Command should print out usage information

[wkoszek]

I've installed a gitlab Gem, but the gitlab help isn't very helpful. I need to read a README.md from this repo to understand how to use it. I think gitlab help should print out a standard UNIX usage information with some examples.

@wkoszek any example?

I think it should be like in man hub https://github.com/github/hub/blob/70a5493539d7a614449f0d32051e08b0dbc53bc3/share/man/man1/hub.1.ronn

@NARKOZ Right. Instead of just listing options, show 20 simple one-liners with explanations on what they do. hub, awk, jq and other commands will give you an idea. Thanks!
