The Sync Framework 4.0 CTP documentation on MSDN library (http://msdn.microsoft.com/en-us/library/gg299051(v=SQL.110).aspx) has been updated. It now includes the documentation for the SyncSvcUtilHelper UI tool, which is built on top of the SyncSvcUtil command-line tool. This UI tool exposes all the functionalities supported by the command-line tool. In addition, it lets you create or edit a configuration file that you can use later to provision/deprovision SQL Server/SQL Azure databases and to generate server/client code.
The link you have in your post does not work because of the extra parenthesis at the end.
