Show subcommands in help output

[parkr]

• Print custom presentation of command when help switch passed
• Allow subcommands to use --help and --version to show their respective subcommands
• Specs for Mercenary::Presenter

Fixes #15.

@imathis @svnpenn How does this look?

[imathis]

I think it might be a bit verbose. If I want to see what options a subcommand has I can run command subcommand --help right? In that case I like the look of the output when you run git help where it displays "The most commonly use commands".

A list of subcommands followed by description would also be a way to do this.

Not at the moment, which is why I asked.

This sounds sane. :)

[imathis]

Ah, yes. I'd love to be able to scope --help to a subcommand if possible.

Scoped -h and -v as well! Now we have something like:

Aren't we reinventing the wheel here? Can't we just make it look like it was before mercenary?

[parkr]

@svnpenn This entire program is reinventing the wheel. Just better. More circular, more perfect.

Take a look at the travis output for examples.

I dont know how to do that.

@parkr I dig it. However I'd prefer left alignment of subcommands and appropriate padding for descriptions, much like the git help demo above. Right alignment looks nice, but hinders readability.

@imathis New screenshot in the main description above. Thinking we should center options around the , instead of just rjust-ing them. Thoughts?

[imathis]

@parkr Yeah, I'd agree with left justifying options and padding them to center on the , if that's possible.

Jekyll subcommands are for example watch build. I do not see those on the travis page. So I do not see how viewing that page is helpful.

It doesn't contain the Jekyll output – I meant that you can see example output for the commands in the examples.
