Might be good to have some logging statements early on, with --dryrun, or in a verbose/debug mode:
e.g.

Reading config from <config-toml>
    found N job parameters
    found N command placeholders
    Using N modules statements
Reading job parameters from <profile csv>
    Found N columns (parameters) and M rows (jobs)
Beginning job preperation and submission...
    Preparing directory for row (job) 1
    Submitted job 1, jobID: <jobid>
    Preparing directory for row (job) 2
    Submitted job 2, jobID: <jobid>
