A transformer is a receiving interface for a jobspec. It ensures that the work can be staged, with any additional steps (at the jurisdiction of the transformer) to be performed. This basic demo shows the flux transformer receiving the job, setting up a staging directory, writing a script, and submitting it, both in a wait (watch) mode and without. Other example transformers might be for a Kubernetes cluster, Google Batch, or AWS Batch, or even my local machine.
