[Orgmode] Weekday repeaters, and filtering scheduled tasks.

[Avdi Grimm]

I couldn't find a list of repeaters.  Is there by any chance a weekday
repeater that will skip Sat-Sun?

Also, how would I set up an agenda view to show:

 - All UNSCHEDULED tasks with the NEXT keyword.
 - All scheduled tasks with the NEXT keyword which are DUE or OVERDUE
 - NO tasks which are scheduled for future dates.

Thanks!
