 - `exeflags`: An array of strings which are appended to the `julia` command that starts the worker process. For example, a notebook is run with `--project=@.` by default (the environment in the directory where the notebook is stored) but this could be overridden by setting `exeflags: ["--project=/some/directory/"]`.
 - `env`: An array of strings where each string specifies one environment variable that is passed to the worker process. For example, `env: ["SOMEVAR=SOMEVALUE"]`.
