    DESCRIPTION
        "This is a MIB for a distributed OTP system, with one SNMP
        agent executing at one node only.  Each Erlang node in the
        OTP system is represented by one row in the erlNodeTable."

    REVISION        "201307160700Z"
    DESCRIPTION
        "Updated various types to be able to reflect larger values.
        The objects erlNodeReductions, erlNodeInBytes, erlNodeOutBytes as well
        as the type MilliSeconds have been updated to Counter64."

    REVISION        "200305090900Z"
    DESCRIPTION
        "Changed CONTACT-INFO as it was outdated, made it more generic
	to avoid such changes in the future."
    
    REVISION        "199712010900Z"
    DESCRIPTION
        "Converted to v2 SMI and placed in the OTP tree."
