How do you recursively delete all hidden files in a directory on UNIX?

I have been searching for a while, but can't seem to get a succinct solution. I have a Mac with a folder that I want to clean of all hidden files/directories - anything hidden. It used to be a Eclipse workspace with a lot of .metadata/.svn stuff, and I'm fine with all of it being removed. How can I do this (either with a shell script, Applescript, etc). Thanks a lot in advance!
