# =============================================================================
# TASKS
# =============================================================================
# Define tasks that run on all (or only some) of the machines. You can specify
# a role (or set of roles) that each task should be executed on. You can also
# narrow the set of servers to a subset of a role by specifying options, which
# must match the options given for the servers to select (like :primary => true)
