usage: chname <user>[@<host>] [<real name>]

    /chname changes your irc username to <user>.  It supports the hacked
    ident daemon as well.  If <host> is specified, your source host is
    changed to that via virtual hosting.  If <real name> is specified,
    that is changed to what is there as well.
