var RootCmd = &cobra.Command{
	Use:   os.Args[0],
	Short: "Secure File Sharing for business",
	Long: `Thank you for using Pydio Cells.
Comprehensive sync & share solution for your collaborators. Open-source software deployed on-premise or in a private cloud.

### Installation

For the very first run, use '` + os.Args[0] + ` install' to load browser-based or command-line based installation wizard. Services
will start at the end of the installation.

### Run

Run '` + os.Args[0] + ` start' to load all services.

### Logs level

By default, logs are outputted in console format at the Info level. You can set the --log flag or set the PYDIO_LOGS_LEVEL environment
variable to one of the following values:
 - debug, info, error : logs are written in console format with the according level
 - production : logs are written in json format, for usage with a log aggregator tool.

### Services Discovery

Micro services need a registry mechanism to discover each other. You don't need to install any dependency.
Cells currently only supports NATS (nats.io) implementation. If a gnatsd service is already running, it will be detected.

### Cells working directories

By default, application data is stored under the standard OS application dir : 

 - Linux: ${USER_HOME}/.config/pydio/cells
 - Darwin: ${USER_HOME}/Library/Application Support/Pydio/cells
 - Windows: ${USER_HOME}/ApplicationData/Roaming/Pydio/cells

You can customize the various storage locations with the following ENV variables : 

 - CELLS_WORKING_DIR : replace the whole standard application dir
 - CELLS_DATA_DIR : replace the location for storing default datasources (default CELLS_WORKING_DIR/data)
 - CELLS_LOG_DIR : replace the location for storing logs (default CELLS_WORKING_DIR/logs)
 - CELLS_SERVICES_DIR : replace location for services-specific data (default CELLS_WORKING_DIR/services)

RootCmd represents the base command when called without any subcommands

var StartCmd = &cobra.Command{
	Use:   "start",
	Short: "Start Cells services",
	Long: `Start one or more services on this machine

### Syntax

$ ` + os.Args[0] + ` start [flags] args...

Additional arguments are regexp that can match any of the service names available (see 'list' command).
The -t/--tags flag may limit to only a certain category of services, use lowercase like broker, idm, data, etc...
The -x/--exclude flag may exclude one or more services
Both flags may be used in conjunction with the regexp arguments.

### Examples

Start only services starting with grpc
$ ` + os.Args[0] + ` start pydio.grpc

Start only services for scheduler
$ ` + os.Args[0] + ` start --tag=scheduler

Start whole plateform except the roles service
$ ` + os.Args[0] + ` start --exclude=pydio.grpc.idm.roles

StartCmd represents the start command

Functions

func Execute

func Execute()

Execute adds all child commands to the root command and sets flags appropriately. This is called by main.main(). It only needs to happen once to the rootCmd.
