[arch-general] version control system for normal user

Hi, I'm a normal user on a workstation, without root privilege. Usually, I have to test and revise the source code, while after lots of revisions, I get confused about what's new and what's old. I tried subversion, but a svn server with root privilege is required as daemon. So I wonder if there's a version control system which I can run as a normal user. Any recommendations? Thanks in advance. Jiawei Shao
