Runs a command using the shell.
Run an external command on the specified DotRepr. Remember to use hSetBinaryMode on the Handle for the output function if necessary. If the command was unsuccessful, then a GraphvizException is thrown. For performance reasons, a temporary file is used to store the generated Dot code. As such, this is only suitable for local commands.
Either calls the given continuation, prints help text and calls exitSuccess, or prints an error and calls exitFailure. See runSubcommand for details on subcommand support.
Run a command within the PlotM monad. Stderr stream is read and decoded, while Stdout is ignored. Logging happens at the debug level if the command succeeds, or at the error level if it does not succeed.
