Often, when considering a new version control system, the easiest way to get started is to migrate an existing repository over to it. With Git, it is now quite easy to migrate an existing Subversion repository, including all history, over to Git.
$ git svn clone [subversion_repository_url] /path/to/git/repository
$ cd /path/to/git/repository
$ git remote add origin git@subdomain.unfuddle.com:subdomain/abbreviation.git
$ git push origin master
Note that 'git svn clone' will create the Git repository.
