git tool to keep a subversion mirror

I am actively using git for my project. Thanks everyone envolved.

However, I got tired of administering own web server and registered my project at sourceforge. Unlike repo.or.cz (thanks again for everyone envolved), they do not provide git hosting. But a project without a source repository is non-sence.

I am not in any way going to use Subversion after I tried git, but I need to be able to export to a Subversion repository. I found an excellent tool called 'git-svn'. However, the flawed nature of Subversion put shackles on normal git usage after you do 'git-svn init'.

Since git is the best scm system, my situation is probably quite common. So I am filing these patches.

There is a 'git-svn' command which does want I need, so I created a simple wrapper around it. I also found that 'git-svn commit-diff' is having a small trouble dealing with root <tree-ish>, which is corrected by an attached patch.
