// Publicode rules used to be defined as a list of objects identified by the concatenation of their `espace` and `nom` attributes.
// They're now values indexed by the concatenation as a key
// See the PR that enacted this : https://github.com/betagouv/mon-entreprise/pull/719

// Usage : `cat source\règles\base.yaml | node migrate-publicode.js > newFile.yaml`
