Hi Vimmers, As many many people requested, I finally decide to obey the svn book's advice and will build up trunk/ tags/ and branches/. But so far as you know, sf.net's svn service is not in a good status so I'm not able to commit all changes once. So I have to commit many times to build up this structure.
So, PLEASE DON'T UPDATE YOUR LOCAL SVN REPOSITORY UNTIL THE WORK IS DONE. OR YOU WILL GET A CORRUPTED VERSION. Best regards, Edward L. Fox
