Version 1.4.0
    D.Urist, P.Holzleitner

    Implemented extended SNMP options per Dan's suggestions.
    (Config file only to avoid commandline option conflicts)
    

Version 1.3.0
    Dave Alden, P.Holzleitner

    Permit non-integer limit values (e.g. 2.5)

    Added DefaultMin/DefaultMax/DefaultMinVal/DefaultMaxVal options
    so that common limits can be specified in the .def file.

    Added variable-group concept.  Useful e.g. for monitoring one host's
    variables at different intervals (1 min for port up/down, 15 min for
    temperatures, ...)
    
    A default group can be assigned in the .def file, or specified/overriden
    individually per (host,oid) in the .cf file.

    Groups are optional.  Without --groups= option on the command line,
    all variables are checked as in previous versions.

    One or more Groups can be specified for inclusion or exclusion:

      --groups=Power        only vars in the Power group
      --groups=Power,Env    vars in the Power or Env group
      --groups=-Power,-Env  all vars except those in Power or Env groups
      --groups=Power,-Env   won't work (only the exclusions are recognized)

    
    
Version 1.2.0
    P.Holzleitner

    Added ability to replace array entries with friendly names,
    e.g. "Engineering Ethernet" instead of "Port Status [3]"
    
    
Version 1.1.2
    P.Holzleitner

    Fixed -l output with plausibility checks
    
    
Version 1.1.1
    P.Holzleitner

    Automatically append the previously required trailing dot
    on OIDs that are indexed.
    
    
Version 1.1.0
    P.Holzleitner
    
    Configurable upper and lower plausibility limits added for agents
    that occasionally report an off-scale reading, e.g. 1200 amps
    current on the +5V supply ;-)
    
       PE4300_PSU1_5V_CURRENT      Max 25  MaxValid 100  MinValid -1

    This would cause snmpvar.monitor to ignore readings below -1 or
    above 100 for this variable and NOT signal an error.
    
    However, it writes a message to syslog.
    

Version 1.0.1
    P.Holzleitner
    
    Fixed a bug in reading Decode definitions where only the
    first digit of the value would be picked up
