gguf:metadata-value

(gguf:metadata-value file key &optional default)

The value the file gives the metadata key key, or default when it has no such key. A GGUF boolean false is a stored nil, so absence is told from falsity by asking the table whether the key is present rather than by looking at the value: default really does mean absent.
