@deprecated(
    reason="\n\
Prefer using `create_file_and_commit(filename, committer_date={your_date})` to influence the order of tags.\n\
This is because lightweight tags (like the ones created here) use the commit's creatordate which we can specify \
with the GIT_COMMITTER_DATE flag, instead of waiting entire seconds during tests."

def wait_for_tag():
    """Deprecated -- use `create_file_and_commit(filename, committer_date={your_date})` to order tags instead

    Wait for tag.

    The resolution of timestamps is 1 second, so we need to wait
    to create another tag unfortunately.

    This means:
    If we create 2 tags under the same second, they might be returned in the wrong order
