+/* There are a number of Shared Object Header Message-specific structs here.
+ *
+ * The H5SM_master_table_t is pointed to by the file superblock. Since a file
+ * can have more than one SOHM index, this table collects all the indexes into
+ * one place. It holds an array of H5SM_index_header_t structs.
+ *
+ * An H5SM_index_header_t is actually the for a given index. It holds
+ * the number of messages in the index, the types of messages in the index,
+ * etc. It also records whether the index is a list or a b-tree, and has
+ * the address of the list or b-tree.
+ *
+ * If the index is a list, the address in the index header should be given
+ * to the cache, which can load it into a H5SM_list_t struct. This is mostly
+ * just a header for the cache information; it contains a pointer back to
+ * the index header and an unsorted array of messages.
+ *
+ * These messages are H5SM_sohm_t structs. They hold the actual SOHM's
+ * address, hash value, and refcount.
+ *
+ * If the index is a b-tree, the H5SM_index_header_t struct holds the address
+ * of the b-tree instead of the address of a H5SM_list_t. The B-tree's nodes
+ * are still 'H5SM_sohm_t's.
+ *
+ * H5SM_mesg_key_t structs are used to search lists and B-trees for a certain
+ * message. They correspond to a message that hasn't yet been written to
