cancel-my-jobs

#!/bin/bash
#
#  cancel-my-jobs
#
#  Delete all jobs belonging to a user (including running jobs).
#
#  Usage:
#    cancel-my-jobs [--help]
#
#  Possible future enhancements:
#    - Rewrite in Python for better argument parsing and security.
#    - Add "--dry-run|-n" option to only show what would be done, not do it.
#    - Add "--running" option to only delete running jobs.
#    - Add "--not-running" option to delete jobs which are not yet running.
