+# This script is a workaround for the key collision issue when loging into
+# onos cli from both test-station and onos cells with identical user names.
+# It copies both private and public keys of localhost (test-station) to
+# all remote hosts specified in your cell.
+# It also backs up the original keys of the remote hosts before
+# overwriting them.
+# Setting up passwordless login is recommended before running the script.
