Как добавить много проектов в один репозиторий git? [закрыто]

Возможна опция через --орфан ветвь. Viz manual:

--orphan
    Create a new orphan branch, named <new_branch>, started from
    <start_point> and switch to it. The first commit made on this new
    branch will have no parents and it will be the root of a new history
    totally disconnected from all the other branches and commits.
