directory. @strong{log} field contains an absolute path to @ref{Log,

+Non-empty optional @strong{umask} will force all invoked commands to
+override their umask to specified octal mask. Useful for using with

+Enabled @strong{noprogress} option disabled progress showing for many

@anchor{CfgNotify}
@strong{notify} section contains notification settings for successfully
-tossed file and freq packets. Corresponding @strong{from} and
+tossed file, freq and exec packets. Corresponding @strong{from} and
@strong{to} fields will be substituted in notification email message.

corresponding notifications, or the whole section at once.
+@code{notify.exec} section is a mapping of exec handles and
+corresponding @code{from}/@code{to} sections. Each handle has either
+@code{NODE.HANDLE} or @code{*.HANDLE} syntax. You can override
+notification options for some node with the first type of name.
+Handle command's output will be included in notification messages.

@strong{self} section contains our node's private keypairs.
@strong{exch*} and @strong{sign*} are used during @ref{Encrypted,
encrypted} packet creation. @strong{noise*} are used during @ref{Sync,
data (public keys). It is useful for copy-paste sharing with your
friends. Each section's key is a human-readable name of the neighbour.

@anchor{CfgIncoming}
@item incoming
Full path to directory where all file uploads will be saved. May be
omitted to forbid file uploading on that node.
@anchor{CfgFreq}
-@item freq
+@item freq.path
Full path to directory from where file requests will queue files for
transmission. May be omitted to forbid freqing from that node.
-@item freqchunked
+@item freq.chunked
If set, then enable @ref{Chunked, chunked} file transmission during
freqing. This is the desired chunk size in KiBs.

+@item freq.minsize
If set, then apply @ref{OptMinSize, -minsize} option during file
transmission.
@anchor{CfgVia}
@item via
An array of node identifiers that will be used as a relay to that node.
-For example @verb{|[foo,bar]|} means that packet can reach current node
-by transitioning through @emph{foo} and then @emph{bar} nodes. May be
-omitted if direct connection exists and no relaying is required.

+node by transitioning through @code{foo} and then @code{bar} nodes. May
+be omitted if direct connection exists and no relaying is required.
@anchor{CfgAddrs}
@item addrs
Dictionary containing known network addresses of the node. Each key is
-human-readable name of the link/address. Values are @verb{|addr:port|}
-pairs pointing to @ref{nncp-daemon}'s listening instance. May be omitted
-if either no direct connection exists, or @ref{nncp-call} is used with

+@verb{|host:port|} format, pointing to @ref{nncp-daemon}'s listening
+instance. Also you can pipe connection through the external command
+using @verb{#|some command#} format. @code{/bin/sh -c "some command"}
+will start and its stdin/stdout used as a connection. May be omitted if

@ref{nncp-caller} won't be used to call that node.
