Note About Antivirus False Positives:

There is a chance that your antivirus will detect threats if you try and run the binary files, specifically something called Trojan:Win32/Wacatac.H!ml whatever that is. If this happens to you, either tell your antivirus to shut up somehow, or just download the source code and compile locally with sh release.sh. I promise this program is not a virus.
