  <description>
    <p>The module <c>snmp_framework_mib</c> implements instrumentation
      functions for the
      SNMP-FRAMEWORK-MIB, and functions for initializing and configuring the
      database.
      </p>
    <p>The configuration files are described in the SNMP User's Manual.</p>
  </description>
  <funcs>
    <func>
      <name>configure(ConfDir) -> void()</name>
      <fsummary>Configure the SNMP-FRAMEWORK-MIB</fsummary>
      <type>
        <v>ConfDir = string()</v>
      </type>
      <desc>
        <p>This function is called from the supervisor at system
          start-up.
          </p>
        <p>Inserts all data in the configuration files into the
          database and destroys all old data.
          </p>
        <p>Thus, the data in the SNMP-FRAMEWORK-MIB, after this
          function has been called, is from the configuration
          files.
          </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.
          </p>
        <p>The configuration file read is: <c>context.conf</c>.

          exist. It does not destroy any old values.
