Help flag

[bpsizemore]

No help flag available from the CLI. Can't expect people to continually reference the github docs.
Any reason not to do this? If not I'll look at it and put in a PR this weekend.

As you pointed out, it's a must. I simply didn't have time to do that.

I'll look at it and put in a PR this weekend.

PR is appreciated, thanks!
