I'm in a situation where I have many multiple software repos. Some in git and some in svn. To build or work on a given project, I need to checkout or clone those various repos together in a working directory. Other than custom scripts, are there tools available that are VCS agnostic that could help with this task? I've been trying all sorts of search terms, but invariably end up with git submodules or git-repo.

Thanks in advance, fediverse!
