Let's make a git repository out of whole cloth.

Git repos are stored in .git:

fakegit$ mkdir .git

They have a "symbolic ref" (which are text files, see man git-symbolic-ref) named HEAD, pointing to the currently checked-out branch. Let's use master. Branches are refs under refs/heads (see man git-branch):

fakegit ((unknown))$ echo 'ref: refs/heads/master' > .git/HEAD
