ISVNClientAdapter hidden in 1.1.8

Hi,
The Buckminster SVN plugin currently rely on subclipse.core 1.0.x and 
has some direct references to the ISVNClientAdapter. It uses it to 
checkout files etc. since it's important for us to do things in two 
steps. The first step is to perform checkouts to the file system (and 
not to the Eclipse workspace), the second involves binding selected 
artifacts to the Eclipse workspace, possibly after some modifications. 
In particular, we do not want to make Eclipse aware of the things we 
checkout until we decide its time to do so (which might be never).

I tried the SVN 1.1.8 today and discovered that the ISVNClientAdapter is 
no longer visible. I'm all for encapsulation but I need some help with 
this. Is it still possible to do checkouts without creating workspace 
resources? If so, how do I do that?

Kind regards,
Thomas Hallgren
