  <modulesummary>Functions for Reporting SNMP Errors through the error_logger</modulesummary>
  <description>
    <p>The module <c>snmpa_error_logger</c> implements the 
      <c>snmpa_error_report</c> behaviour 
      (see <seealso marker="snmpa_error_report">snmpa_error_report</seealso>) 
      containing two callback functions which are called in order to 
      report SNMP errors.
      </p>
    <p>This module provides a simple mechanism for reporting SNMP
      errors. Errors are sent to the <c>error_logger</c> after a 
      size check. Messages are truncated after 1024 chars. 
      It is provided as an example.
      </p>
    <p>This module is the default error report module, but can be 
      explicitly configured, see
      <seealso marker="snmpa_error#desc">snmpa_error</seealso> and
      <seealso marker="snmp_config#configuration_params">configuration parameters</seealso>.

  <funcs>
    <func>
      <name>config_err(Format, Args) -> void()</name>
      <fsummary>Called if a configuration error occurs</fsummary>
      <type>
        <v>Format = string()</v>
        <v>Args = list()</v>
      </type>
      <desc>
        <p>The function is called if an error occurs during the
          configuration phase, for example if a syntax error is found in
          a configuration file.
          </p>
        <p><c>Format</c> and <c>Args</c> are as in
          <c>io:format(Format, Args)</c>.</p>
      </desc>
    </func>
    <func>
      <name>user_err(Format, Args) -> void()</name>
      <fsummary>Called if a user related error occurs</fsummary>

        <v>Format = string()</v>
        <v>Args = list()</v>
      </type>
      <desc>
        <p>The function is called if a user related error occurs at
          run-time, for example if a user defined instrumentation
          function returns erroneous.
          </p>
        <p><c>Format</c> and <c>Args</c> are as in
