+	  Remote terminal application that supports intermittent
+	  connectivity, allows roaming, and provides speculative local
+	  echo and line editing of user keystrokes.
+
+	  Mosh requires that the remote machine has a locale setting
+	  matching the one on the client.
+
+	  When using mosh with dropbear on a remote machine, the
+	  client needs mosh with a version above 1.3.0 and the
+	  --no-ssh-pty option needs to be passed when starting the
+	  connection.
