var RootCmd = &cobra.Command{
	Use:   "terracanary",
	Short: "Deployment orchestration using terraform",
	Long:  `Terracanary provides a wrapper for terraform that manages multiple versions of terraform stacks and facilitates sharing data between multiple related stacks. This allows you to easily construct complex deployment procedures.`,
	Example: `# Apply database infrastructure updates
terracanary apply --stack database
# Run database migrations
...
# Build new copy of infrastructure, using shared database
NEW_VERSION=$(terracanary next)
terracanary apply --stack-version main:$NEW_VERSION --input-stack database
# Run some automated tests on new main stack
HOSTNAME_TO_TEST=$(terracanary output --stack-version main:$NEW_VERSION hostname)
...
# Start sending traffic to new main stack
terracanary apply --stack routing --input-stack-version main:$NEW_VERSION
# Clean up old stack(s)
terracanary destroy --all main --except main:$NEW_VERSION`,
