View contents of journal
BIND provides a tool called named-journalprint, which which print out the contents of BIND's .jnl files, in a format that is suitable for feeding to nsupdate, for example. Or it can be useful just for seeing what differences BIND has recorded in its journal.
Is there any way to view knot's .diff.db journal files in a similar way to BIND's named-journalprint? If not, could such a tool be added to the knot toolset?
