+Description
+~~~~~~~~~~~
+
+This command displays the borg client version / borg server version.
+
+If a local repo is given, the client code directly accesses the repository,
+thus we show the client version also as the server version.
+
+If a remote repo is given (e.g. ssh:), the remote borg is queried and
+its version is displayed as the server version.
+
+Examples::
+
+    # local repo (client uses 1.4.0 alpha version)
+    $ borg version /mnt/backup
+    1.4.0a / 1.4.0a
+
+    # remote repo (client uses 1.4.0 alpha, server uses 1.2.7 release)
+    $ borg version ssh://borg@borgbackup:repo
+    1.4.0a / 1.2.7
+
+Due to the version tuple format used in borg client/server negotiation, only
+a simplified version is displayed (as provided by borg.version.format_version).
+
+There is also borg --version to display a potentially more precise client version.
