377 might be a back reference, otherwise
- the byte consisting entirely of 1 bits
- \81 is either a back reference, or a binary zero
- followed by the two characters "8" and "1"
-</PRE>
-</P>
-<P>
-Note that octal values of 100 or greater must not be introduced by a leading
-zero, because no more than three octal digits are ever read.
-</P>
-<P>
-All the sequences that define a single byte value or a single UTF-8 character
-(in UTF-8 mode) can be used both inside and outside character classes. In
-addition, inside a character class, the sequence \b is interpreted as the
-backspace character (hex 08). Outside a character class it has a different
-meaning (see below).
-</P>
-<P>
-The third use of backslash is for specifying generic character types:
-</P>
-<P>
-<pre>
- \d any decimal digit
- \D any character that is not a decimal digit
- \s any whitespace character
- \S any character that is not a whitespace character
- \w any "word" character
- \W any "non-word" character
-</PRE>
-</P>
-<P>
-Each pair of escape sequences partitions the complete set of characters into
-two disjoint sets. Any given character matches one, and only one, of each pair.
-</P>
-<P>
-In UTF-8 mode, characters with values greater than 255 never match \d, \s, or
-\w, and always match \D, \S, and \W.
-</P>
-<P>
-For compatibility with Perl, \s does not match the VT character (code 11).
-This makes it different from the the POSIX "space" class. The \s characters
-are HT (9), LF (10), FF (12), CR (13), and space (32).
-</P>
-<P>
-A "word" character is any letter or digit or the underscore character, that is,
-any character which can be part of a Perl "word". The definition of letters and
-digits is controlled by PCRE's character tables, and may vary if locale-
-specific matching is taking place (see
-<a href="pcreapi.html#localesupport">"Locale support"</a>
-in the
-<a href="pcreapi.html"><b>pcreapi</b></a>
-page). For example, in the "fr" (French) locale, some character codes greater
-than 128 are used for accented letters, and these are matched by \w.
-</P>
-<P>
-These character type sequences can appear both inside and outside character
-classes. They each match one character of the appropriate type. If the current
-matching point is at the end of the subject string, all of them fail, since
-there is no character to match.
-</P>
-<P>
-The fourth use of backslash is for certain simple assertions. An assertion
-specifies a condition that has to be met at a particular point in a match,
-without consuming any characters from the subject string. The use of
-subpatterns for more complicated assertions is described below. The backslashed
-assertions are
-</P>
-<P>
-<pre>
- \b matches at a word boundary
- \B matches when not at a word boundary
- \A matches at start of subject
- \Z matches at end of subject or before newline at end
- \z matches at end of subject
- \G matches at first matching position in subject
-</PRE>
-</P>
-<P>
-These assertions may not appear in character classes (but note that \b has a
-different meaning, namely the backspace character, inside a character class).
-</P>
-<P>
-A word boundary is a position in the subject string where the current character
-and the previous character do not both match \w or \W (i.e. one matches
-\w and the other matches \W), or the start or end of the string if the
-first or last character matches \w, respectively.
-</P>
-<P>
-The \A, \Z, and \z assertions differ from the traditional circumflex and
-dollar (described below) in that they only ever match at the very start and end
-of the subject string, whatever options are set. Thus, they are independent of
-multiline mode.
-</P>
-<P>
-They are not affected by the PCRE_NOTBOL or PCRE_NOTEOL options. If the
-<i>startoffset</i> argument of <b>pcre_exec()</b> is non-zero, indicating that
-matching is to start at a point other than the beginning of the subject, \A
-can never match. The difference between \Z and \z is that \Z matches before
-a newline that is the last character of the string as well as at the end of the
-string, whereas \z matches only at the end.
-</P>
-<P>
-The \G assertion is true only when the current matching position is at the
-start point of the match, as specified by the <i>startoffset</i> argument of
-<b>pcre_exec()</b>. It differs from \A when the value of <i>startoffset</i> is
-non-zero. By calling <b>pcre_exec()</b> multiple times with appropriate
-arguments, you can mimic Perl's /g option, and it is in this kind of
-implementation where \G can be useful.
-</P>
-<P>
-Note, however, that PCRE's interpretation of \G, as the start of the current
-match, is subtly different from Perl's, which defines it as the end of the
-previous match. In Perl, these can be different when the previously matched
-string was empty. Because PCRE does just one match at a time, it cannot
-reproduce this behaviour.
-</P>
-<P>
-If all the alternatives of a pattern begin with \G, the expression is anchored
-to the starting match position, and the "anchored" flag is set in the compiled
-regular expression.
-</P>
-<br><a name="SEC3" href="#TOC1">CIRCUMFLEX AND DOLLAR</a><br>
-<P>
-Outside a character class, in the default matching mode, the circumflex
-character is an assertion which is true only if the current matching point is
-at the start of the subject string. If the <i>startoffset</i> argument of
-<b>pcre_exec()</b> is non-zero, circumflex can never match if the PCRE_MULTILINE
-option is unset. Inside a character class, circumflex has an entirely different
-meaning (see below).
-</P>
-<P>
-Circumflex need not be the first character of the pattern if a number of
-alternatives are involved, but it should be the first thing in each alternative
-in which it appears if the pattern is ever to match that branch. If all
-possible alternatives start with a circumflex, that is, if the pattern is
-constrained to match only at the start of the subject, it is said to be an
-"anchored" pattern. (There are also other constructs that can cause a pattern
-to be anchored.)
-</P>
-<P>
-A dollar character is an assertion which is true only if the current matching
-point is at the end of the subject string, or immediately before a newline
-character that is the last character in the string (by default). Dollar need
-not be the last character of the pattern if a number of alternatives are
-involved, but it should be the last item in any branch in which it appears.
-Dollar has no special meaning in a character class.
-</P>
-<P>
-The meaning of dollar can be changed so that it matches only at the very end of
-the string, by setting the PCRE_DOLLAR_ENDONLY option at compile time. This
-does not affect the \Z assertion.
-</P>
-<P>
-The meanings of the circumflex and dollar characters are changed if the
-PCRE_MULTILINE option is set. When this is the case, they match immediately
-after and immediately before an internal newline character, respectively, in
-addition to matching at the start and end of the subject string. For example,
-the pattern /^abc$/ matches the subject string "def\nabc" in multiline mode,
-but not otherwise. Consequently, patterns that are anchored in single line mode
-because all branches start with ^ are not anchored in multiline mode, and a
-match for circumflex is possible when the <i>startoffset</i> argument of
-<b>pcre_exec()</b> is non-zero. The PCRE_DOLLAR_ENDONLY option is ignored if
-PCRE_MULTILINE is set.
-</P>
-<P>
-Note that the sequences \A, \Z, and \z can be used to match the start and
-end of the subject in both modes, and if all branches of a pattern start with
-\A it is always anchored, whether PCRE_MULTILINE is set or not.
-</P>
-<br><a name="SEC4" href="#TOC1">FULL STOP (PERIOD, DOT)</a><br>
-<P>
-Outside a character class, a dot in the pattern matches any one character in
-the subject, including a non-printing character, but not (by default) newline.
-In UTF-8 mode, a dot matches any UTF-8 character, which might be more than one
-byte long, except (by default) for newline. If the PCRE_DOTALL option is set,
-dots match newlines as well. The handling of dot is entirely independent of the
-handling of circumflex and dollar, the only relationship being that they both
-involve newline characters. Dot has no special meaning in a character class.
-</P>
-<br><a name="SEC5" href="#TOC1">MATCHING A SINGLE BYTE</a><br>
-<P>
-Outside a character class, the escape sequence \C matches any one byte, both
-in and out of UTF-8 mode. Unlike a dot, it always matches a newline. The
-feature is provided in Perl in order to match individual bytes in UTF-8 mode.
