1.34 [KK 2007-04-03] Added SVN revision number to the overall version
     ID, so that tracking historical versions becomes easier. Added
     flag -t which causes tabular display in 'crossroads status'
     (useful for automated parsing, e.g. for heartbeat scripts).
     [KK 2007-04-06] Increased max # of back ends per service to
     20. (In the future this should be a dynamic value - but it'll
     take code changes; so for now, I'm taking 20.)
