+ * A struct content corresponds to a single url.
+ *
+ * It is in one of the following states:
+ *   CONTENT_FETCHING - the data is being fetched and/or converted
+ *                      for use by the browser
+ *   CONTENT_READY - the content has been processed and is ready
+ *                      to display
+ *
+ * The converted data is stored in the cache, not the source data.
+ * Users of the structure are counted in use_count; when use_count = 0
+ * the content may be removed from the memory cache.
