+09Jun00=======================================================================
+1. change some print commands in DXMsg to dbg('err'...
+2. overloaded confess, croak et al into DXDebug and removed Carp from
+everywhere and checked that the necessary debugging really does go into
+the debug files now.
+3. changed print statements in cluster.pl to dbg('err',... so they go into
+the debug files as well.
+4. Altered the logic around duplicate spots, reduced the length of comment
+checked to 20 characters (this should solve some problems including those
+people sucking ar-cluster spots with prefixes in the extreme rh end).
