"""
The host module contains the objects and method used to
manage a host in Autotest.
The valid actions are:
create: adds host(s)
delete: deletes host(s)
list: lists host(s)
stat: displays host(s) information
mod: modifies host(s)
jobs: lists all jobs that ran on host(s)
The common options are:
-M|--mlist: file containing a list of machines
See topic_common.py for a High Level Design and Algorithm.
