+zsync is a file transfer program. It allows you to download a file from
+a remote web server, where you have a copy of an older version of the
+file on your computer already. zsync downloads only the new parts of the
+file. It uses the same algorithm as rsync.
+
+zsync does not require any special server software or a shell account on
+the remote system (rsync, in comparison, requires that you have an rsh
+or ssh account, or that the remote system runs rsyncd). Instead, it uses
+a control file - a .zsync file - that describes the file to be
+downloaded and enables zsync to work out which blocks it needs. This
+file can be created by the admin of the web server hosting the download,
+and placed alongside the file to download - it is generated once, then
+any downloaders with zsync can use it. Alternatively, anyone can
+download the file, make a .zsync and provide it to other users (this is
+what I am doing for the moment).
