# have statuses (prefixed with `-----> `), errors (prefixed with `! `),
# commands (prefixed with `$ `) or anything else. Depending on the type of
# the message, they will be delegated to the proper print_* helper.

# -----> Unlocking
# $ unlock foo
# Unlocked.
# ! ERROR: Failed

# Returns nothing.
