#
#       1.   command-line options
#       2.   user's configuration file (~/.ssh/config)
#       3.   system-wide configuration file (/etc/ssh/ssh_config)
#
# For each parameter, the first obtained value will be used.  The configuration files contain sections separated
# by “Host” specifications, and that section is only applied for hosts that match one of the patterns given in the
# specification.  The matched host name is the one given on the command line.
