-**NOTE:**  Historically the file format was written as:
+**NOTE:**   All integers are stored highest byte first (regardless of size).
+  * The entries are ordered according to key; Lowest key first.
+Sometimes the file format is shown as:
 <code cpp>
 struct entry_t {
-   uint64 key;
+   uint64_t key;
-   uint16 move;
+   uint16_t move;

-   uint16 n;
+   uint16_t n;
-   uint16 sum;
+   uint16_t sum;
 };
 </code>
+  * This still represents the same data.
