R-Forge is essentially an online subversion repo with an automated R  
package build system behind it. It does not modify your svn files as  

You need to manually bump the version information in the DESCRIPTION  
file in order to change the actual package version for the next  
nightly build.

Successive commits will bump the svn revision counter, but not the  
package version. This gives you the ability to commit multiple changes  
to your code, without modifying the package version until you  
explicitly want to. You can then decide when to submit to CRAN when  
ready, which R-Forge makes easy to do as well.
