ortoiseSVN 64位中文版是windows下最好用的subversion版本控制系统的免费开源客户端，TortoiseSVN又称海龟SVN，跟Windows的资源管理器结合操作方便简单，可以超越时间的管理文件和目录。文件保存在中央版本库，除了能记住文件和目录的每次修改以外，版本库非常像普通的文件服务器。你可以将文件恢复到过去的版本，并且可以通过检查历史知道数据做了哪些修改，谁做的修改。这就是为什么许多人将 Subversion 和版本控制系统看作一种“时间机器”。(OrtoiseSVN 64 bit Chinese version is the free open source client of subversion version control system, which is best used by windows. TortoiseSVN is also called turtle SVN, which is convenient and simple to operate with Windows resource manager, and can exceed time management files and directories. The file is stored in a central version library. In addition to remembering each modification of the file and directory, the version library is very like a common file server. You can restore the file to the previous version, and you can check the history to know what changes the data has made and who makes the changes. This is why many people think of Subversion and version control systems as a "time machine".)
