SVN最大版本數字：2147483647

 If you're using a 32-bit computer it's 2147483647, that's 2³¹-1, the maximum value of a signed 32-bit integer. For a 64-bit computer, it's... more. In any case, it should be enough for any practical purpose where humans are doing commits.    

若是你在使用32位的計算機，這個數字是2147483647，即2³²-1，32位無符號數的最大值！

而64位系統。。。它會更大……在任什麼時候候，這個數字都會足夠你用了！！！呵呵？………………
