I was hoping somebody would just cook up a patch based on augtool ;) It shouldn't be much more work than doing it (yet again) for standalone use.
I can try to do it. To be clear, the task is to add method to augeas library called e.g. batch, which takes string argument. In this argument will be command (or semicolon separated list of commands) same as for augtool. What will the method return? True only if all commands succeeds, false otherwise?
