         * would be desirable to rewrite following logic more concisely, using,
         * e.g., the recently-introduced ale_eval to facilitate abstraction, so
         * that the split in functionality can be performed more cleanly.
+        *
+        * The split in following should probably assign to ALE functionality
+        * like this:
+        *
+        * Working one's way up the hierarchy,
+        *
+        *   * If file data is available for both prev. and current transf's,
+        *        -> use established 'delta --follow semantics' described below
+        *   * If file data is available for only current transf.,
+        *        -> adjust file current according to parent adjustment rel. to file.
+        *   * else (2 cases)
+        *        -> use parent calc. adj. by any prev. final against its parent.
+        *
+        * And assign to libale functionality like this:
+        *
+        *   * correct each element based on an estimated error from alignment-
+        *     calculated change in the parent element.
