Usage: run "$0 /path/to/git/dir [project...]" or "$0 /path/to/git/dir ALL"
This util script can be used in case of rollback to ReviewDB during an unsuccessful
migration to NoteDB or simply while testing the migration process.
It will remove all the refs used by NoteDB added during the migration (i.e.: change meta refs and sequence ref).
