+Send big files with higher nice level! That will guarantee you that
higher priority packets, like mail messages, will pass first, even when
lower priority packet was already been partially downloaded.
There are default niceness levels built-in for @ref{nncp-exec},
@ref{nncp-file} and @ref{nncp-freq} commands. But pay attention that it
can give information about underlying payload to the adversary!
+
+There are 1-255 niceness levels. They could be specified either as
+integer, or using aliases with delta modifiers:
+
+@table @emph
+@item FLASH (F)
+Urgent priority.
+@item PRIORITY (P)
+High priority. Command execution/mail use that priority by default.
+@item NORMAL (N)
+Normal priority. File requests use that priority by default.
+@item BULK (B)
+Bundles shipped on a "least effort" basis. File transmission use that
+priority by default.

+Precedence could be specified both with single-letter aliases and with
+whole strings. They are case insensitive. @emph{MAX} is an alias for 255
+niceness level.
