Runs a command using the shell.
Run a Command.
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.
Execute a Command.
Given a list of command/action pairs, prompt the user to choose a command using dmenu and return the corresponding action.
