Jason Warner updated GSHELL-66:
-------------------------------

    Attachment: GShell-66.patch

I added some code to printUsage to generate the appropriate lists and syntax command only
if those pieces were present.  I'm not attached to the wording or format, so if you feel like
tweaking those go right ahead.

> When generating a commands --help, the syntax/usage should be auto-generated.
> For example take the {{help}} command's {{--help}}:
> {noformat}
> jason@Bliss.local:/> help --help
> help
>  -- 
>   VAL            Command name
>   -h (--help)    Display this help message
