	Name:    "sync",
	Usage:   "Ensure recipe version labels are up-to-date",
	Aliases: []string{"s"},
	Description: `
This command will generate labels for the main recipe service (i.e. the service
named "app", by convention) which corresponds to the following format:

    coop-cloud.${STACK_NAME}.version=${RECIPE_TAG}

The ${RECIPE_TAG} is determined by the recipe maintainer and is retrieved by
this command by asking for the list of git tags on the local git repository.
The <recipe> configuration will be updated on the local file system.
