(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 djcb-capture-exchange-invite;
;; 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 are in
;; English, there are probably other versions as well. I'd be interested in
;; extending the regexps with more cases.
;; 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)
