+(require 'org-capture)
+
+;; turn the e-mails sent MS-Exchange about invitation/appointments into org-TODOs
+;; using 'org-capture'.
+
+;; The idea is that you select (mark) the parts of the email you want to add to
+;; your org-todo item, and then invoke M-x org-exchange-capture-invitation
+
+;; Some caveats:
+
+;;  - obviously, this is just a one-way copy, it won't make you 'accept' an
+;;    invitation, nor does it get any updates
+
+;;  - it seems to work with the emails I get from Exchange (I've encountered two
+;;    different kinds). But there may be more; at least the ones I get that are
+;;    in English, there are other versions as well. I'd be interested in
+;;    extending the regexps with more cases.
+;;
+;;  - it does not take time-zones into account (yet)
+;;
+;;  NOTE:
+;;  It does NOT handle yet:
+;;     When: 12.08.2010 12:00-14:00 (GMT+02:00) Helsinki, ...
+;;    When: \\([0-9]\\{2\\}\.[0-9]\\{2\\}\.[0-9]\\{4\\}\\)
+
+;;    When: 20. syyskuuta 2010 12:00-12:45 (GMT+02:00) Helsinki,  ....
+
+;;  When: Occurs every Thursday effective 19.08.2010 from 14:00 to 15:30
+;;  (GMT+02:00) Helsinki, ...
+
+;;  - it requires org-capture, which is fairly new; it should be easy to support
+;;    org-remember as well though. Also, I only tested with Wanderlust as e-mail
+;;    client; it *should* work with others as well though... 
+
+;; Note that that the message buffer must be the active buffer;
+;; ie. it won't work in the 'Summary' (Wanderlust)
