+ SQUERY <target>[,<target>[,...]] <message>
+ .
+ Send a <message> to a given <target> IRC service, and report all
+ errors.
+ .
+ The "SQUERY" command exactly behaves like the "PRIVMSG" command, but
+ enforces that the <target> of the <message> is an IRC service.
+ Please see the help text of the "PRIVMSG" command for a detailed
+ description of the parameters!
+ .
+ If a user wants to interact with IRC services, he should use "SQUERY"
+ instead of "PRIVMSG" or "NOTICE": only "SQUERY makes sure that no
+ regular user, which uses the nickname of an IRC service, receives
+ the command in error, for example during a "net split"!
