Generating cookbook unicorn

- Ensuring delivery configuration
- Ensuring correct delivery build cookbook content
Your cookbook is ready. Type `cd unicorn` to enter it.
There are several commands you can run to get started locally developing and testing your cookbook.
Type `delivery local --help` to see a full list.
Why not start by writing a test? Tests for the default recipe are stored at:
test/smoke/default/default_test.rb
If you'd prefer to dive right in, the default recipe can be found at:
recipes/default.rb
template作成
$ chef generate template site-cookbooks/unicorn unicorn_app
Recipe: code_generator::template
* directory[site-cookbooks/unicorn/templates] action create
- create new directory site-cookbooks/unicorn/templates
* template[site-cookbooks/unicorn/templates/unicorn_app.erb] action create
