Grabbing SVN revision number using ANT

I needed to pull the revision number from SVN using ANT. A google search came up with the following pages: Getting Subversion Revision in Ant and Creating a Build Number With Ant and Subversion. Both had nice solutions but I noticed on both when you scrolled down the comments a fellow by the name of Udo Stark had come up with a much easier solution.

Thanks Udo!
