the class BlazeRuntime method newRuntime.

/**
   * Creates a new blaze runtime, given the install and output base directories.
   *
   * <p>Note: This method can and should only be called once per startup, as it also creates the
   * filesystem object that will be used for the runtime. So it should only ever be called from the
   * main method of the Blaze program.
   *
   * @param args Blaze startup options.
   *
   * @return a new BlazeRuntime instance initialized with the given filesystem and directories, and
   *         an error string that, if not null, describes a fatal initialization failure that makes
   *         this runtime unsuitable for real commands
