+# Definition of mirror hosts we push.
+# One mirror per line, with the following fields defined.
+#
+# ShortName HostName User SSHProtocol SSHKeyFile
+#
+# ShortName will be used as a shorthand in logfile outputs and for the logfile
+# where every ssh output gets redirected to.
+#
+# If no SSHKeyFile is given, the default from the config file applies.
+# If SSHProtocol is empty, it will default to 2, but if you want to
+#                define a keyfile you HAVE TO set protocol too!
+#
+# Example:
+# eu.puccini puccini.debian.org archvsync 2 ~/.ssh/push_puccini
+#
+# will push puccini.debian.org, user archvsync, using ssh protocol 2 and the specified ssh key.
