PM2 managing arbitrary binaries. Thanks @ravi and pm2 issue #471!

app.json

[{
  "name" : "redis-server",
  "script": "/usr/local/bin/redis-server",
  "instances" : 1,
  "out_file" : "redis-server.log",
  "error_file" : "redis-server.error",
  "exec_interpreter" : "none",
  "exec_mode" : "fork_mode"
}, {
  "name" : "mongod",
  "script": "/usr/local/bin/mongod",
  "args": "['--dbpath=.']",
  "cwd": ".",
  "instances" : 1,
  "out_file" : "mongod.log",
  "error_file" : "mongod.error",
  "exec_interpreter" : "none",
  "exec_mode" : "fork_mode"
}]

PM2 managing arbitrary binaries. In this case, redis and mongodb on OS X. Feel free to modify this if you like. This has been possible since Ravi's PR issue link at Unitech/pm2#471. "cwd" line is shown for gratuitous effect, but is unnecessary. And of course, there are the rest of the options listed at https://github.com/Unitech/pm2/#json-app-declaration

With this, it acts a lot like supervisord, monit, and so on. Just start it with pm2 start app.json. and badda-bing, badda-boom.
