Running scaffolds using the g8 command line tool

[vivek-rao-1985]

I'm trying to run my scaffold using the g8 command line tool, but it seems like there is no option for scaffold -

$ ls .g8/
form
$ g8 scaffold form
Error: Unknown argument 'form'
Try --help for more information.
$ g8 --version
g8 0.16.1

How do I use g8 to run scaffolds that live in the .g8 folder within my project?
