Subversion Automation
Subversion Automation is a wrapper around Subversion that automates
and standardizes branching and merging. The primary goal of the
project is to simplify the more complex features of Subversion and
therefore encouraging the use of such features.
Introduction Screencast

Watch the 10 minute introduction to sc screencast.
Subversion Automation includes a command line utility called sva. In
prior releases (before 1.1.0), the sva utility was named sc.
Therefore this screencast will mention and demonstrate the sc utility.
All references to the sc utility can safely be replaced with the sva
utility. As a matter of fact, running the sc utility will now produce
a message referring you to the sva utility instead.

repositories to Git, you might want to take a look at this.
