WARNING! 

Clef is alpha software, and not yet publically released. This software has _not_ been audited, and there
are no guarantees about the workings of this software. It may contain severe flaws. You should not use this software
unless you agree to take full responsibility for doing so, and know what you are doing. 

TLDR; THIS IS NOT PRODUCTION-READY SOFTWARE!
