-Sent acknowledgement of successful @option{PKT} (Base32-encoded hash)
-packet receipt. If @option{rx} is specified instead, then all
-@option{NODE}'s existing @code{rx} packets will be acknowledged.
+Send acknowledgement of successful @option{PKT} (Base32-encoded hash)
+packet receipt from @option{NODE} node. If no @option{-pkt} is
+specified, then acknowledge all packet in node's @code{rx} outbound
+spool. If @option{-all} is specified, then do that for all nodes.
General workflow with acknowledgement is following, assuming that
Alice has some outbound packets for Bob:
@itemize
-@item Transfer an encrypted packets, without deleting them locally:
+@item Transfer encrypted packets, without deleting them locally:
@example
alice$ nncp-xfer -keep -tx -node bob /mnt/shared
@item Create ACK packets of received ones:
@example
-bob$ nncp-ack alice rx
+bob$ nncp-ack -node alice
@end example
@item Send those newly created packets back to Alice:
