### Using xl-meta

## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a
well defined data structure. To understand `xl.meta` here are the few things to start with

			continue

		if !inclDeleted && meta.isLatestDeletemarker() && meta.isObject() && !meta.isObjectDir() {
			continue
