Subversion

Really, subversion is no longer where it's at (although it's an excellent replacement for cvs, should any unfortunate souls still be using that in this day and age). Try distributed source code control systems like git.

Keeping $HOME in subversion

• Don't keep transient files under control, particularly things like browser cache or bash history.
• Don't keep things like ssh and GnuPG keys in there; use symbolic links and a second repository
