I got a "Project A" in repository. But in that project I'm using a library, which is hosted on Google Code. There is my question: is there any way, to have that library files "hooked" to Google Code SVN, and simultaneously my project in my repo (it's parent to that library), so I can commit library files into my repository when I decide, that outer project revision is ok?

I've tried to do checkout in the library folder, files were downloaded from Google's Code repository. But I that case wasn't able to add them to my repository - they weren't visible in "Add" window.
