  What happened is that you added paths to a directory which was only made for 
SVN checkouts. The purpose of that checkAddedPaths, is to be sure that if you 
added something (like here) it's not deleted without letting it you knows it.

  The SVN system manage its own directory and keep it clean for other unwanted 
products. If you want to add products to the same directory, you need to fetch 
them by SVN as well. Or you can define a different directory where you can 
additional products via other means (see 
http://docs.infrae.com/silva/buildout/extending.html).

  And the SVN directory is in parts because, like everything which is in 
parts, it can be deleted to be reinstalled when you upgrade. If you move it 
outside of parts, well, this rule still does apply (it will still be deleted, 
after checking you didn't add or modify anything).
