$ nncp-check [-nock] [-cycle INT] [options]
Perform spool directory integrity check. Read all files that has Base32-encoded filenames and compare it with recalculated Merkle Tree Hashing hash output of their contents.
The most useful mode of operation is with -nock option, that checks integrity of .nock files, renaming them to ordinary (verified) encrypted packets.
-cycle option tells not to quit, but to repeat checking every INT seconds in an infinite loop. That can be useful when running this command as a daemon.
