    """Add directive `run-command` that enhances `command-output` by proper usage
        of the build directory. It is used just the same as `command-output`:

        .. run-command:: <command>
            :cwd: /directory
        
        The only difference to `command-output` is that the current working directory
        defaults to the current build folder, and the directory (optionally) given
        to the `cwd` option allows for the following placeholders:

        - `<build>`: current build folder

        The path of the build folder needs to be configured in the `runcmd_build` option.
