"[A] Unix multitool that runs on Windows and Minoca OS. It is a single binary that contains many of the basic core POSIX utilities, including a Bourne shell (sh), cp, mv, sed, and many more. No installation is necessary. The entire release is a single executable, and it makes no registry changes. Simply run swiss or swiss sh to fire up a shell. The swiss sh shell knows how to execute the other applications built into the binary. To specialize swiss into a particular utility, simply rename swiss.exe to that utility. For instance, copy swiss.exe to sed.exe, and it will always act directly as sed when run."
