Wanderlust and org-capture

["Cédric Chépied" <cedric.chepied@gmail.com>]

Hi,

I'm using wanderlust to read and write emails in emacs. I wanted to use
org-capture to add TODOs in my org files.

In org-capture-templates documentation there is a line talking about wanderlust
(I think):

vm, wl, mh, mew, rmail, |  %:type %:subject %:message-id

But I was unable to use %:type or %:whatever in my template to capture
wanderlust messages.

I found an org-rmail.el file in org-mode sources but I couldn't find org-wl.el
and I assumed this is the reason why I can't use org-capture. I wrote an
org-wl.el file based on org-rmail. you can find sources here:
https://github.com/chep/org-wl
Feel free to comment it and to use it if you want.
