+usage_mirrorClone=Set up a mirror of the source repository. This implies --bare. Compared to --bare, --mirror not only maps \
+local branches of the source to local branches of the target, it maps all refs (including remote-tracking branches, notes etc.) \
+and sets up a refspec configuration such that all these refs are overwritten by a git remote update in the target repository.
