+doc: |
+  The metadata stored by Android at the beginning of a "super" partition, which
+  is what it calls a disk partition that holds one or more Dynamic Partitions.
+  Dynamic Partitions do more or less the same thing that LVM does on Linux,
+  allowing Android to map ranges of non-contiguous extents to a single logical
+  device. This metadata holds that mapping.