-Because it breaks up UTF-8 characters into individual bytes, what remains in
-the string may be a malformed UTF-8 string. For this reason it is best avoided.
-</P>
-<P>
-PCRE does not allow \C to appear in lookbehind assertions (see below), because
-in UTF-8 mode it makes it impossible to calculate the length of the lookbehind.
-</P>
-<br><a name="SEC6" href="#TOC1">SQUARE BRACKETS</a><br>
-<P>
-An opening square bracket introduces a character class, terminated by a closing
-square bracket. A closing square bracket on its own is not special. If a
-closing square bracket is required as a member of the class, it should be the
-first data character in the class (after an initial circumflex, if present) or
-escaped with a backslash.
-</P>
-<P>
-A character class matches a single character in the subject. In UTF-8 mode, the
-character may occupy more than one byte. A matched character must be in the set
-of characters defined by the class, unless the first character in the class
-definition is a circumflex, in which case the subject character must not be in
-the set defined by the class. If a circumflex is actually required as a member
-of the class, ensure it is not the first character, or escape it with a
-backslash.
-</P>
-<P>
-For example, the character class [aeiou] matches any lower case vowel, while
-[^aeiou] matches any character that is not a lower case vowel. Note that a
-circumflex is just a convenient notation for specifying the characters which
-are in the class by enumerating those that are not. It is not an assertion: it
-still consumes a character from the subject string, and fails if the current
-pointer is at the end of the string.
-</P>
-<P>
-In UTF-8 mode, characters with values greater than 255 can be included in a
-class as a literal string of bytes, or by using the \x{ escaping mechanism.
-</P>
-<P>
-When caseless matching is set, any letters in a class represent both their
-upper case and lower case versions, so for example, a caseless [aeiou] matches
-"A" as well as "a", and a caseless [^aeiou] does not match "A", whereas a
-caseful version would. PCRE does not support the concept of case for characters
-with values greater than 255.
-</P>
-<P>
-The newline character is never treated in any special way in character classes,
-whatever the setting of the PCRE_DOTALL or PCRE_MULTILINE options is. A class
-such as [^a] will always match a newline.
-</P>
-<P>
-The minus (hyphen) character can be used to specify a range of characters in a
-character class. For example, [d-m] matches any letter between d and m,
-inclusive. If a minus character is required in a class, it must be escaped with
-a backslash or appear in a position where it cannot be interpreted as
-indicating a range, typically as the first or last character in the class.
-</P>
-<P>
-It is not possible to have the literal character "]" as the end character of a
-range. A pattern such as [W-]46] is interpreted as a class of two characters
-("W" and "-") followed by a literal string "46]", so it would match "W46]" or
-"-46]". However, if the "]" is escaped with a backslash it is interpreted as
-the end of range, so [W-\]46] is interpreted as a single class containing a
-range followed by two separate characters. The octal or hexadecimal
-representation of "]" can also be used to end a range.
-</P>
-<P>
-Ranges operate in the collating sequence of character values. They can also be
-used for characters specified numerically, for example [\000-\037]. In UTF-8
-mode, ranges can include characters whose values are greater than 255, for
-example [\x{100}-\x{2ff}].
-</P>
-<P>
-If a range that includes letters is used when caseless matching is set, it
-matches the letters in either case. For example, [W-c] is equivalent to
-[][\^_`wxyzabc], matched caselessly, and if character tables for the "fr"
-locale are in use, [\xc8-\xcb] matches accented E characters in both cases.
-</P>
-<P>
-The character types \d, \D, \s, \S, \w, and \W may also appear in a
-character class, and add the characters that they match to the class. For
-example, [\dABCDEF] matches any hexadecimal digit. A circumflex can
-conveniently be used with the upper case character types to specify a more
-restricted set of characters than the matching lower case type. For example,
-the class [^\W_] matches any letter or digit, but not underscore.
-</P>
-<P>
-All non-alphameric characters other than \, -, ^ (at the start) and the
-terminating ] are non-special in character classes, but it does no harm if they
-are escaped.
-</P>
-<br><a name="SEC7" href="#TOC1">POSIX CHARACTER CLASSES</a><br>
-<P>
-Perl supports the POSIX notation for character classes, which uses names
-enclosed by [: and :] within the enclosing square brackets. PCRE also supports
-this notation. For example,
-</P>
-<P>
-<pre>
- [01[:alpha:]%]
-</PRE>
-</P>
-<P>
-matches "0", "1", any alphabetic character, or "%". The supported class names
-are
-</P>
-<P>
-<pre>
- alnum letters and digits
- alpha letters
- ascii character codes 0 - 127
- blank space or tab only
- cntrl control characters
- digit decimal digits (same as \d)
- graph printing characters, excluding space
- lower lower case letters
- print printing characters, including space
- punct printing characters, excluding letters and digits
- space white space (not quite the same as \s)
- upper upper case letters
- word "word" characters (same as \w)
- xdigit hexadecimal digits
-</PRE>
-</P>
-<P>
-The "space" characters are HT (9), LF (10), VT (11), FF (12), CR (13), and
-space (32). Notice that this list includes the VT character (code 11). This
-makes "space" different to \s, which does not include VT (for Perl
-compatibility).
-</P>
-<P>
-The name "word" is a Perl extension, and "blank" is a GNU extension from Perl
-5.8. Another Perl extension is negation, which is indicated by a ^ character
-after the colon. For example,
-</P>
-<P>
-<pre>
- [12[:^digit:]]
-</PRE>
-</P>
-<P>
-matches "1", "2", or any non-digit. PCRE (and Perl) also recognize the POSIX
-syntax [.ch.] and [=ch=] where "ch" is a "collating element", but these are not
-supported, and an error is given if they are encountered.
-</P>
-<P>
-In UTF-8 mode, characters with values greater than 255 do not match any of
-the POSIX character classes.
-</P>
-<br><a name="SEC8" href="#TOC1">VERTICAL BAR</a><br>
-<P>
-Vertical bar characters are used to separate alternative patterns. For example,
-the pattern
-</P>
-<P>
-<pre>
- gilbert|sullivan
-</PRE>
-</P>
-<P>
-matches either "gilbert" or "sullivan". Any number of alternatives may appear,
-and an empty alternative is permitted (matching the empty string).
-The matching process tries each alternative in turn, from left to right,
-and the first one that succeeds is used. If the alternatives are within a
-subpattern (defined below), "succeeds" means matching the rest of the main
-pattern as well as the alternative in the subpattern.
-</P>
-<br><a name="SEC9" href="#TOC1">INTERNAL OPTION SETTING</a><br>
-<P>
-The settings of the PCRE_CASELESS, PCRE_MULTILINE, PCRE_DOTALL, and
-PCRE_EXTENDED options can be changed from within the pattern by a sequence of
-Perl option letters enclosed between "(?" and ")". The option letters are
-</P>
-<P>
-<pre>
- i for PCRE_CASELESS
- m for PCRE_MULTILINE
- s for PCRE_DOTALL
- x for PCRE_EXTENDED
-</PRE>
-</P>
-<P>
-For example, (?im) sets caseless, multiline matching. It is also possible to
-unset these options by preceding the letter with a hyphen, and a combined
-setting and unsetting such as (?im-sx), which sets PCRE_CASELESS and
-PCRE_MULTILINE while unsetting PCRE_DOTALL and PCRE_EXTENDED, is also
-permitted. If a letter appears both before and after the hyphen, the option is
-unset.
-</P>
-<P>
-When an option change occurs at top level (that is, not inside subpattern
-parentheses), the change applies to the remainder of the pattern that follows.
-If the change is placed right at the start of a pattern, PCRE extracts it into
-the global options (and it will therefore show up in data extracted by the
-<b>pcre_fullinfo()</b> function).
