+# This is the ssh client system-wide configuration file.  See
+# ssh_config(5) for more information.  This file provides defaults for
+# users, and the values can be changed in per-user configuration files
+# or on the command line.
+
+# Configuration data is parsed as follows:
+#  1. command line options
+#  2. user-specific file
+#  3. system-wide file
+# Any configuration value is only changed the first time it is set.
+# Thus, host-specific definitions should be at the beginning of the
+# configuration file, and defaults at the end.
+
+# Site-wide defaults for some commonly used options.  For a comprehensive
+# list of available options, their meanings and defaults, please see the
+# ssh_config(5) man page.
