+                      ncp - a fast file copy tool for LANs
+
+(Note: This is from 2000 and has not been touched since. I still use it on a
+daily basis)
+
+Download it from http://dl.fefe.de/ncp-1.2.4.tar.bz2 [pgp sig]! The current
+version is 1.2.4. Recent changes: switch to libowfat
+
+Good news: I got an email from Ripclaw from Rock Linux who told me that they are
+going to integrate ncp.
+
+Please note that on recent IPv6 implementations, link-local addresses are not
+valid without specifying an interface, so you can't npoll with a link-local
+address on the command line. Standard npush/npoll now works with link-local
+addresses, though. Due to Linux 2.4.0test brokenness, you currently can't npoll
+from the same machine that runs npush.
+
+Since ncp is based on libdjb, it features full IPv6 support and the DNS resolver
+is built in, i.e. no more security problems because of lame libc functions.
+
+I also provide a statically linked x86 Linux binary [sig] compressed with upx
+which only weighs in at ~20k. I shrunk the binary with diet libc.
+
+npush will now use IPv6 and IPv4 multicast on the multicast groups
+ff02::6e63:7030 (6e63:7030 == 'ncp0') and 224.110.99.112 (110.99.112 == 'ncp').
+If both methods fail, npush will resort to the broadcast packets used by
+previous versions. You can force the broadcast method by passing "-b" to npush
+so that previous npoll versions can see the announcements.
+
+"ncp" is a utility for copying files in a LAN. It has absolutely no security or
+integrity checking, no throttling, no features, except one: you don't have to
+type the coordinates of your peer.
+
+Please note that the DNS resolver does not use /etc/hosts (as that would not
+work with IPv6 anyway), so you should have a properly configured DNS server.
+
+Basically it works like this:
+ 1. You and your buddy want to play Quake
+ 2. Your buddy has a level that you don't have
+ 3. He types npush filename and waits. npush sends out UDP announcement packets
+    proclaiming that someone wants to send something
+ 4. You type npoll. npoll waits until it sees one of these packets
+ 5. The files are copied with tar over a TCP socket, so permissions and file
+    dates (and if you are root, owners) are preserved.
+
+There are other usage modes. You can also use it like this:
+
+  peer1$ ncp
+                           peer2$ ncp peer1 file1 file2 file3
+
+or like this:
+
+  peer1$ npush file1
+                           peer2$ npoll peer1
