+nostromo uses a uuid to determine if a manifest is unique or not.
+When using sync to get new manifests, nostromo will only apply the
+changes if it detects a different identifier.
+
+This command allows regenerating the uuid to allow for publishing
+and pulling updated manifests. Note that using standard nostromo
+commands automatically updates the identifier. This command can be
+used if manual updates were made to a manifest.
+
+Omitting the name of the manifest will apply to the core manifest.`,
