+@end example
+
+With @option{-tx} option, this command creates @ref{Bundles, bundle} of
+@ref{Encrypted, encrypted packets} from the spool directory and writes
+it to @code{stdout}.
+
+With @option{-rx} option, this command takes bundle from @code{stdin}
+and copies all found packets for our node to the spool directory. Pay
+attention that @strong{no} integrity checking is done by default. Modern
+tape drives could easily provide too much throughput your CPU won't be
+able to verify on the fly. So if you won't @ref{nncp-toss, toss}
+received packets at the place, it is advisable either to run
+@ref{nncp-check} utility for packets integrity verification, or to use
+@option{-check} option to enable on the fly integrity check.
+
+You can specify multiple @option{NODE} arguments, telling for what nodes
+you want to create the stream, or take it from. If no nodes are
+specified for @option{-rx} mode, then all packets aimed at us will be
+processed.
+
+When packets are sent through the stream, they are still kept in the
+spool directory, because there is no assurance that they are transferred
+to the media (media (CD-ROM, tape drive, raw hard drive) can end). If
+you want to forcefully delete them (after they are successfully flushed
+to @code{stdout}) anyway, use @option{-delete} option.
+
+But you can verify produced stream after, by digesting it by yourself
+with @option{-rx} and @option{-delete} options -- in that mode, stream
+packets integrity will be checked and they will be deleted from the
+spool if everything is good. So it is advisable to recheck your streams:
+
+@example
+$ nncp-bundle -tx ALICE BOB WHATEVER | cdrecord -tao -
+$ dd if=/dev/cd0 bs=2048 | nncp-bundle -rx -delete
+@end example
+
+@option{-dryrun} option prevents any writes to the spool. This is

Send @file{SRC} file to remote @option{NODE}. @file{DST} specifies

+taken from @code{stdin}, then you have to have more than 2 GiB of disk space
+for that temporary file and resulting encrypted packet. You can control
+temporary file location directory with @env{TMPDIR} environment

+@url{https://cr.yp.to/chacha.html, ChaCha20}-@url{https://en.wikipedia.org/wiki/Poly1305, Poly1305}
+algorithms. Data is divided on 128 KiB blocks. Each block is encrypted
+with increasing nonce counter. File is deletes immediately after

Perform "tossing" operation on all inbound packets. This is the tool
that decrypts all packets and processes all payload packets in them:
@option{INT} seconds in an infinite loop. That can be useful when
running this command as a daemon.
+@option{-seen} option creates empty @file{XXX.seen} file after
+successful tossing of @file{XXX} packet. @ref{nncp-xfer},
+@ref{nncp-bundle}, @ref{nncp-daemon} and @ref{nncp-call} commands skip
+inbound packets that has been already seen, processed and tossed. This
+is helpful to prevent duplicates.
+
+@option{-nofile}, @option{-nofreq}, @option{-noexec}, @option{-notrns}
+options allow to disable any kind of packet types processing.

Search for directory in @file{DIR} containing inbound packets for us and
move them to local @ref{Spool, spool} directory. Also search for known
neighbours directories and move locally queued outbound packets to them.
This command is used for offline packets transmission.
-If @option{-force} option is specified, then outbound neighbour(s)
+If @option{-mkdir} option is specified, then outbound neighbour(s)
directories will be created. This is useful for the first time usage,
when storage device does not have any directories tree.
@option{-rx} option tells only to move inbound packets addressed to us.
@option{-tx} option tells exactly the opposite: move only outbound packets.

@file{DIR} directory has the following structure:
@file{RECIPIENT/SENDER/PACKET}, where @file{RECIPIENT} is Base32 encoded
destination node, @file{SENDER} is Base32 encoded sender node.

-Remove specified packet (Base32 name) in @option{NODE}'s queues. This
-command is useful when you want to remove the packet that is failing to
-be processed.
