Problem / Steps to reproduce

Let's assume test_dir is a dir with a lots of git repos. Let's assume we want test_dir to be a git repository itself, with a nice README.md explaining how to checkout included repos:

cd test_dir
git init .
mani init
error: exit status 1

You can't init many, it returns an error.

Workaround: Move temporarly the .git folder to TMP_GIT, do the mani init and rename TMP_GIT to .git again.
