Hi, I noticed that the command line tools could use a little love. For instance, I was surprised that most of them don't support `--help`, and generally there are a few inconsistencies.
KIP-14 is dormant and AFAICS no one is working on https://issues.apache.org/jira/browse/KAFKA-2111 either. So if I'm not treading on anyone's toes, I would like to improve this situation. Specifically I propose to: 1. Add support for `--help` for all tools with shell scripts. 2. Include in the help output on non-Windows systems documentation for the script-implemented `--daemon`, `--name` and `--loggc` options, because currently they're not very discoverable. 3. Add more standard equivalents for non-UNIXish options (e.g. add `--consumer-config` as well as `--consumer.config`). I also noticed that overall Kafka has two option parsing dependencies: `argparse4j` and `jopt-simple`. Is there a good reason for this? If not then I could standardize on one at the same time. Would this require a KIP? If so should I open a new one, or resurrect KIP-14? Regards, Tom
