-# server-based syntax
-# ======================
-# Defines a single server with a list of roles and multiple properties.
-# You can define all roles on a single server, or split them:
-
-# server 'example.com', user: 'deploy', roles: %w{app db web}, my_property: :my_value
-# server 'example.com', user: 'deploy', roles: %w{app web}, other_property: :other_value
-# server 'db.example.com', user: 'deploy', roles: %w{db}
-
-
-
-# role-based syntax
-# ==================
-
-# Defines a role with one or multiple servers. The primary server in each
-# group is considered to be the first unless any  hosts have the primary
-# property set. Specify the username and a domain or IP for the server.
-# Don't use `:all`, it's a meta role.
-
-# role :app, %w{deploy@example.com}, my_property: :my_value
-# role :web, %w{user1@primary.com user2@additional.com}, other_property: :other_value

-# Configuration
-# =============
-# You can set any configuration variable like in config/deploy.rb
-# These variables are then only loaded and set in this stage.
-# For available Capistrano configuration variables see the documentation page.
-# http://capistranorb.com/documentation/getting-started/configuration/
-# Feel free to add new variables to customise your setup.

-# Custom SSH Options
-# ==================
-# You may pass any option but keep in mind that net/ssh understands a
