ZDBUTIL converts ZDB databases from the old to the new 
format, and displays, prints and outputs ascii text 
given a new format ZDB database. After converting to the new 
format, sort the database to delete a dummy deleted record 
created during the conversion process. Version 1.5 detects a 
command tail and has a smarter user interface. Written by
