I looked at your mini-primer webpage, but can't find the answer to my question?

How cat one track multiple branches with git without keeping entirely separate trees?

I see there is a git worktree command, which can keep two or more branches in much diskspace than keeping the trees entirely separately (as I did with subversion and cvs).

In my case, I would want to be able to choose between main and stable-13 when compiling; have given up on releng-12 because of problems with ethernet and wireless drivers.