-</P>
-<P>
-An option change within a subpattern affects only that part of the current
-pattern that follows it, so
-</P>
-<P>
-<pre>
- (a(?i)b)c
-</PRE>
-</P>
-<P>
-matches abc and aBc and no other strings (assuming PCRE_CASELESS is not used).
-By this means, options can be made to have different settings in different
-parts of the pattern. Any changes made in one alternative do carry on
-into subsequent branches within the same subpattern. For example,
-</P>
-<P>
-<pre>
- (a(?i)b|c)
-</PRE>
-</P>
-<P>
-matches "ab", "aB", "c", and "C", even though when matching "C" the first
-branch is abandoned before the option setting. This is because the effects of
-option settings happen at compile time. There would be some very weird
-behaviour otherwise.
-</P>
-<P>
-The PCRE-specific options PCRE_UNGREEDY and PCRE_EXTRA can be changed in the
-same way as the Perl-compatible options by using the characters U and X
-respectively. The (?X) flag setting is special in that it must always occur
-earlier in the pattern than any of the additional features it turns on, even
-when it is at top level. It is best put at the start.
-</P>
-<br><a name="SEC10" href="#TOC1">SUBPATTERNS</a><br>
-<P>
-Subpatterns are delimited by parentheses (round brackets), which can be nested.
-Marking part of a pattern as a subpattern does two things:
-</P>
-<P>
-1. It localizes a set of alternatives. For example, the pattern
-</P>
-<P>
-<pre>
- cat(aract|erpillar|)
-</PRE>
-</P>
-<P>
-matches one of the words "cat", "cataract", or "caterpillar". Without the
-parentheses, it would match "cataract", "erpillar" or the empty string.
-</P>
-<P>
-2. It sets up the subpattern as a capturing subpattern (as defined above).
-When the whole pattern matches, that portion of the subject string that matched
-the subpattern is passed back to the caller via the <i>ovector</i> argument of
-<b>pcre_exec()</b>. Opening parentheses are counted from left to right (starting
-from 1) to obtain the numbers of the capturing subpatterns.
-</P>
-<P>
-For example, if the string "the red king" is matched against the pattern
-</P>
-<P>
-<pre>
- the ((red|white) (king|queen))
-</PRE>
-</P>
-<P>
-the captured substrings are "red king", "red", and "king", and are numbered 1,
-2, and 3, respectively.
-</P>
-<P>
-The fact that plain parentheses fulfil two functions is not always helpful.
-There are often times when a grouping subpattern is required without a
-capturing requirement. If an opening parenthesis is followed by a question mark
-and a colon, the subpattern does not do any capturing, and is not counted when
-computing the number of any subsequent capturing subpatterns. For example, if
-the string "the white queen" is matched against the pattern
-</P>
-<P>
-<pre>
- the ((?:red|white) (king|queen))
-</PRE>
-</P>
-<P>
-the captured substrings are "white queen" and "queen", and are numbered 1 and
-2. The maximum number of capturing subpatterns is 65535, and the maximum depth
-of nesting of all subpatterns, both capturing and non-capturing, is 200.
-</P>
-<P>
-As a convenient shorthand, if any option settings are required at the start of
-a non-capturing subpattern, the option letters may appear between the "?" and
-the ":". Thus the two patterns
-</P>
-<P>
-<pre>
- (?i:saturday|sunday)
- (?:(?i)saturday|sunday)
-</PRE>
-</P>
-<P>
-match exactly the same set of strings. Because alternative branches are tried
-from left to right, and options are not reset until the end of the subpattern
-is reached, an option setting in one branch does affect subsequent branches, so
-the above patterns match "SUNDAY" as well as "Saturday".
-</P>
-<br><a name="SEC11" href="#TOC1">NAMED SUBPATTERNS</a><br>
-<P>
-Identifying capturing parentheses by number is simple, but it can be very hard
-to keep track of the numbers in complicated regular expressions. Furthermore,
-if an expression is modified, the numbers may change. To help with the
-difficulty, PCRE supports the naming of subpatterns, something that Perl does
-not provide. The Python syntax (?P<name>...) is used. Names consist of
-alphanumeric characters and underscores, and must be unique within a pattern.
-</P>
-<P>
-Named capturing parentheses are still allocated numbers as well as names. The
-PCRE API provides function calls for extracting the name-to-number translation
-table from a compiled pattern. For further details see the
-<a href="pcreapi.html"><b>pcreapi</b></a>
-documentation.
-</P>
-<br><a name="SEC12" href="#TOC1">REPETITION</a><br>
-<P>
-Repetition is specified by quantifiers, which can follow any of the following
-items:
-</P>
-<P>
-<pre>
- a literal data character
- the . metacharacter
- the \C escape sequence
- escapes such as \d that match single characters
- a character class
- a back reference (see next section)
- a parenthesized subpattern (unless it is an assertion)
-</PRE>
-</P>
-<P>
-The general repetition quantifier specifies a minimum and maximum number of
-permitted matches, by giving the two numbers in curly brackets (braces),
-separated by a comma. The numbers must be less than 65536, and the first must
-be less than or equal to the second. For example:
-</P>
-<P>
-<pre>
- z{2,4}
-</PRE>
-</P>
-<P>
-matches "zz", "zzz", or "zzzz". A closing brace on its own is not a special
-character. If the second number is omitted, but the comma is present, there is
-no upper limit; if the second number and the comma are both omitted, the
-quantifier specifies an exact number of required matches. Thus
-</P>
-<P>
-<pre>
- [aeiou]{3,}
-</PRE>
-</P>
-<P>
-matches at least 3 successive vowels, but may match many more, while
-</P>
-<P>
-<pre>
- \d{8}
-</PRE>
-</P>
-<P>
-matches exactly 8 digits. An opening curly bracket that appears in a position
-where a quantifier is not allowed, or one that does not match the syntax of a
-quantifier, is taken as a literal character. For example, {,6} is not a
-quantifier, but a literal string of four characters.
-</P>
-<P>
-In UTF-8 mode, quantifiers apply to UTF-8 characters rather than to individual
-bytes. Thus, for example, \x{100}{2} matches two UTF-8 characters, each of
-which is represented by a two-byte sequence.
-</P>
-<P>
-The quantifier {0} is permitted, causing the expression to behave as if the
-previous item and the quantifier were not present.
-</P>
-<P>
-For convenience (and historical compatibility) the three most common
-quantifiers have single-character abbreviations:
-</P>
-<P>
-<pre>
- * is equivalent to {0,}
- + is equivalent to {1,}
- ? is equivalent to {0,1}
-</PRE>
-</P>
-<P>
-It is possible to construct infinite loops by following a subpattern that can
-match no characters with a quantifier that has no upper limit, for example:
-</P>
-<P>
-<pre>
- (a?)*
-</PRE>
-</P>
-<P>
-Earlier versions of Perl and PCRE used to give an error at compile time for
-such patterns. However, because there are cases where this can be useful, such
-patterns are now accepted, but if any repetition of the subpattern does in fact
-match no characters, the loop is forcibly broken.
-</P>
-<P>
-By default, the quantifiers are "greedy", that is, they match as much as
-possible (up to the maximum number of permitted times), without causing the
-rest of the pattern to fail. The classic example of where this gives problems
-is in trying to match comments in C programs. These appear between the
-sequences /* and */ and within the sequence, individual * and / characters may
-appear. An attempt to match C comments by applying the pattern
-</P>
-<P>
-<pre>
- /\*.*\*/
-</PRE>
-</P>
-<P>
-to the string
-</P>
-<P>
-<pre>
- /* first command */ not comment /* second comment */
-</PRE>
-</P>
-<P>
-fails, because it matches the entire string owing to the greediness of the .*
-item.
