+ Tests the presence of a connection to a client or server.

+ If no <target> has been given, the local server is used. User clients
+ can only use other servers as <target>, no user clients.
+ .
+ A PING message results in a PONG reply containing the <token>, which
+ can be arbitrary text.
+
+ Please note:
+ The RFCs state that the <token> parameter is used to specify the
+ origin of the PING command when forwared in the network, but this
+ is not the case: the sender is specified using the prefix as usual,
+ and the parameter is used to identify the PONG reply in practice.

+ The <token> is the arbitrary text received in the "PING" command and

- This command is a reply to the PING command and works in much the

+ When received from a user, the server acknowledges this by sending

+ Register (and authenticate) a new user session with a short <username>
+ and a human-readable <realname>.
.
- This command is used at the beginning of a connection to specify the
- <user>name, hostname, <realname> and initial user <modes> of the
- connecting client.
+ The parameter <hostname> is only used when received by an other server
+ and ignored otherwise; and the parameter <unused> is always ignored.
+ But both parameters are required on each invocation by the protocol
+ and can be set to arbitrary characters/text when not used.
.
- <realname> may contain spaces, and thus must be prefixed with a colon.
+ If <username> contains an "@" character, the full <username> is used
+ for authentication, but only the first part up to this character is
+ set as "user name" for this session.

+ user name and host name of users instead of their own.
+ .
+ It must be the very first command sent to the server, even before
+ USER and NICK commands!
+ .
+ The <password> must be set in the server configuration file to prevent
+ unauthorized clients to fake their identity; it is an arbitrary string.

General Commands
See doc/Modes.txt for more information.
- NOTICE
- NOTICE <target> <notice>
+ NOTICE <target>[,<target>[,...]] <message>
.
- Send <notice> to <target> (nick or channel).
+ Send a <message> to a given <target>, which can be a user or a
+ channel, but DON'T report any error.
.
- This command works similarly to PRIVMSG, except automatic replies must
- never be sent in reply to NOTICE messages.
+ The "NOTICE" command exactly behaves like the "PRIVMSG" command, but
+ doesn't report any errors it encounters (like an unknown <target>).
+ Please see the help text of the "PRIVMSG" command for a detailed
+ description of the parameters!
+
+ References:
+ - RFC 2812, 2.3.1 "Message format in Augmented BNF"
+ - RFC 2812, 3.3 "Sending messages"
+ - RFC 2812, 3.3.2 "Notice"
- PRIVMSG
- PRIVMSG <target> <message>
+ PRIVMSG <target>[,<target>[,...]] <message>
.
- Send <message> to <target> (nick or channel).
+ Send a <message> to a given <target>, which can be a user or a
+ channel, and report all errors.
.
- Common IRC clients use MSG as PRIVMSG alias.
- (Some clients use "QUERY <nick> [<message>]" to open a private chat.)
+ The <target> must follow one of these syntax variants:
+ .
+ - <nickname>
+ - <channel>
+ - <user>[%<host>]@<server>
+ - <user>%<host>
+ - <nickname>!<user>@<host>
+ .
+ If the <target> is a user, a private message is sent directly to this
+ user; if it resolves to a channel name, a public message is sent
+ to all the members of that channel.
+ .
+ In addition, IRC Ops can use these two forms to specify the <target>:
+ .
+ - #<hostmask>
+ - #<servermask>
+ .
+ The <mask> can contain the wildcard characters "*" and "?", but must
+ contain at least one dot (".") and no wildcard after the last one.
+ Then, the <message> is sent to all users matching this <mask>.
+ .
+ All warnings and errors are reported back to the initiator using
+ numeric status codes, which is the only difference to the "NOTICE"
+ command, which doesn't report back any errors or warnings at all.
+ .
+ Please note that clients often use "MSG" as an alias to PRIVMSG, and
+ a command "QUERY <nick> [<message>]" to initiate private chats. Both
+ are command extensions of the client and never sent to the server.
