- [`Flag() *config.Config`](http://godoc.org/github.com/olebedev/config#Config.Flag) method, for command line arguments parsing usign pkg/flag singleton
- [`Args(args ...string) *config.Config`](http://godoc.org/github.com/olebedev/config#Config.Args) method, for command line arguments parsing
- [`U*`](https://godoc.org/github.com/olebedev/config#Config.UBool) methods
- [`Copy(...path) (*config.config, error)`](https://godoc.org/github.com/olebedev/config#Config.Copy) method
- [`Extend(*config.Config) (*config.Config, error)`](https://godoc.org/github.com/olebedev/config#Config.Extend) method
