Subversion, or pretty much any version control system, is certainly better than email. It maintains a history of all the changes. This way you do not end up with a zillion copies of your document that you cannot make heads or tails out of. With a version control system, every time you commit a set of changes you write a comment describing what you did. Then you can look over the log to see what was changed when and by whom. You can easily look at the differences between versions and easily roll back changes if you need to. You also always have easy remote access to the current version of your document without having to remember which file name you used for it: you simply do an update of your working directory, or checkout the head version.

Subversion，或者几乎任何版本控制系统，肯定比电子邮件更好。它保留了所有更改的历史记录。这样，您就不会得到无数份无法辨认的文档副本。使用版本控制系统，每次提交一组更改时，您都会写一条注释来描述您所做的事情。然后您可以查看日志以了解更改内容、更改时间和更改者。您可以轻松查看版本之间的差异，并根据需要轻松回滚更改。您还可以轻松地远程访问文档的当前版本，而无需记住您使用的文件名：您只需更新工作目录或签出头版本即可。
