| 44 | babeltrace ... --params='many=null, fresh=yes, condition=false, | |
| 45 | squirrel=-782329, observe=3.14, | |
| 46 | simple=beef, needs-quotes="some string", | |

| 51 | IMPORTANT: Like in the example above, make sure to single-quote the | |
| 52 | whole argument when you run this command from a shell. |
