Usage: BINV <nick [flag] | pattern1 pattern2 ... patterns> 
   Channel mode (+I) that makes possible for the specified nick
   to JOIN your current channel even if channel is invite-only.
Flags:
	a	invites the IP address, eg. *!*@207.240.167.*
	c	invites the country or inet organization, eg. *!*@*.net
	h	invites the nick's host, eg. *!*@ppp-80.mistik.net
	f	invites the nick's host with a pattern *!*@*mistik.net
	n	Simple *!*user@*host inv mask (default)
	u	invites only the username used by a nick, eg. *!*srfrog@*

Exception types: c=country e=eleet n=normal s=site f=freebie u=username

ie. /BINV SrfRoG			if SrfRoG is online. 
    /BINV cag@* srfrog@* lice@*		multiple on usernames.
    /BINV srfrog@*.mistik.net *@*.com	specific hosts
    /BINV SrfRoG!*@*.ed			SrfRoG's under *.edu.

Note: IP addresses and hacked usernames are appropiately masked and
      marked. Only one flag can be specified for a given nick. When
      pattern(s) are used, flags are ignored.

Our BINV procedure is smart enough to remove any conflicting invites before
doing the actual marking.
