Entry point for application

Features

  1. Support environment configs with dependencies. Each yaml config file may contain depends key to preload configs from parent environment config files
  2. Support argument customization via config You can define your own flags parsed automatically on application starts
  3. Support processing commands through socket connection You can define your own command passed through socket connection. Command implementation
  4. Logger interface Minimal function set for basic logger
  5. Standard application instance (DNApp) out of the box.
