@end example

Perform @ref{Spool, spool} directory integrity check. Read all files
that has Base32-encoded filenames and compare it with recalculated
@ref{MTH} hash output of their contents.

The most useful mode of operation is with @option{-nock} option, that
checks integrity of @file{.nock} files, renaming them to ordinary
(verified) encrypted packets.

@option{-cycle} option tells not to quit, but to repeat checking every
@option{INT} seconds in an infinite loop. That can be useful when
running this command as a daemon.
