	Short:       "test config files",
	Long: `
Test config files, without launching V2Ray server.

{{.Exec}} will also use the config directory specified by environment 
variable "v2ray.location.confdir". If no config found, it tries 
to load config from one of below:

	1. The default "config.json" in the current directory
	2. The config file from ENV "v2ray.location.config"
	3. The stdin if all failed above

Arguments:

	-c, -config <file>
		Config file for V2Ray. Multiple assign is accepted.

	-d, -confdir <dir>
		A directory with config files. Multiple assign is accepted.

	-r
		Load confdir recursively.

	-format <format>
		Format of config input. (default "auto")

Examples:

	{{.Exec}} {{.LongName}} -c config.json
	{{.Exec}} {{.LongName}} -d path/to/dir

Use "{{.Exec}} help format-loader" for more information about format.
