Feature Request - Improved Documentation With Help Output

[Sn3akyP3t3]

I'm not finding an easy way to get the --help output to include some basic information including details about the arguments. It seems to just parse the function signature and reflects on that only. Maybe I'm just not assembling the function's documentation correctly. Either way I found little to no examples in the online documentation explaining how --help is can be used in this way as well as no existing examples in the source code's examples directory showing this. I'm not sure if this is possible, but it would be nice to know how to improve the --help output so its not missing details.

Here's an example that I put together with a function description and information for the args as to how they should display with --help output.

See issue #259 which does give more help info on function args
