"""
The label module contains the objects and methods used to
manage labels in Autotest.
The valid actions are:
add: adds label(s), or hosts to an LABEL
remove: deletes label(s), or hosts from an LABEL
list: lists label(s)
The common options are:
--blist / -B: file containing a list of LABELs
See topic_common.py for a High Level Design and Algorithm.
