I tried that, but it has the unfortunate effect of adding all my TODO
entries into the calendar.

I want unscheduled TODO items to be in tags-todo lists only (for @contexts
in GTD parlance), and scheduled TODO items to appear in the weekly agenda
and iCalendar files. (And nothing else going to iCalendar.)

I have been able to set everything up except for the last piece in
parentheses above.

Any other thoughts?

Cheers,
Chris
