# This module is responsible for encapsulating the logic for
# "disabling" the puppet agent during a run; in other words,
# keeping track of enough state to answer the question
# "has the puppet agent been administratively disabled?"
#
# The implementation involves writing a lockfile with JSON
# contents, and is considered part of the public Puppet API
# because it used by external tools such as mcollective.
#
# For more information, please see docs on the website.
# http://links.puppet.com/agent_lockfiles
