"""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.
