To specify more sshlogins separate the sshlogins by comma, newline (in
the same string), or repeat the options multiple times.
GNU B<parallel> splits on , (comma) so if your sshlogin contains ,
(comma) you need to replace it with \, or ,,
For examples: see B<--sshloginfile>.
The remote host must have GNU B<parallel> installed.
