I think Charles is referring to the following in org-capture-templates's
doc string:

,----
|              (file+function "path/to/file" function-finding-location)
|                  A function to find the right location in the file
| 
|              ...
| 
|              (function function-finding-location)
|                 Most general way, write your own function to find both
|                 file and location
`----

I tried using the first (in a very simple minded way) but it was late last
night, I was tired and I couldn't get it to work in five minures, so I gave
up:

(WARNING: DOES NOT WORK)
,----
| (setq org-capture-templates
| '(...
|   ("X" "Experimental function for Charles Cave" entry (file+function 
"~/lib/org/charles.org" cc-date-tree) "* DONE %?
|   %U %a" :prepend t)
|   ...
|   ))
| 
| (defun cc-date-tree ()
|   (let ((year 2010)
|         (weeknum 32))
|     (format "%4d-Week-%2d" year weeknum)))
`----
(WARNING: DOES NOT WORK)

So maybe I have it completely wrong, maybe this is close, but at this
point I just don't know.

Also, I saw in the doc string the following:

,----
|              (file+datetree "path/to/file")
|                  Will create a heading in a date tree
`----

which might do exactly what Charles wants in this case, without having
to write a function? But I have no idea how datetrees work, so this
too might be off.

Thanks,
Nick
