}This one needs environment variables set before it will start:
BACKBURNER_HOME (Directory for the task database and log files (default: ~/.backburner)), BACKBURNER_ALLOW (Comma-separated regexes; if set, only matching commands may run), BACKBURNER_DENY (Comma-separated regexes; matching commands are always refused (deny wins over allow)).
