svn2git question: Build directory inserted at top level?

All,

I'm converting repositories from svn to git using svn2git.  I have a repo with the following hierarchy:

trunk/ dist/ tags/ branches/ REbranches/

Ultimately I want to convert everything except the dist directory but am trying to understand what svn2git is doing and why.

I ran the command to see what I would get just importing trunk:

svn2git -v --nobranches --notags  http://poc.emc.com/repos/POCcs

After the conversion completed I had the following:

buildadm@suse-s11:/work/POCcs> ls Automation build_cs_rpm.pl ControlStation depends.properties

Then I ran the following command because I wanted to include the branches as well as the trunk in the conversion:

svn2git -v --notags  http://poc.emc.com/repos/POCcs

When I include the branches in the conversion I get a Build directory at the top level and then the usual directory structure of the repo.  Where is the Build dir coming from?  Is svn2git doing that?  Or is it finding that somewhere somehow in the repo?

buildadm@suse-s11:/work/POCcs> ls Build buildadm@suse-s11:/work/POCcs/Build> ls Automation build_cs_rpm.pl ControlStation depends.properties

Thanks for any help.
