XCode+SVN coloring the modified lines?

I am probably asking for too much: does anyone know a way to get XCode color the lines of code accordi开发者_运维百科ng to their subversion status (modified, added, etc.)? It would be nice to have it integrated in XCode.

AFAIK, Xcode does not provide this functionality. The only way I can think of is to write a script that will do the job.
