If you want to use specific SSH options, make sure to edit the script
and set SSH_OPTS variable correctly. Beware that there are several SSH
calls and one SCP call for which these options are used as well,
so you must choose arguments format that works with both programs. For
example, if you want to use a different port, you can't use "-p 2222",
because that works for SSH but not for SCP (for scp it's equivalent
argument is -P - capital P). It's best to use -o ssh_option=value format
that works with both programs, for example "-o Port=2222"
