Process only single specified node.

Print only errors, omit simple informational messages. In any case
those messages are logged, so you can reread them using

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

taken from stdin, then you have to have 2 GiB of disk space for that
temporary file and resulting encrypted packet. You can control where
temporary file will be stored using @env{TMPDIR} environment variable.
-Encryption is performed with

-mode.
+Encryption is performed with @url{https://cr.yp.to/chacha.html,

+encrypted with increasing nonce counter.
If @option{-chunked} is specified, then source file will be split
@ref{Chunked, on chunks}. @option{INT} is the desired chunk size in

-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.
+This command is aimed to delete various files from your spool directory:
+
+@itemize
+@item If @option{-tmp} option is specified, then it will delete all
+temporary files in @file{spool/tmp} directory. Files may stay in it when
+commands like @ref{nncp-file} fail for some reason.
+@item If @option{-lock} option is specified, then all @file{.lock} files
+will be deleted in your spool directory.
+@item If @option{-pkt} option is specified, then @file{PKT} packet (its
+Base32 name) will be deleted. This is useful when you see some packet
+failing to be processed.
+@item When either @option{-rx} or @option{-tx} options are specified
+(maybe both of them), then delete all packets from that given queues. If
+@option{-part} is given, then delete only @file{.part}ly downloaded
+ones. If @option{-seen} option is specified, then delete only
+@file{.seen} files.

Perform "tossing" operation on all inbound packets. This is the tool
@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} and
+@ref{nncp-bundle} commands skip inbound packets that has been already
+seen, processed and tossed. This is helpful to defeat duplicates.

@node nncp-xfer
@section nncp-xfer
@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.
+
+Also look for @ref{nncp-bundle}, especially if you deal with CD-ROM and
+tape drives.
