SVN最大版本数字：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位的计算机，这个数字是2147483647，即2³²-1，32位无符号数的最大值！

而64位系统。。。它会更大……在任什么时候候，这个数字都会足够你用了！！！呵呵？………………
