  82       <p>
  83 A helper used by RPC::Agent#implemented_by to delegate an action to an
  84 external script. At present only JSON based serialization is supported in
  85 future ones based on key=val pairs etc will be added
  86 </p>
  87 <p>
  88 It serializes the request object into an input file and creates an empty
  89 output file. It then calls the external command reading the output file at
  90 the end.
  91 </p>
  92 <p>
  93 any STDERR gets logged at error level and any STDOUT gets logged at info
  94 level.
  95 </p>
  96 <p>
  97 It will interpret the exit code from the application the same way <a
  98 href="Reply.html#M000074">RPC::Reply#fail</a>! and fail handles their codes
  99 creating a consistent interface, the message part of the fail message will
 100 come from STDERR
 101 </p>
 102 <p>
 103 Generally externals should just exit with code 1 on failure and print to
 104 STDERR, this is exactly what Perl die() does and translates perfectly to
 105 our model
 106 </p>
 107 <p>
 108 It uses the <a href="../Shell.html">MCollective::Shell</a> wrapper to call
 109 the external application
