我用的是一个开源的工具subversion在A机器，它里面有一个hooks的文件，当版本库有变化的时候，就通过hooks脚本发邮件，邮件服务器sendmail在B机器。

# Well... that isn't strictly true. The contents of the files
# might not be UTF-8, so the "diff" portion will be hosed.
#
# If you want a truly "proper" commit message, then you'd use
# multipart MIME messages, with each file going into its own part,
# and labeled with an appropriate MIME type and charset. Of
# course, we haven't defined a charset property yet, but no biggy.
#
# Going with multipart will surely throw out the notion of "cut
# out the patch from the email and apply." But then again: the
# commit emailer could see that all portions are in the same
# charset and skip the multipart thang.
#
# etc etc
#
# Basically: adding/tweaking the content-type is nice, but don't
# think that is the proper solution.
