[Orgmode] Org-expiry: How to define keyword for org-expiry-add-keyword

[Markus Heller]

Hello,

please help a newbie with org-expiry.el :)

I have a file like this:

expiry.org

* ACTIVE Test task
  :PROPERTIES:
    :EXPIRY: <2010-01-04 Mon 11:12>
  :END:

I want org-expiry to change the keyword from ACTIVE to EXPIRED.  These 
keywords are defined in my .emacs as follows:

(setq org-todo-keywords
   (quote ((sequence "TODO(t)" "STARTED(s!)" "WAITING(w@/@)" 
"APPT(a@/!)" "|" "DONE(d@/@)" "CANCELED(c@/@)" "DEFERRED(f)")
           (sequence "ACTIVE" "|" "EXPIRED"))))

If I type M-x org-expiry-process-entries in expiry.org, I get the 
following error:

Symbol's function definition is void: org-expiry-handler function

I have defined this to be org-expiry-add-keyword, but how do I define 
the actual keyword?

Thanks
Markus
