Is FAILED considered to be 'I was able to run the command, but it returned an error code', versus ERROR being 'I could not even run the command!' like bad path, file not found, etc... This point still kind of confuses me (and needs to be well defined). I am an advocate of having three distinct messages: OK, SKIPPED, ERROR. And not even bothering with the different types of ERROR/FAILED other than having extra reporting output. Of course, I am still willing to implement what the consensus is. -- Coleman Kane
