    As James pointed out, there are 3 fan control applications where 2 are 
    currently maintained repos.
    
    obmc-control-fan_git.bb & obmc-phosphor-fand.bb
    To my knowledge, these were the fan management reference implementations 
    that are no longer maintained and/or supported.
    
    https://github.com/openbmc/phosphor-pid-control
    (This is a configurable PID based fan control application)
    
    https://github.com/openbmc/phosphor-fan-presence
    (This contains configurable fan presence, fan monitoring, and RPM/PWM 
    fan control applications)
    
    The doc draft that George referenced relates to the 
    phosphor-fan-presence repo.
