+NNCP (Node to Node copy) is a collection of utilities simplifying
+secure store-and-forward files and mail exchanging.
+
+This utilities are intended to help build up small size (dozens of
+nodes) ad-hoc friend-to-friend (F2F) statically routed darknet networks
+for fire-and-forget secure reliable files, file requests and Internet
+mail transmission. All packets are integrity checked, end-to-end
+encrypted (E2EE), explicitly authenticated by known participants public
+keys. Onion encryption is applied to relayed packets. Each node acts
+both as a client and server, can use push and poll behaviour model.
+
+Out-of-box offline sneakernet/floppynet, dead drops, sequential and
+append-only CD-ROM/tape storages, air-gapped computers support. But
+online TCP daemon with full-duplex resumable data transmission exists.
