"""
Sends an email with a summary report (WIP)
For now, it just sends stdin.
In the future, it will generate a pretty email and send that.
Requires that an SMTP server is configured through environment variables.
Example usage:
$ env OUTPUT_HTML=true python3 examples/working_hours.py | python3 examples/email_report.py
