 ## Status
 
 `shed` is experimental software and is currently under active development. It covers most day-to-day interactive shell usage and a good portion of POSIX shell scripting, but it is not yet fully POSIX-compliant. There is no guarantee that your computer will not explode when you run this. Use it at your own risk, the software is provided as-is.
