[git-svn] howto select a part of the tree

Hi,

I have the following setup and would like to know it my thought workflow 
would be easily doable with git-svn.

I have a repository which contains at the moment 5 eclipse projects. two 
of them are directly in the svn root and i'm not interested in them. the 
other three are mine and I'd like to use them as separate eclipse 
projects as i currently do when i check them out as seperate projects 
into the workspace with subversive.

is this possible or should i just forget it.

Regards Michael
