Install a service

var service = {
  domain: 'user',
  plist: {
    Label: 'fake',
    ProgramArguments: [
      '/Users/vagrant/node/node-v5.9.1-darwin-x64/bin/node',
      '/Users/vagrant/wd/utils/fake-service.js'
    ]
  }
}
lsa.install(service, function (err, results) {
  err && console.error(err);
  var serviceFile = '/Users/vagrant/Library/LaunchAgents/fake.plist';
  fs.readFile(serviceFile, function (err2, content){
    err2 && console.error(err2);
    console.log(content.toString())
  })
})

// find the corresponding service file, then deletes it
lsa.uninstall('fake', function (err, results) {
  err && console.error(err);
})

// deletes given service file definition
lsa.uninstallUnitFile('/Users/vagrant/Library/LaunchAgents/fake.plist', function (err, results) {
