namespace Star {
// Parses command line flags and loads and returns the Root singleton based on
// them.
//
// It is designed to load settings first from the settings passed into the
// constructor, then from the required boot config file , then from any passed
// in command line flags. Besides -version, the accepted command line flags
// are:
//
// -bootconfig <bootconfig> - sets path to the boot configuration file, defaults to sbinit.config
// -logfile <logfile> - sets path to logfile, if any, relative to root storage directory
// -loglevel <level> - sets logging level
// -quiet - turns off stdout logging
// -verbose - turns on stdout logging
// -runtimeconfig - sets the path to the runtime configuration storage file, relative to root storage directory
//
// The boot config file can contain the following options:
// 'assetDirectories' - Asset source search directories
// 'logFileBackups' - Number of rotated backups of the target log file
// 'storageDirectory' - Primary Root storage directory
// 'assetsSettings' - Merged with base assets settings
// 'defaultConfiguration' - Merged with base default configuration