-</P>
-<P>
-However, if a quantifier is followed by a question mark, it ceases to be
-greedy, and instead matches the minimum number of times possible, so the
-pattern
-</P>
-<P>
-<pre>
- /\*.*?\*/
-</PRE>
-</P>
-<P>
-does the right thing with the C comments. The meaning of the various
-quantifiers is not otherwise changed, just the preferred number of matches.
-Do not confuse this use of question mark with its use as a quantifier in its
-own right. Because it has two uses, it can sometimes appear doubled, as in
-</P>
-<P>
-<pre>
- \d??\d
-</PRE>
-</P>
-<P>
-which matches one digit by preference, but can match two if that is the only
-way the rest of the pattern matches.
-</P>
-<P>
-If the PCRE_UNGREEDY option is set (an option which is not available in Perl),
-the quantifiers are not greedy by default, but individual ones can be made
-greedy by following them with a question mark. In other words, it inverts the
-default behaviour.
-</P>
-<P>
-When a parenthesized subpattern is quantified with a minimum repeat count that
-is greater than 1 or with a limited maximum, more store is required for the
-compiled pattern, in proportion to the size of the minimum or maximum.
-</P>
-<P>
-If a pattern starts with .* or .{0,} and the PCRE_DOTALL option (equivalent
-to Perl's /s) is set, thus allowing the . to match newlines, the pattern is
-implicitly anchored, because whatever follows will be tried against every
-character position in the subject string, so there is no point in retrying the
-overall match at any position after the first. PCRE normally treats such a
-pattern as though it were preceded by \A.
-</P>
-<P>
-In cases where it is known that the subject string contains no newlines, it is
-worth setting PCRE_DOTALL in order to obtain this optimization, or
-alternatively using ^ to indicate anchoring explicitly.
-</P>
-<P>
-However, there is one situation where the optimization cannot be used. When .*
-is inside capturing parentheses that are the subject of a backreference
-elsewhere in the pattern, a match at the start may fail, and a later one
-succeed. Consider, for example:
-</P>
-<P>
-<pre>
- (.*)abc\1
-</PRE>
-</P>
-<P>
-If the subject is "xyz123abc123" the match point is the fourth character. For
-this reason, such a pattern is not implicitly anchored.
-</P>
-<P>
-When a capturing subpattern is repeated, the value captured is the substring
-that matched the final iteration. For example, after
-</P>
-<P>
-<pre>
- (tweedle[dume]{3}\s*)+
-</PRE>
-</P>
-<P>
-has matched "tweedledum tweedledee" the value of the captured substring is
-"tweedledee". However, if there are nested capturing subpatterns, the
-corresponding captured values may have been set in previous iterations. For
-example, after
-</P>
-<P>
-<pre>
- /(a|(b))+/
-</PRE>
-</P>
-<P>
-matches "aba" the value of the second captured substring is "b".
-</P>
-<br><a name="SEC13" href="#TOC1">ATOMIC GROUPING AND POSSESSIVE QUANTIFIERS</a><br>
-<P>
-With both maximizing and minimizing repetition, failure of what follows
-normally causes the repeated item to be re-evaluated to see if a different
-number of repeats allows the rest of the pattern to match. Sometimes it is
-useful to prevent this, either to change the nature of the match, or to cause
-it fail earlier than it otherwise might, when the author of the pattern knows
-there is no point in carrying on.
-</P>
-<P>
-Consider, for example, the pattern \d+foo when applied to the subject line
-</P>
-<P>
-<pre>
- 123456bar
-</PRE>
-</P>
-<P>
-After matching all 6 digits and then failing to match "foo", the normal
-action of the matcher is to try again with only 5 digits matching the \d+
-item, and then with 4, and so on, before ultimately failing. "Atomic grouping"
-(a term taken from Jeffrey Friedl's book) provides the means for specifying
-that once a subpattern has matched, it is not to be re-evaluated in this way.
-</P>
-<P>
-If we use atomic grouping for the previous example, the matcher would give up
-immediately on failing to match "foo" the first time. The notation is a kind of
-special parenthesis, starting with (?> as in this example:
-</P>
-<P>
-<pre>
- (?>\d+)foo
-</PRE>
-</P>
-<P>
-This kind of parenthesis "locks up" the part of the pattern it contains once
-it has matched, and a failure further into the pattern is prevented from
-backtracking into it. Backtracking past it to previous items, however, works as
-normal.
-</P>
-<P>
-An alternative description is that a subpattern of this type matches the string
-of characters that an identical standalone pattern would match, if anchored at
-the current point in the subject string.
-</P>
-<P>
-Atomic grouping subpatterns are not capturing subpatterns. Simple cases such as
-the above example can be thought of as a maximizing repeat that must swallow
-everything it can. So, while both \d+ and \d+? are prepared to adjust the
-number of digits they match in order to make the rest of the pattern match,
-(?>\d+) can only match an entire sequence of digits.
-</P>
-<P>
-Atomic groups in general can of course contain arbitrarily complicated
-subpatterns, and can be nested. However, when the subpattern for an atomic
-group is just a single repeated item, as in the example above, a simpler
-notation, called a "possessive quantifier" can be used. This consists of an
-additional + character following a quantifier. Using this notation, the
-previous example can be rewritten as
-</P>
-<P>
-<pre>
- \d++bar
-</PRE>
-</P>
-<P>
-Possessive quantifiers are always greedy; the setting of the PCRE_UNGREEDY
-option is ignored. They are a convenient notation for the simpler forms of
-atomic group. However, there is no difference in the meaning or processing of a
-possessive quantifier and the equivalent atomic group.
-</P>
-<P>
-The possessive quantifier syntax is an extension to the Perl syntax. It
-originates in Sun's Java package.
-</P>
-<P>
-When a pattern contains an unlimited repeat inside a subpattern that can itself
-be repeated an unlimited number of times, the use of an atomic group is the
-only way to avoid some failing matches taking a very long time indeed. The
-pattern
-</P>
-<P>
-<pre>
- (\D+|<\d+>)*[!?]
-</PRE>
-</P>
-<P>
-matches an unlimited number of substrings that either consist of non-digits, or
-digits enclosed in <>, followed by either ! or ?. When it matches, it runs
-quickly. However, if it is applied to
-</P>
-<P>
-<pre>
- aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
-</PRE>
-</P>
-<P>
-it takes a long time before reporting failure. This is because the string can
-be divided between the two repeats in a large number of ways, and all have to
-be tried. (The example used [!?] rather than a single character at the end,
-because both PCRE and Perl have an optimization that allows for fast failure
-when a single character is used. They remember the last single character that
-is required for a match, and fail early if it is not present in the string.)
-If the pattern is changed to
-</P>
-<P>
-<pre>
- ((?>\D+)|<\d+>)*[!?]
-</PRE>
-</P>
-<P>
-sequences of non-digits cannot be broken, and failure happens quickly.
-</P>
-<br><a name="SEC14" href="#TOC1">BACK REFERENCES</a><br>
-<P>
-Outside a character class, a backslash followed by a digit greater than 0 (and
-possibly further digits) is a back reference to a capturing subpattern earlier
-(that is, to its left) in the pattern, provided there have been that many
-previous capturing left parentheses.
-</P>
-<P>
-However, if the decimal number following the backslash is less than 10, it is
-always taken as a back reference, and causes an error only if there are not
-that many capturing left parentheses in the entire pattern. In other words, the
-parentheses that are referenced need not be to the left of the reference for
-numbers less than 10. See the section entitled "Backslash" above for further
-details of the handling of digits following a backslash.
