Update to 3.1.6:

* Version 3.1 Patch 6 - 2008-11-16

- MAJOR ENHANCEMENT: A new OMITFUNC clause gives you additional
  control and flexibility over "omitted days" calculations.  This is
  useful when holidays influence the timing of events several days
  later.  See "COMPUTED LOCAL OMITS" in the man page.

- ENHANCEMENT: The new evaltrig() built-in function lets you evaluate triggers
  from within an expression.

- ENHANCEMENT: The new weekno() built-in function returns the ISO 8601
  week number of a date.

- ENHANCEMENT: The "WEEK" special lets you annotate calendar output \ 
with the
  week number.  The TkRemind, rem2ps and rem2html back-ends support WEEK.

- MINOR ENHANCEMENT: You can control whether timed reminders come before or
  after non-timed reminders with the "-g" flag.

- BUG FIX: TkRemind did not work correctly if ~/.reminders was a directory.

- BUG FIX: TkRemind incorrectly invoked Remind with the "-a" flag when
  showing today's reminders.

- BUG FIX: In certain cases, a trigger containing a day, month and
  weekday would fail if it needed to cross a year boundary.  This has
  been fixed.
