How to cleanly deploy the roots theme?

First of all, I’m sorry for the newbie question. I just start using Roots for developing a theme. Everything is going well with varieties of tools provided by Roots. However, I don’t really know how to cleanly deploy it to forest theme; build only files needed for a theme.

Is there any grunt command used to create a separate dist folder that is only composed of theme files ? or Could you please suggest me how to cleanly deploy it?

Thanks in advance!
