Usage

var supervise = require('lib-supervise');

var job = supervise({
  exec: 'node',
  args: ['server.js']
});

job.on('run', function start(proc) {
  proc.stdout.pipe(process.stdout);
  proc.stderr.pipe(process.stdout);
  console.log("----> job", proc.pid);
});

job.on('die', function fault(code, signal) {
  console.log("----> die", code, signal);
});

job.on('end', function finish() {
  console.log("----> end");

Details

1. supervise always creates pipes to the child process, so you should do something with them
2. child process error events are caught and send to job.error
