I have a number of files I wish to add to subversion. Instead of taking my time and adding each individual one, I decided to be a smart-arse and do a:

svn add *

.. which was a mistake. Is there a way I can 'unadd' everything? There's about 7 files I wanted to add... it's now highlighted an extra 500+ auto-generated files I didn't mean to add!

I haven't committed it yet so hopefully there's a way to undo this!!
