 What Ben's working on now.
 --------------------------
 
-Expression parser/optimizer/evaluator revisions:
+Update q2c input format description.
 
-       * Testing.
+Fix portable file description in documentation, bring code in sync.
 
-       * Add random distributions.
+Rewrite output subsystem, break into multiple processes.
 
-       * Get rid of Boolean/integer type mismatch errors.
+CROSSTABS needs to be re-examined.
 
-Procedures need to be able to make multiple passes.
+RANK, which is needed for the Wilcoxon signed-rank statistic, Mann-Whitney U,
+Kruskal-Wallis on NPAR TESTS and for Spearman and the Johnkheere trend test (in
+other procedures).
 
-Write a better descriptive stats evaluator based on NR two-pass technique,
-revise all existing code to use it.
+TODO
+----
 
-Update q2c input format description.
+Add compression to casefiles.
 
-Rewrite output subsystem, break into multiple processes.
+Expressions need to be able to abbreviate function names.  XDATE.QUARTER
+abbreviates to XDA.QUA, etc.
 
-CROSSTABS needs to be re-examined.
+The expression tests need tests for XDATE and a few others, see
+tests/xforms/expressions.sh comments for details.
