+
+ * Moved the declarations relating to values to their own header file
+ (val.h)
+
+ * Added levene.c and levene.h
+
+ * vars-atr.c: Changed the signature of compare_values to
+ take const * arguments.
+
+ * t-test.q: Changed the structure of struct t_test_proc
+ variables now contain their own group statistics information.
+ Eventually, t_test_proc might get renamed, because it'd be
+ applicable to other commands too.

+ Add auxiliary argument to procedure() interface. Associated small
+ clean-ups of vfm interface.
+
+ * Updated every caller of procedure() and process_active_file() to
+ reflect modified interface. Simple, ordinary changes not listed
+ otherwise below.
+
+ * Updated every function that implements struct case_stream's
+ `read' function to take a write_case_func and a write_case_data.
+ Also updated every caller of write_case() to instead call them
+ through these arguments. In some cases this meant that the extra
+ args had to be threaded through a couple of extra levels. This
+ wasn't difficult or interesting so the details won't be given.

+ transformations, so that they know where to send their cases.
+ It's a big kluge. Also kluge in END CASE.
