Synopsis:
   realname [<text>]

Description:
   REALNAME is used to set the client's IRCNAME (hence the alias, below).
   The IRCNAME is an arbitrary text string that is displayed in WHOIS and
   WHO output.  Typically it contains the user's real name, but it may
   contain anything the user desires.  Use of this command will override
   any previous setting to REALNAME, as well as the $IRCNAME environment
   variable (if set).

Aliases:
   IRCNAME is functionally equivalent to REALNAME.

See Also:
   Environment(7); reconnect(1); set(4) realname

Restrictions:
   This command does not change the IRCNAME on the fly.  The client must
   disconnect and reconnect to a server before it will take effect.
