+# 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 "cloud2.wattsworth.net", user: "rails", roles: %w{app db web}, port: 22
+# server "example.com", user: "deploy", roles: %w{app web}, other_property: :other_value

+set :bundle_without, [:development, :test, :local]
+append :linked_files, "config/database.yml", "config/initializers/smtp.rb"
+
+# 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
+# role :db,  %w{deploy@example.com}
+
+
+
+# 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
+# limited set of options, consult the Net::SSH documentation.
+# http://net-ssh.github.io/net-ssh/classes/Net/SSH.html#method-c-start

+# The server-based syntax can be used to override options:
