    <p>The module <c>snmp_community_mib</c> implements the instrumentation
    functions for the SNMP-COMMUNITY-MIB, and functions for configuring the 
    database. </p>
    <p>The configuration files are described in the SNMP User's Manual.</p>

        <p>This function is called from the supervisor at system

        <p>Inserts all data in the configuration files into the
          database and destroys all old rows with StorageType
          <c>volatile</c>.  The rows created from the configuration file
          will have StorageType <c>nonVolatile</c>.
          </p>
        <p>All <c>snmp</c> counters are set to zero.
          </p>
        <p>If an error is found in the configuration file, it is
          reported using the function <c>config_err/2</c> of the error,
          report module and the function fails with reason 
          <c>configuration_error</c>.
          </p>
        <p><c>ConfDir</c> is a string which points to the directory
          where the configuration files are found.
