# Use-case:
# - We have multiple git repositories but want to merge them together for simplicity / using a monorepo / etc.
# - We can not lose the git history and tags
# - The new structure can be arbitrary
#
# Solution:
# - Create a tmp directory and clone all previous repos
# - Install git filter-repo via pip
# - In each of these repos, use the git filter-repo command to move all files to any new directory inside the repository
# - cd anywhere and create your new repository
