-The source code of ngIRCd is maintained using the "Concurrent Versions
-System" (CVS). Thereby several developers can work with the source tree at
-the same time.
-
-
-I. Anonymous read-only Access
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-To access the source tree anonymously in read-only mode, follow these steps:
-
-Login to the CVS server:
-
- $ cvs -d:pserver:anonymous@ngircd.barton.de:/srv/cvs/ngircd login
-
-Use "anonymous" as user name and no password (just hit Return). Now you can
-check out the sources:
-
- $ cvs -d:pserver:anonymous@ngircd.barton.de:/srv/cvs/ngircd checkout ngircd
-
-Thereby a new folder "ngircd" will be created containing all the individual
-source files. (Substitute the last "ngircd" with "website" to check out all
-the files of the homepage of ngIRCd.)
-
-The newly created folder ("ngircd" or "website") is the "working folder", all
-CVS commands will be executed from within this folder in the future.
-
-Please note: When checking out a fresh copy of ngIRCd from CVS, the
-configure script doesn't exist; you have to run the autogen.sh shell script
-(which is included in the source tree) to generate it. This requires you to
-have GNU automake and GNU autoconf installed on your system.
-
-Updating the CVS tree:
-
- $ cvs update -d -P [<filename>]
-
-You can update a single file or the complete source tree.
-
-
-III. Write Access
-~~~~~~~~~~~~~~~~~
-If you want to contribute a couple of patches and write access to the CVS
-repository would be handy, please contact Alex Barton, <alex@barton.de>.

-Q: I am running Linux and ngircd dies on startup with the follwing errors:
-   IO subsystem: epoll (hint size 100, initial maxfd 100, masterfd -1).
-   Cannot initialize IO routines: Function not implemented
-   Server isn't listening on a single port!
-   ngircd exiting due to fatal errors!
-A: epoll is only supported on 2.6 Linux kernels. Either use a 2.6 kernel, or
-   re-run configure with the --without-epoll parameter. After configure
-   completed, you should see select() being listed as IO backend:

-II.2 Exchange channel-modes, topics, and persistent channels
+II.2 Enhanced Server Handshake
+
+The "enhanced server handshake" is used when both servers support this IRC+
+extension, which is indicated by the 'H' flag in the <serverflags> sent with
+the PASS command, see section II.1.
+
+It basically means, that after exchanging the PASS and SERVER commands the
+server is not registered in the network (as usual), but that IRC numerics
+are exchanged until the numeric 376 (ENDOFMOTD) is received. Afterwards the
+peer is registered in the network as with the regular IRC protocol.
+
+A server implementing the enhanced server handshake (and indicating this
+using 'H' in the <serverflags>) MUST ignore all unknown numerics to it
+silently.
+
+In addition, such a server should at least send the numeric 005 (ISUPPORT)
+to its peer, containing the following information. Syntax: <key>=<value>,
+one token per IRC parameter. If the server has to send more than 12 token
+it must send separate ISUPPORT numerics (this is a limitation of the IRC
+protocol which allows at max 15 arguments per command).
+
+ - NICKLEN: Maximum nickname length. Default: 9.
+ - CASEMAPPING: Case mapping used for nick- and channel name comparing.
+   Default: "ascii", the chars [a-z] are lowercase of [A-Z].
+ - PREFIX: List of channel modes a person can get and the respective prefix
+   a channel or nickname will get in case the person has it. The order of the
+   modes goes from most powerful to least powerful. Default: "(ov)@+"
+ - CHANTYPES: Supported channel prefixes. Default: "#".
+ - CHANMODES: List of channel modes for 4 types, separated by comma (","):
+   Mode that adds or removes a nick or address to a list, mode that changes
+   a setting (both have always has a parameter), mode that changes a setting
+   and only has a parameter when set, and mode that changes a setting and
+   never has a parameter. For example "bI,k,l,imnPst".
+ - CHANLIMIT: Maximum number of channels allowed to join by channel prefix,
+   for example "#:10".
+
+Please see <http://www.irc.org/tech_docs/005.html> for details.
+
+The information exchanged using ISUPPORT can be used to detect configuration
+incompatibilities (different maximum nick name length, for example) and
+therefore to disconnect the peer prior to registering it in the network.
