[O] icalendar-import-file into org

[AW]

Hi!

I'd like to have an external calendar file displayed in org and was very glad 
to find a hint in the manual. The name of the external calendar file is 
"office.ics".

So I wrote into my .emacs-file:

(icalendar-import-file "office.ics" "Diary")
(setq org-agenda-include-diary t)

As you can imagine, that caused an import of "office.ics" _every_ time I 
started 
Emacs. So I ended with a huge calendar file full of (no, not stars)[1] 
repetitions of "office.ics".

The trouble obviously is the import into "Diary". If I could write

(setq org-agenda-include "office.ics" t)

-- but as I'm not a programmer, I do not know how to do that.

If someone had a helping hand, I'd be glad,

Regards,

Alexander
