[editor's note: this commit combines approximate 4 months of furious releases of Andy Dougherty and Larry Wall - see pod/perlhist.pod for details. Andy notes that; Alas neither my "Irwin AccuTrack" nor my DC 600A quarter-inch cartridge backup tapes from that era seem to be readable anymore. I guess 13 years exceeds the shelf life for that backup technology :-(. ]
