[Remind-Fans] weekly shift rotation

[Rob Hamrick]

> Really, what you have is a 28-day cycle, so here's how I would do it:

> FSET _cycle(x) ((x - '2008-12-08') / 7) % 4
> REM Mon Tue Wed Thu Fri SATISFY [_cycle(trigdate()) == 0] MSG late%
> REM Mon Tue Wed Thu Fri SATISFY [_cycle(trigdate()) == 1] MSG off%
> REM Mon Tue Wed Thu Fri SATISFY [_cycle(trigdate()) == 2] MSG early%
> REM Mon Tue Wed Thu Fri SATISFY [_cycle(trigdate()) == 3] MSG swing%

That's beautiful, thanks!  Much better.  -r