-</P>
-<P>
-A back reference matches whatever actually matched the capturing subpattern in
-the current subject string, rather than anything matching the subpattern
-itself (see
-<a href="#subpatternsassubroutines">"Subpatterns as subroutines"</a>
-below for a way of doing that). So the pattern
-</P>
-<P>
-<pre>
- (sens|respons)e and \1ibility
-</PRE>
-</P>
-<P>
-matches "sense and sensibility" and "response and responsibility", but not
-"sense and responsibility". If caseful matching is in force at the time of the
-back reference, the case of letters is relevant. For example,
-</P>
-<P>
-<pre>
- ((?i)rah)\s+\1
-</PRE>
-</P>
-<P>
-matches "rah rah" and "RAH RAH", but not "RAH rah", even though the original
-capturing subpattern is matched caselessly.
-</P>
-<P>
-Back references to named subpatterns use the Python syntax (?P=name). We could
-rewrite the above example as follows:
-</P>
-<P>
-<pre>
- (?<p1>(?i)rah)\s+(?P=p1)
-</PRE>
-</P>
-<P>
-There may be more than one back reference to the same subpattern. If a
-subpattern has not actually been used in a particular match, any back
-references to it always fail. For example, the pattern
-</P>
-<P>
-<pre>
- (a|(bc))\2
-</PRE>
-</P>
-<P>
-always fails if it starts to match "a" rather than "bc". Because there may be
-many capturing parentheses in a pattern, all digits following the backslash are
-taken as part of a potential back reference number. If the pattern continues
-with a digit character, some delimiter must be used to terminate the back
-reference. If the PCRE_EXTENDED option is set, this can be whitespace.
-Otherwise an empty comment can be used.
-</P>
-<P>
-A back reference that occurs inside the parentheses to which it refers fails
-when the subpattern is first used, so, for example, (a\1) never matches.
-However, such references can be useful inside repeated subpatterns. For
-example, the pattern
-</P>
-<P>
-<pre>
- (a|b\1)+
-</PRE>
-</P>
-<P>
-matches any number of "a"s and also "aba", "ababbaa" etc. At each iteration of
-the subpattern, the back reference matches the character string corresponding
-to the previous iteration. In order for this to work, the pattern must be such
-that the first iteration does not need to match the back reference. This can be
-done using alternation, as in the example above, or by a quantifier with a
-minimum of zero.
-</P>
-<br><a name="SEC15" href="#TOC1">ASSERTIONS</a><br>
-<P>
-An assertion is a test on the characters following or preceding the current
-matching point that does not actually consume any characters. The simple
-assertions coded as \b, \B, \A, \G, \Z, \z, ^ and $ are described above.
-More complicated assertions are coded as subpatterns. There are two kinds:
-those that look ahead of the current position in the subject string, and those
-that look behind it.
-</P>
-<P>
-An assertion subpattern is matched in the normal way, except that it does not
-cause the current matching position to be changed. Lookahead assertions start
-with (?= for positive assertions and (?! for negative assertions. For example,
-</P>
-<P>
-<pre>
- \w+(?=;)
-</PRE>
-</P>
-<P>
-matches a word followed by a semicolon, but does not include the semicolon in
-the match, and
-</P>
-<P>
-<pre>
- foo(?!bar)
-</PRE>
-</P>
-<P>
-matches any occurrence of "foo" that is not followed by "bar". Note that the
-apparently similar pattern
-</P>
-<P>
-<pre>
- (?!foo)bar
-</PRE>
-</P>
-<P>
-does not find an occurrence of "bar" that is preceded by something other than
-"foo"; it finds any occurrence of "bar" whatsoever, because the assertion
-(?!foo) is always true when the next three characters are "bar". A
-lookbehind assertion is needed to achieve this effect.
-</P>
-<P>
-If you want to force a matching failure at some point in a pattern, the most
-convenient way to do it is with (?!) because an empty string always matches, so
-an assertion that requires there not to be an empty string must always fail.
-</P>
-<P>
-Lookbehind assertions start with (?<= for positive assertions and (?<! for
-negative assertions. For example,
-</P>
-<P>
-<pre>
- (?<!foo)bar
-</PRE>
-</P>
-<P>
-does find an occurrence of "bar" that is not preceded by "foo". The contents of
-a lookbehind assertion are restricted such that all the strings it matches must
-have a fixed length. However, if there are several alternatives, they do not
-all have to have the same fixed length. Thus
-</P>
-<P>
-<pre>
- (?<=bullock|donkey)
-</PRE>
-</P>
-<P>
-is permitted, but
-</P>
-<P>
-<pre>
- (?<!dogs?|cats?)
-</PRE>
-</P>
-<P>
-causes an error at compile time. Branches that match different length strings
-are permitted only at the top level of a lookbehind assertion. This is an
-extension compared with Perl (at least for 5.8), which requires all branches to
-match the same length of string. An assertion such as
-</P>
-<P>
-<pre>
- (?<=ab(c|de))
-</PRE>
-</P>
-<P>
-is not permitted, because its single top-level branch can match two different
-lengths, but it is acceptable if rewritten to use two top-level branches:
-</P>
-<P>
-<pre>
- (?<=abc|abde)
-</PRE>
-</P>
-<P>
-The implementation of lookbehind assertions is, for each alternative, to
-temporarily move the current position back by the fixed width and then try to
-match. If there are insufficient characters before the current position, the
-match is deemed to fail.
-</P>
-<P>
-PCRE does not allow the \C escape (which matches a single byte in UTF-8 mode)
-to appear in lookbehind assertions, because it makes it impossible to calculate
-the length of the lookbehind.
-</P>
-<P>
-Atomic groups can be used in conjunction with lookbehind assertions to specify
-efficient matching at the end of the subject string. Consider a simple pattern
-such as
-</P>
-<P>
-<pre>
- abcd$
-</PRE>
-</P>
-<P>
-when applied to a long string that does not match. Because matching proceeds
-from left to right, PCRE will look for each "a" in the subject and then see if
-what follows matches the rest of the pattern. If the pattern is specified as
-</P>
-<P>
-<pre>
- ^.*abcd$
-</PRE>
-</P>
-<P>
-the initial .* matches the entire string at first, but when this fails (because
-there is no following "a"), it backtracks to match all but the last character,
-then all but the last two characters, and so on. Once again the search for "a"
-covers the entire string, from right to left, so we are no better off. However,
-if the pattern is written as
-</P>
-<P>
-<pre>
- ^(?>.*)(?<=abcd)
-</PRE>
-</P>
-<P>
-or, equivalently,
-</P>
-<P>
-<pre>
- ^.*+(?<=abcd)
-</PRE>
-</P>
-<P>
-there can be no backtracking for the .* item; it can match only the entire
-string. The subsequent lookbehind assertion does a single test on the last four
-characters. If it fails, the match fails immediately. For long strings, this
-approach makes a significant difference to the processing time.
-</P>
-<P>
-Several assertions (of any sort) may occur in succession. For example,
-</P>
-<P>
-<pre>
- (?<=\d{3})(?<!999)foo
-</PRE>
-</P>
-<P>
-matches "foo" preceded by three digits that are not "999". Notice that each of
-the assertions is applied independently at the same point in the subject
-string. First there is a check that the previous three characters are all
-digits, and then there is a check that the same three characters are not "999".
-This pattern does <i>not</i> match "foo" preceded by six characters, the first
-of which are digits and the last three of which are not "999". For example, it
-doesn't match "123abcfoo". A pattern to do that is
-</P>
-<P>
-<pre>
- (?<=\d{3}...)(?<!999)foo
-</PRE>
-</P>
-<P>
-This time the first assertion looks at the preceding six characters, checking
-that the first three are digits, and then the second assertion checks that the
-preceding three characters are not "999".
-</P>
-<P>
-Assertions can be nested in any combination. For example,
-</P>
-<P>
-<pre>
- (?<=(?<!foo)bar)baz
-</PRE>
-</P>
-<P>
-matches an occurrence of "baz" that is preceded by "bar" which in turn is not
-preceded by "foo", while
-</P>
-<P>
-<pre>
- (?<=\d{3}(?!999)...)foo
-</PRE>
-</P>
-<P>
-is another pattern which matches "foo" preceded by three digits and any three
-characters that are not "999".
