i think a good initial example for anyvc would be one of the unittests

def test_build_first_commit(mgr):
    repo = mgr.make_repo('repo')
    with repo.transaction(message='initial', author='test') as root:
        with root.join('test.txt').open('w') as f:
            f.write("text")

    with repo.get_default_head() as root:
        with root.join("test.txt").open() as f:
            content = f.read()
            assert content == 'text'

this test creates a repo, an initial commit, then asserts the content
mgr is a utility to manage the directories where tests dump their data
make_repo creates the repository object that should "be" in another
object when using py.execnet

i'll try to extract something semilar for pida later
