Metadata is supported in the config file on a per-task basis. It is to be put
in the 'meta' key's value json.
Currently 'title' and 'description' keys are supported. See the example below.
```
[
{
"meta" : {
"title" : "This is the title",
"description" : "This is a longer description, not shown with -Q"
}
}
]
```
