A few suggestions and reference to another issue

[IotaSpencer]

In reference to #553

I'd like to see something like this, as well as an easier way to implement version commands, considering currently, you have to make a __version method and map it, which is a bit inconvenient.
If you could do

class App < Thor
  version Library::VERSION
  desc '...', '...'
  def command(arg1, arg2)
    # ...
  end 
end

In regards to other suggestions

I do like the mapping feature as it allows me to make debugging options, like --gem-info or things of that nature that are a command in a sense but are better marked and input as an option in the whole grand scheme of things.
GLI itself, which I have been using for a while, it has been good, but I find thor to be a better kept library, a couple things GLI does have that I'd like to see in thor would be,

• version -- As I have said
• pre_command, post_command, around_command hooks -- This would help with Configuration files and state keeping for larger projects
  • Yes you could run a configuration setup before each command code, but that tends to make the state keeping a bit messy, as, if thor had a pre or around hook, I could #initialize or load my configuration once in the whole process and use hooks that they have implemented to reload configuration on the fly.

I'll add more to this as I can think of things.
