Removing .svn files from all directories

Possible Duplicate: How do you remove Subversion control for a folder? Command line to delete matching files and directories recursively I recently converted my cvs repository to svn using cvs2svn and I recently noticed that every directory has a hidden folder called .svn. My current build script copies a lot of directories from my versioned resources directories and it ends up copying the .svn files. Is there anyway to make svn not include these files when I checkout or do I need to write a script to delete all these .svn files. There are many files that have these hidden .svn directories so this would be a pain unless I could write a recursive script to do this but I don't if I can do this for my windows installer. Is there an easy way to stop svn from putting this hidden directory everywhere in my project?
