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

-bit random key, zero IV, in
-@url{https://en.wikipedia.org/wiki/Counter_mode#Counter_.28CTR.29, CTR}
-mode.
+Encryption is performed with @url{https://cr.yp.to/chacha.html,
+ChaCha20} algorithm. Data is splitted on 128 KiB blocks. Each block is
+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.
