40.3 Introduction to Unison
Unison is an excellent solution for synchronizing and transferring entire directory trees.
The synchronization is performed in both directions and can be controlled by means
of an intuitive graphical front-end. A console version can also be used. The synchro-
nization can be automated so interaction with the user is not required, but experience
is necessary.
40.3.1 Requirements
Unison must be installed on the client as well as on the server. In this context, the term
server refers to a second, remote host (unlike CVS, explained in
(page 730)).
In the following section, Unison is used together with ssh. In this case, an SSH client
must be installed on the client and an SSH server must be installed on the server.
