+# 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 "train.nzoi.org.nz", user: "cap_deploy", roles: %w[app db web]

+
+# 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.

+
+# 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.