-</P>
-<P>
-Assertion subpatterns are not capturing subpatterns, and may not be repeated,
-because it makes no sense to assert the same thing several times. If any kind
-of assertion contains capturing subpatterns within it, these are counted for
-the purposes of numbering the capturing subpatterns in the whole pattern.
-However, substring capturing is carried out only for positive assertions,
-because it does not make sense for negative assertions.
-</P>
-<br><a name="SEC16" href="#TOC1">CONDITIONAL SUBPATTERNS</a><br>
-<P>
-It is possible to cause the matching process to obey a subpattern
-conditionally or to choose between two alternative subpatterns, depending on
-the result of an assertion, or whether a previous capturing subpattern matched
-or not. The two possible forms of conditional subpattern are
-</P>
-<P>
-<pre>
- (?(condition)yes-pattern)
- (?(condition)yes-pattern|no-pattern)
-</PRE>
-</P>
-<P>
-If the condition is satisfied, the yes-pattern is used; otherwise the
-no-pattern (if present) is used. If there are more than two alternatives in the
-subpattern, a compile-time error occurs.
-</P>
-<P>
-There are three kinds of condition. If the text between the parentheses
-consists of a sequence of digits, the condition is satisfied if the capturing
-subpattern of that number has previously matched. The number must be greater
-than zero. Consider the following pattern, which contains non-significant white
-space to make it more readable (assume the PCRE_EXTENDED option) and to divide
-it into three parts for ease of discussion:
-</P>
-<P>
-<pre>
- ( \( )? [^()]+ (?(1) \) )
-</PRE>
-</P>
-<P>
-The first part matches an optional opening parenthesis, and if that
-character is present, sets it as the first captured substring. The second part
-matches one or more characters that are not parentheses. The third part is a
-conditional subpattern that tests whether the first set of parentheses matched
-or not. If they did, that is, if subject started with an opening parenthesis,
-the condition is true, and so the yes-pattern is executed and a closing
-parenthesis is required. Otherwise, since no-pattern is not present, the
-subpattern matches nothing. In other words, this pattern matches a sequence of
-non-parentheses, optionally enclosed in parentheses.
-</P>
-<P>
-If the condition is the string (R), it is satisfied if a recursive call to the
-pattern or subpattern has been made. At "top level", the condition is false.
-This is a PCRE extension. Recursive patterns are described in the next section.
-</P>
-<P>
-If the condition is not a sequence of digits or (R), it must be an assertion.
-This may be a positive or negative lookahead or lookbehind assertion. Consider
-this pattern, again containing non-significant white space, and with the two
-alternatives on the second line:
-</P>
-<P>
-<pre>
- (?(?=[^a-z]*[a-z])
- \d{2}-[a-z]{3}-\d{2} | \d{2}-\d{2}-\d{2} )
-</PRE>
-</P>
-<P>
-The condition is a positive lookahead assertion that matches an optional
-sequence of non-letters followed by a letter. In other words, it tests for the
-presence of at least one letter in the subject. If a letter is found, the
-subject is matched against the first alternative; otherwise it is matched
-against the second. This pattern matches strings in one of the two forms
-dd-aaa-dd or dd-dd-dd, where aaa are letters and dd are digits.
-</P>
-<br><a name="SEC17" href="#TOC1">COMMENTS</a><br>
-<P>
-The sequence (?# marks the start of a comment which continues up to the next
-closing parenthesis. Nested parentheses are not permitted. The characters
-that make up a comment play no part in the pattern matching at all.
-</P>
-<P>
-If the PCRE_EXTENDED option is set, an unescaped # character outside a
-character class introduces a comment that continues up to the next newline
-character in the pattern.
-</P>
-<br><a name="SEC18" href="#TOC1">RECURSIVE PATTERNS</a><br>
-<P>
-Consider the problem of matching a string in parentheses, allowing for
-unlimited nested parentheses. Without the use of recursion, the best that can
-be done is to use a pattern that matches up to some fixed depth of nesting. It
-is not possible to handle an arbitrary nesting depth. Perl has provided an
-experimental facility that allows regular expressions to recurse (amongst other
-things). It does this by interpolating Perl code in the expression at run time,
-and the code can refer to the expression itself. A Perl pattern to solve the
-parentheses problem can be created like this:
-</P>
-<P>
-<pre>
- $re = qr{\( (?: (?>[^()]+) | (?p{$re}) )* \)}x;
-</PRE>
-</P>
-<P>
-The (?p{...}) item interpolates Perl code at run time, and in this case refers
-recursively to the pattern in which it appears. Obviously, PCRE cannot support
-the interpolation of Perl code. Instead, it supports some special syntax for
-recursion of the entire pattern, and also for individual subpattern recursion.
-</P>
-<P>
-The special item that consists of (? followed by a number greater than zero and
-a closing parenthesis is a recursive call of the subpattern of the given
-number, provided that it occurs inside that subpattern. (If not, it is a
-"subroutine" call, which is described in the next section.) The special item
-(?R) is a recursive call of the entire regular expression.
-</P>
-<P>
-For example, this PCRE pattern solves the nested parentheses problem (assume
-the PCRE_EXTENDED option is set so that white space is ignored):
-</P>
-<P>
-<pre>
- \( ( (?>[^()]+) | (?R) )* \)
-</PRE>
-</P>
-<P>
-First it matches an opening parenthesis. Then it matches any number of
-substrings which can either be a sequence of non-parentheses, or a recursive
-match of the pattern itself (that is a correctly parenthesized substring).
-Finally there is a closing parenthesis.
-</P>
-<P>
-If this were part of a larger pattern, you would not want to recurse the entire
-pattern, so instead you could use this:
-</P>
-<P>
-<pre>
- ( \( ( (?>[^()]+) | (?1) )* \) )
-</PRE>
-</P>
-<P>
-We have put the pattern into parentheses, and caused the recursion to refer to
-them instead of the whole pattern. In a larger pattern, keeping track of
-parenthesis numbers can be tricky. It may be more convenient to use named
-parentheses instead. For this, PCRE uses (?P>name), which is an extension to
-the Python syntax that PCRE uses for named parentheses (Perl does not provide
-named parentheses). We could rewrite the above example as follows:
-</P>
-<P>
-<pre>
- (?P<pn> \( ( (?>[^()]+) | (?P>pn) )* \) )
-</PRE>
-</P>
-<P>
-This particular example pattern contains nested unlimited repeats, and so the
-use of atomic grouping for matching strings of non-parentheses is important
-when applying the pattern to strings that do not match. For example, when this
-pattern is applied to
-</P>
-<P>
-<pre>
- (aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa()
-</PRE>
-</P>
-<P>
-it yields "no match" quickly. However, if atomic grouping is not used,
-the match runs for a very long time indeed because there are so many different
-ways the + and * repeats can carve up the subject, and all have to be tested
-before failure can be reported.
-</P>
-<P>
-At the end of a match, the values set for any capturing subpatterns are those
-from the outermost level of the recursion at which the subpattern value is set.
-If you want to obtain intermediate values, a callout function can be used (see
-below and the
-<a href="pcrecallout.html"><b>pcrecallout</b></a>
-documentation). If the pattern above is matched against
-</P>
-<P>
-<pre>
- (ab(cd)ef)
-</PRE>
-</P>
-<P>
-the value for the capturing parentheses is "ef", which is the last value taken
-on at the top level. If additional parentheses are added, giving
-</P>
-<P>
-<pre>
- \( ( ( (?>[^()]+) | (?R) )* ) \)
- ^ ^
- ^ ^
-</PRE>
-</P>
-<P>
-the string they capture is "ab(cd)ef", the contents of the top level
-parentheses. If there are more than 15 capturing parentheses in a pattern, PCRE
-has to obtain extra memory to store data during a recursion, which it does by
-using <b>pcre_malloc</b>, freeing it via <b>pcre_free</b> afterwards. If no
-memory can be obtained, the match fails with the PCRE_ERROR_NOMEMORY error.
-</P>
-<P>
-Do not confuse the (?R) item with the condition (R), which tests for recursion.
-Consider this pattern, which matches text in angle brackets, allowing for
-arbitrary nesting. Only digits are allowed in nested brackets (that is, when
-recursing), whereas any characters are permitted at the outer level.
-</P>
-<P>
-<pre>
- < (?: (?(R) \d++ | [^<>]*+) | (?R)) * >
-</PRE>
-</P>
-<P>
-In this pattern, (?(R) is the start of a conditional subpattern, with two
-different alternatives for the recursive and non-recursive cases. The (?R) item
-is the actual recursive call.
-</P>
-<a name="subpatternsassubroutines"></a><br><a name="SEC19" href="#TOC1">SUBPATTERNS AS SUBROUTINES</a><br>
-<P>
-If the syntax for a recursive subpattern reference (either by number or by
-name) is used outside the parentheses to which it refers, it operates like a
-subroutine in a programming language. An earlier example pointed out that the
-pattern
-</P>
-<P>
-<pre>
- (sens|respons)e and \1ibility
-</PRE>
-</P>
-<P>
-matches "sense and sensibility" and "response and responsibility", but not
-"sense and responsibility". If instead the pattern
-</P>
-<P>
-<pre>
- (sens|respons)e and (?1)ibility
-</PRE>
-</P>
-<P>
-is used, it does match "sense and responsibility" as well as the other two
-strings. Such references must, however, follow the subpattern to which they
-refer.
-</P>
-<br><a name="SEC20" href="#TOC1">CALLOUTS</a><br>
-<P>
-Perl has a feature whereby using the sequence (?{...}) causes arbitrary Perl
-code to be obeyed in the middle of matching a regular expression. This makes it
-possible, amongst other things, to extract different substrings that match the
-same pair of parentheses when there is a repetition.
-</P>
-<P>
-PCRE provides a similar feature, but of course it cannot obey arbitrary Perl
-code. The feature is called "callout". The caller of PCRE provides an external
-function by putting its entry point in the global variable <i>pcre_callout</i>.
-By default, this variable contains NULL, which disables all calling out.
-</P>
-<P>
-Within a regular expression, (?C) indicates the points at which the external
-function is to be called. If you want to identify different callout points, you
-can put a number less than 256 after the letter C. The default value is zero.
-For example, this pattern has two callout points:
-</P>
-<P>
-<pre>
- (?C1)\dabc(?C2)def
-</PRE>
-</P>
-<P>
-During matching, when PCRE reaches a callout point (and <i>pcre_callout</i> is
-set), the external function is called. It is provided with the number of the
-callout, and, optionally, one item of data originally supplied by the caller of
-<b>pcre_exec()</b>. The callout function may cause matching to backtrack, or to
-fail altogether. A complete description of the interface to the callout
-function is given in the
-<a href="pcrecallout.html"><b>pcrecallout</b></a>
-documentation.

-# The allow_split_ops token causes the server to always give chanop status

-# Port [REQUIRED]
-# The Port blocks define where the server will accept connections. At
-# least one Port block is required to start.
-#
-# Old conf format equivalents:
-# M::bind::port
-# P:ipmask:bind::port
-
-port {

- bind 127.0.0.1; # IP address to listen on
- ipmask 127.0.*.*; # Mask to accept connections from
- flags S; # Allow SSL connections on this port
-};
-
-# If a bind address is not specified, the server listens on all available
-# interfaces.
-#
-# The ipmask token is used to limit the port to connections from the
-# specified IP mask. Only a simple mask is supported, consisting of a *
-# where one component of the address is (e.g. "192.168.*.*").
-#
-# There may be multiple Port blocks.

-# Class [RECOMMENDED]
-# The Class blocks define the connection classes used by the Allow, Oper,
-# and Connect blocks. While the server will start without a Class block,
-# it will not be usable.
-#
-# Old conf format equivalents:
-# Y:name:pingfreq::maxusers:maxsendq (for clients)
-# Y:name:pingfreq:connfreq:maxlinks:maxsendq (for servers)
-
-class {
- // required tokens
- name users; # Name of the class
- pingfreq 90; # PING idle connection every N seconds
- maxsendq 100000; # Send buffer limit
-
- // optional, for Allow classes only:
- maxusers 100; # Maximum number of clients
- maxclones 2:20; # Maximum IP:site clones
- maxrecvq 2560; # client excess flood threshold
-
- // optional, for Connect classes only:
- connfreq 300; # Try autoconnect every N seconds
- maxlinks 1; # Autoconnect if less than N links in class
-};
-
-# Idle connections are polled with the PING command every pingfreq seconds.
-#
-# The maxsendq token controls the size of the internal send buffer, used
-# when a connection cannot accept large amounts of data at once. Certain
-# server commands emit such large amounts of data. As an example metric,
-# a 100KB user send queue can support a WHO <channel> query for a channel
-# with approximately 700 users. Large amounts of data are also generated
-# when two servers link and synchronize network state. If the send queue
-# limit is exceeded, the connection is terminated.
-#
-# For classes used in the Allow blocks, the maxusers token limits the
-# number of clients that may exist in this class. This is the most common
-# general user limit for the server. If this limit is reached, additional
-# clients will be rejected with a "server busy" message. This token must
-# not be specified for classes used in the Connect blocks.
-#
-# For classes used in the Allow blocks, the maxclones token limits the
-# number of clients that may connect from the same place in this class.
-# The first number refers to connections from the same IP (10.0.0.5); it
-# may be optionally followed by a colon ':' and a second number, which
-# refers to connections from the same site (10.0.0.*). If this limit is
-# reached, clients will be rejected with a "too many connections from your
-# host/site" message. Limits defined here override the defaults as
-# configured in the Options block. If a site limit is not supplied here,
-# clients in this class will effectively have no site limit; the default
-# limit will not be used. This token must not be specified for classes
-# used in the Connect blocks.
-#
-# For classes used in the Connect blocks, the connfreq token specifies the
-# frequency at which autoconnections are tried. This token works together
-# with maxlinks, which specifies the maximum number of servers in this
-# class to autoconnect to. For an autoconnection to take place, the
-# Connect block must have a valid port token, and there must be less than
-# maxlinks connected servers in this class. The connfreq and maxlinks
-# tokens must not be specified for classes used in the Allow or Oper
-# blocks.
-#
-# A "default" class is created internally using definitions in config.h.
-# This class is used when no other class is specified, but its settings are
-# not useful for most situations. Custom classes are strongly suggested.
-#
-# There may be multiple Class blocks; at least one is recommended.

-# Allow [RECOMMENDED]
-# The Allow blocks define the hosts connections are allowed from, and
-# places them into classes. While the server will start without an Allow
-# block, it will not be usable.
-#
-# Old conf format equivalents:
-# I:ipmask:passwd:host:port:class
-
-allow {
- // required tokens
- host *; # Resolved host mask (optional if using ipmask)
- ipmask *; # Unresolved IP mask (optional if using host)
-
- // optional tokens
- port 6667; # Apply block to this port only
- passwd secret; # Require password for connection
- flags mCFT; # Special flags for this connection
- class users; # Place connections in this class
-};
-
-# The server uses a default-deny policy for incoming connections; at least
-# one Allow block must be supplied if you wish to use your server.
-#
-# The host and ipmask tokens specify which connections this block matches.
