[O] Displaying agenda for today instead of diary with the calendar

[Christian Wittern]

Dear org-moders,

Over the years I have gradually moved most of my planning from the Emacs 
diary to org-mode. However, when I call up the Emacs calendar, it still 
displays the day-view of my diary, which does not have relevant information 
anymore.  I would like to replace it with the agenda buffer.

Upon investigation, it seems that calendar calls 'view-diary-entries' to 
display the diary.  Has anybody here managed to replace this with an 
appropriate call to display the agenda buffer?  How would I go ahead to 
achieve this?

Any help appreciated,

Christian
