[Users] Checking out branches with GetComponents

Hi,

Is it currently possible to specify which branch to check out with GetComponents? For the release, we are planning on making a new branch in each repository which will be the "release branch", called ET_2010_06. For each type of repository (SVN, CVS, git) the einsteintoolkit.th thorn list will be updated to check out this branch. Is this possible?

It seems that git clone has a "-b" option to specify which branch to check out after the repository is cloned, but this doesn't seem to exist in anything but the latest versions of git (for example, it exists in 1.7.1 but not in 1.6.1). So a separate "git checkout" command will have to be run by GetComponents.