-# The server always performs DNS and ident lookups for connections. If DNS
-# cannot find a hostname, the IP is used instead. If ident cannot get a
-# valid response, "unknown" is used during this stage. The client's
-# resolved hostname, IP address, ident reply, and username (from the USER
-# line) are used according to the results of the matches described below.
-#
-# The host token attempts to match first against the resolved hostname if
-# available, then against the IP address. To include the connection's
-# ident response in the match, use a mask in the form "ident@host". If a
-# client matches this token, it appears on IRC using its resolved hostname.
-#
-# The ipmask token attempts to match against the IP address only. To
-# include the connection's ident response in the match, use a mask in the
-# form "ident@host". If a client matches this token, it appears on IRC
-# using its IP address, even if its hostname was resolved.
-#
-# If the matching mask used ident ("ident@host" instead of "host"), and no
-# ident response was received from the client, it appears on IRC with its
-# username prefixed with '~'. If the matching mask used only the "host"
-# form, the client's username is not prefixed. If a valid ident response
-# was received, it is always used (without prefix), regardless of the mask
-# form.
-#
-# Only one of the host and ipmask tokens is needed; if both are used, host
-# is matched first. For typical configurations, using only the host token
-# with a "*@host" or "ident@host" mask is recommended.
-#
-# Examples:
-# // client with username "user", ident "ident", hostname "name"
-# host ident@*; # appears as ident@name
-# ipmask *; # appears as ident@10.0.0.1
-#
-# // same client without ident response
-# host *; # appears as user@name
-# host *@*; # appears as ~user@name
-# ipmask unknown@*; # appears as ~user@10.0.0.1
-#
-# The port token limits this block to match connections to the specified
-# port only.
-#
-# The passwd token requires that matching connections supply a password to
-# use the server. Clients can send a password string in multiple forms,
-# depending on which passwords need to be used. The basic format is:
-#
-# [passwd][:][opername:operpass][:][nickpass]
-#
-# If the Allow block requires a password, it must be supplied at the front
-# of the string. If operator hostmasking is enabled (via the flags token
-# described below), the client can mask itself by supplying a "name:passwd"
-# string as defined in an Oper block. When masked, a client appears on IRC
-# using the Oper block name for its ident, and the Options block
-# staff_address for its hostname. Any remaining passwords are sent to
-# NickServ in an SIDENTIFY command. All password components must be
-# separated from each other by a ':' colon.
-#
-# Using the examples in this file, a client could connect with the password
-# string "secret:johndoe:secret" and be masked as johndoe@staff.net.
-#
-# The flags token allows special behavior to be assigned to this
-# connection, using a set of single-letter options. The available flags
-# are:
-#
-# m Enable operator hostmasking
-# C Bypass clone limiting
-# F Force umode +F to bypass message flood checks
-# T Disable rapid (re)connection throttling
-#
-# When operator hostmasking is enabled, a matching client can connect using
-# a special password to be masked, as described for the passwd token above.
-#
-# Normally all clients are subjected to a clone limit check when they
-# connect, as configured in the Options and Class blocks. The C flag skips
-# this check for matching clients, allowing them to have an unrestricted
-# number of connections.
-#
-# The F flag forces matching clients to always have usermode +F, to avoid
-# various message flood checks. This flag is intended for special bots and
-# should not be used for server operators; opers can make use of the F
-# access flag as described in the Oper block documentation.
-#
-# By default, the server throttles rapid (re)connections from a single IP
-# address, to help reduce abuse and load. The T flag disables this
-# mechanism for matching clients. To qualify, a client must send valid
-# NICK and USER messages to register the connection, and stay connected
-# long enough to complete the ident and DNS lookups. However, a correct
-# password is not required.
-#
-# The class token specifies the connection Class to place matching
-# connections in. If not specified, the default class is used; see the
-# Class block description for details.
-#
-# There may be multiple Allow blocks; they are matched in the order they
-# appear.

- * This file defines five types of data structures: singly-linked lists,
- * singly-linked tail queues, lists, tail queues, and circular queues.
- *
- * A singly-linked list is headed by a single forward pointer. The elements
- * are singly linked for minimum space and pointer manipulation overhead at
- * the expense of O(n) removal for arbitrary elements. New elements can be
- * added to the list after an existing element or at the head of the list.
- * Elements being removed from the head of the list should use the explicit
- * macro for this purpose for optimum efficiency. A singly-linked list may
- * only be traversed in the forward direction. Singly-linked lists are ideal
- * for applications with large datasets and few or no removals or for
- * implementing a LIFO queue.
- *
- * A singly-linked tail queue is headed by a pair of pointers, one to the
- * head of the list and the other to the tail of the list. The elements are
- * singly linked for minimum space and pointer manipulation overhead at the
- * expense of O(n) removal for arbitrary elements. New elements can be added
- * to the list after an existing element, at the head of the list, or at the
- * end of the list. Elements being removed from the head of the tail queue
- * should use the explicit macro for this purpose for optimum efficiency.
- * A singly-linked tail queue may only be traversed in the forward direction.
- * Singly-linked tail queues are ideal for applications with large datasets
- * and few or no removals or for implementing a FIFO queue.
- *
- * A list is headed by a single forward pointer (or an array of forward
- * pointers for a hash table header). The elements are doubly linked
- * so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before
- * or after an existing element or at the head of the list. A list
- * may only be traversed in the forward direction.
- *
- * A tail queue is headed by a pair of pointers, one to the head of the
- * list and the other to the tail of the list. The elements are doubly
- * linked so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before or
- * after an existing element, at the head of the list, or at the end of
- * the list. A tail queue may be traversed in either direction.
- *
- * A circle queue is headed by a pair of pointers, one to the head of the
- * list and the other to the tail of the list. The elements are doubly
- * linked so that an arbitrary element can be removed without a need to
- * traverse the list. New elements can be added to the list before or after
- * an existing element, at the head of the list, or at the end of the list.
- * A circle queue may be traversed in either direction, but has a more
- * complex end of list detection.
- *
- * For details on the use of these macros, see the queue(3) manual page.

-/* notes on confparse.c
- * While this initial revision requires a fair bit of trimming down,
- * my primary goal right now was to build an extendable system that will
- * allow for fairly easy changes to the config file.
- * Heres a few notes on how to go about that.
- *
- * The parser works on two primary depths - blocks and tokens:
- *
- * block {
- * token value;
- * token "string value";
- * token 123; # int value
- * token; # nonvar token
- * };
- *
- * It can also parse non-token blocks:
- *
- * block (
- * "string string string";
- * "string blah";
- * };
- *
- * Blocks are defined by tconftab (in confparse.h)
- * Tokens are defined by sconftab (^^^^^^^^^^^^^^)
- *
- * Each block must have a function that takes the values collected
- * and checks them against the requirements. These functions are also
- * handy for getting variables out of the array that they are stored in.
- *
- * The array variables are placed in (an array of cVar structs) contains
- * all values for the the block, and the corrisponding sconftab item.
- *
- * I feel the need to rewrite large sections of this still, but I'll just
- * be happy to have it working for now.

- RECURSION IN THE match() FUNCTION
-
-The match() function is highly recursive. Some regular expressions can cause
-it to recurse thousands of times. I was writing for Unix, so I just let it
-call itself recursively. This uses the stack for saving everything that has
-to be saved for a recursive call. On Unix, the stack can be large, and this
-works fine.
-
-It turns out that on non-Unix systems there are problems with programs that
-use a lot of stack. (This despite the fact that every last chip has oodles
-of memory these days, and techniques for extending the stack have been known
-for decades.) So....
-
-There is a fudge, triggered by defining NO_RECURSE, which avoids recursive
-calls by keeping local variables that need to be preserved in blocks of memory
-obtained from malloc instead instead of on the stack. Macros are used to
-achieve this so that the actual code doesn't look very different to what it
-always used to.
