GIT is nice for its portability.
Here is a short memo in case you want to export a SVN (Subversion) repository into a GIT environment.
You need first to install the package git-svn and subversion.
First initialize your local repository.
Then setup the repository to fetch the svn URL you are looking for. I found that the easiest solution to check out a SVN repository was by playing with the local repository configuration to get a remote svn repository.
git config --add svn-remote.$SVN_REPO.url http://url/to/check/out
git config --add svn-remote.$SVN_REPO.fetch :refs/remotes/$SVN_REPO
git svn fetch $SVN_REPO [-r$REV_NUMBER]
git svn rebase $SVN_REPO
SVN_REPO is the identifier you want to associate with your local repository.
REV_NUMBER can be added to specify a version number to check out.
What happens here is that the SVN repository is checked out as a remote branch.
~/code/test(master) $ git branch -a
Once this is done, you can use your local copy and check that in a central git repository or merge that with other works.
When SVN has to go through a proxy, it is important to set the file ~/.subversion/servers with the following options.
http-proxy-host = proxy.server.com
http-proxy-port = 8080
