-// Commit date: 29 October 2016
-// Commit author: https://github.com/nikrolls
-// Commit message: "Implement cacheStorage using IndexedDB"
-
-// The original imported code has been subsequently modified as it was not
-// compatible with Firefox.
-// (a Promise thing, see https://github.com/dfahlander/Dexie.js/issues/317)
-// Furthermore, code to migrate from browser.storage.local to vAPI.storage
-// has been added, for seamless migration of cache-related entries into
-// indexedDB.
-
-// https://bugzilla.mozilla.org/show_bug.cgi?id=1371255
-//   Firefox-specific: we use indexedDB because browser.storage.local() has
-//   poor performance in Firefox.
-// https://github.com/uBlockOrigin/uBlock-issues/issues/328
-//   Use IndexedDB for Chromium as well, to take advantage of LZ4
-//   compression.
-// https://github.com/uBlockOrigin/uBlock-issues/issues/399
-//   Revert Chromium support of IndexedDB, use advanced setting to force
-//   IndexedDB.
-// https://github.com/uBlockOrigin/uBlock-issues/issues/409
-//   Allow forcing the use of webext storage on Firefox.

+ * 
+ * Structured-Cloneable to Unicode-Only SERIALIZER
+ * 
+ * Purpose:
+ * 
+ * Serialize/deserialize arbitrary JS data to/from well-formed Unicode strings.
+ * 
+ * The browser does not expose an API to serialize structured-cloneable types
+ * into a single string. JSON.stringify() does not support complex JavaScript
+ * objects, and does not support references to composite types. Unless the
+ * data to serialize is only JS strings, it is difficult to easily switch
+ * from one type of storage to another.
+ * 
+ * Serializing to a well-formed Unicode string allows to store structured-
+ * cloneable data to any storage. Not all storages support storing binary data,
+ * but all storages support storing Unicode strings.
+ * 
+ * Structured-cloneable types:
+ * https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm#supported_types
+ * 
+ * ----------------+------------------+------------------+----------------------
+ * Data types      | String           | JSONable         | structured-cloneable
+ * ================+============================================================
+ * document.cookie | Yes              | No               | No
+ * ----------------+------------------+------------------+----------------------
+ * localStorage    | Yes              | No               | No
+ * ----------------+------------------+------------------+----------------------
+ * IndexedDB       | Yes              | Yes              | Yes
+ * ----------------+------------------+------------------+----------------------
+ * browser.storage | Yes              | Yes              | No
+ * ----------------+------------------+------------------+----------------------
+ * Cache API       | Yes              | No               | No
+ * ----------------+------------------+------------------+----------------------
+ * 
+ * The above table shows that only JS strings can be persisted natively to all
+ * types of storage. The purpose of this library is to convert
+ * structure-cloneable data (which is a superset of JSONable data) into a
+ * single JS string. The resulting string is meant to be as small as possible.
+ * As a result, it is not human-readable, though it contains only printable
+ * ASCII characters -- and possibly Unicode characters beyond ASCII.
+ * 
+ * The resulting JS string will not contain characters which require escaping
+ * should it be converted to a JSON value. However it may contain characters
+ * which require escaping should it be converted to a URI component.
+ * 
+ * Characteristics:
+ * 
+ * - Serializes/deserializes data to/from a single well-formed Unicode string
+ * - Strings do not require escaping, i.e. they are stored as-is
+ * - Supports multiple references to same object
+ * - Supports reference cycles
+ * - Supports synchronous and asynchronous API
+ * - Supports usage of Worker
+ * - Optionally supports LZ4 compression
+ * 
+ * TODO:
+ * 
+ * - Harden against unexpected conditions, such as corrupted string during
+ *   deserialization.
+ * - Evaluate supporting checksum.
