- * prefix of the key string and storing an enumerator instead to save memory.
- *
- * However, this means if new prefixes are introduced, they are not immediately
- * supported since SquashFS may not have an enumerator defined for them.

- * prefix, or it has recently been added but the version of libsquashfs you
- * are using doesn't support it.
