Support version and help commands #52

Closed domn1995 closed 4 years ago

domn1995 commented 4 years ago

Many CLI tools have built-in version and help commands. For example:

>git version
git version 2.9.2.windows1

>git help
usage: git [...]
...

Are we interested in supporting this in CliFx?
Also, if supporting help as a builtin command, do we want it only for the root of the app or to all subcommands? I propose all subcommands.
For the builtin 'version` command, I think it would only make sense to be built in to the root of the app.

No, I want to avoid adding too many ways of doing the same thing, since we already have the help and version options already. When I started the project design, I was debating whether to use the options or the commands for this, but I've settled on the options as it was more common in my experience.
