-"""Low-level text dumps of FileStorage contents.
-
-fsdump() prints a two-line summary of each transaction and a one-line
-summary of each data record in that transaction.  This report is often
-useful when analyzing a storage's contents.
-
-Dumper() prints a very detailed representation of the contents.  Each
-header field is printed on a separate line.  This produces lots of
-data that is useful when debugging the storage implementation.
