        This package contains a C "interpreter". Behind the scenes it actually
        compiles the file and runs it immediately, so it's not really an
        interpreter. Point is, it allows you to use a shebang (just like
        `#!/bin/sh`) to write C programs that execute like a Bash scripts.
